Watering Care
Watering Care
Oleander is a remarkably drought-tolerant plant. Young plants require regular watering until they become established, but mature plants should be watered infrequently and thoroughly. Although Oleander is drought-tolerant, it will perform best when properly watered. Let the soil dry out between waterings, then give it a good soak.

Fertilizing Care
Fertilizing Care
Oleander doesn't have any particular fertilization needs unless it shows signs of nutrient deficiencies. Test your soil for important nutrients and apply the fertilizer accordingly. On the other hand, plants grown in containers should be fertilized more often. In this case it might be best to apply a balanced, granular fertilizer once a month during the growing season.

What is the best way to water my Oleander?
Your Oleander will not be too picky about how you choose to water it. As such, you can use just about any common watering tool to moisten this plant’s soil. Watering cans, hoses, and even cups will work just fine when it is time to water your Oleander. Regardless of which watering tool you use, you should typically apply the water directly to the soil. In doing so, you should ensure that you moisten all soil areas equally to give all parts of the root system the water it needs. It can help to use filtered water, as tap water can contain particles that are harmful to plants. It is also beneficial to use water that is at or slightly above room temperature, as colder or hotter water can be somewhat shocking to the Oleander. However, the Oleander usually responds well to any kind of water you give it.

What should I do if I water my Oleander too much or too little?
For outdoor plants, especially newly planted plants or plant seedlings, they can be prone to lack of watering. Remember that you need to keep watering enough for a few months when the tree is small or just planted. This is because once the roots are established, Oleander can rely on rain most of the time.
When your Oleander is planted in pots, overwatering is often more likely to.When you accidentally overwater your Oleander, you should be prepared to remedy the situation immediately. First, you should stop watering your plant right away to minimize the effect of your overwatering. After, you should consider removing your Oleander from its pot to inspect its roots. If you find that none of the roots have developed root rot, it may be permissible to return your plant to its container. If you do discover signs of root rot, then you should trim away any roots that have been affected. You may also want to apply a fungicide to prevent further damage. Lastly, you should repot your Oleander in soil that is well-draining. In the case of an underwatered Oleander, simply water this plant more frequently.
Underwatering is often an easy fix. If you underwater, the plant's leaves will tend to droop and dry out and fall off, and the leaves will quickly return to fullness after sufficient watering. Please correct your watering frequency as soon as underwatering occurs.

How often should I water my Oleander?
Most plants that grow naturally outdoors can be allowed to grow normally with rainfall. If your area lacks rainfall, consider giving your plants adequate watering every 2 weeks during the spring and fall. More frequent watering is needed in summer. In winter, when growth becomes slower and plants need less water, water more sparingly. Throughout the winter, you may not give it additional watering at all. If your Oleander is young or newly planted, then you should water more frequently to help it establish, and mature and grow up to have more adaptable and drought tolerant plants.
For potted plants, there are two main ways that you can determine how often to water your Oleander. The first way is to set a predetermined watering schedule. If you choose this route, you should plan to water this plant about once every week or once every other week. However, this approach may not always work as it does not consider the unique conditions of the growing environment for your Oleander .
Your watering frequency can also change depending on the season. For instance, a predetermined watering schedule will likely not suffice during summer when this plant's water needs are highest. An alternative route is to set your watering frequency based on soil moisture. Typically, it is best to wait until the first two to four inches of soil, usually ⅓ to ½ depth of the pots, have dried out entirely before you give more water.

How much water does my Oleander need?
When it comes time to water your Oleander, you may be surprised to find that this plant does not always need a high volume of water. Instead, if only a few inches of soil have dried since your last watering, you can support healthy growth in the Oleander by giving it about five to ten ounces of water every time you water. You can also decide your water volume based on soil moisture. As mentioned above, you should note how many inches of soil have dried out between waterings. A surefire way to make sure your Oleander gets the moisture it needs is to supply enough water to moisten all the soil layers that became dry since the last time you watered. If more than half of the soil has become dry, you should consider giving more water than usual. In those cases, continue adding water until you see excess water draining from your pot’s drainage holes.
If your Oleander is planted in an area that gets plenty of rain outdoors, it may not need additional watering. When the Oleander is young or just getting established, make sure it gets 1-2 inches of rain per week. As it continues to grow and establish, it can survive entirely on rainwater and only when the weather is hot and there is no rainfall at all for 2-3 weeks, then consider giving your Oleander a full watering to prevent them from suffering stress.

How can I tell if i'm watering my Oleander enough?
Overwatering is a far more common problem for the Oleander, and there are several signs you should look for when this occurs. Generally, an overwatered Oleander will have yellowing leaves and may even drop some leaves. Also, overwatering can cause the overall structure of your plant to shrivel and may also promote root rot. On the other hand, an underwatered Oleander will also begin to wilt. It may also display leaves that are brown or brittle to the touch. Whether you see signs of overwatering or underwatering, you should be prepared to intervene and restore the health of your Oleander.

How can I water my Oleander at different growth stages?
When the Oleander is very young, such as when it is in a seedling stage, you will need to give it more water than you would if it were at a mature age. During the early stages of this plant’s life, it is important to keep the soil consistently moist to encourage root development. The same is true for any Oleander that you have transplanted to a new growing location. Also, the Oleander can develop showy flowers and fruits when you give them the correct care. If your Oleander is in a flowering or fruiting phase, you will likely need to give a bit more water than you usually would to support these plant structures.
Read More more
How can I water my Oleander through the seasons?
The seasonal changes will affect how often you water your Oleander. Mainly, during the hottest summer months, you will likely need to increase how much you water this plant, especially if it grows in an area that receives ample sunlight. Strong summer sunlight can cause soil to dry out much faster than usual, meaning that you’ll need to water more frequently. By contrast, your Oleander will need much less water during the winter, as it will not be in an active growing phase. During winter, you can get by with watering once every 2 to 3 weeks or sometimes not at all. For those growing this plant indoors, you should be somewhat wary of appliances such as air conditioners, which can cause your plant to dry out more quickly, which also calls for more frequent watering.

What's the difference between watering my Oleander indoors vs outdoors?
In some cases, your Oleander may not need any supplemental watering when it grows outside and will survive on rainwater alone. However, if you live in an area of little to no rain, you should water this plant about every two weeks. If you belong to the group of people who live out of this plant's natural hardiness zone, you should grow it indoors. In an indoor setting, you should monitor your plant's soil as it can dry out more quickly when it is in a container or when it is exposed to HVAC units such as air conditioners. Those drying factors will lead you to water this plant a bit more often than if you grew it outdoors.

Name story

Common oleander
Its common name is similar to the latin specific epithet, oleander which comes from two sources. From one source, the word is derived partly from arodandrum, lorandrum or rhododendron. While the other part, olea is inspired by its similarity in appearance to Olea europea. From the other source, it is believed that oleander is derived from the latin word, ollyo and aner or andros. The word, ollyo means that "I kill" while andros refers to the meaning of man. As this plant is poisonous and it is the only species in its genus, it is then called common oleander.

Usages

Garden Use
Oleander is a popular ornamental evergreen shrub cultivated since the time of the ancient Romans. It offers great garden appeal with its bright flowers which bloom from late spring through to fall. Oleander makes for a great hedge or screening plant but also looks nice in the back of a border. Since it is only slightly frost-tolerant it can be grown indoors as a houseplant in colder regions. Its salt tolerance also makes it a great option for coastal gardens. This plant grows well with agapanthus 'Peter Pan', crape myrtle, and holly.

Trivia and Interesting Facts

Despite the fact that oleander is so poisonous to many creatures, the caterpillars of the Oleander hawk-moth (Daphnis nerii) are immune to its toxins. In fact, oleander is their main food source, which has led to the introduction of this moth in all areas where the plant is grown ornamentally.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Oleander and Their Toxicity

feedback
Feedback
feedback
* The judgment on toxicity and danger is for reference only. We DO NOT GUARANTEE any accuracy of such judgment. Therefore, you SHALL NOT rely on such judgment. It is IMPORTANT TO SEEK PROFESSIONAL ADVICE in advance when necessary.
Highly Toxic to Humans
Highly Toxic to Humans
Oleander is moderately to highly toxic to humans – instances of ingestion, or physical contact with this plant's sap, should be immediately addressed by medical professionals. While fatal cases of oleander poisoning are very rare, they are possible. All parts of this plant are toxic if ingested. Physical contact with the plant's sap, which is found throughout the plant and is more likely to be exposed if the plant is cut or damaged, may cause dermatological symptoms, including redness and itchiness of the skin. Symptoms following ingestion include low blood pressure, lethargy, an irregular heartbeat, blurred vision, confusion, diarrhea, vomiting, dizziness, fainting and, in extreme cases, death. Be mindful of curious children, as oleanders are an extremely common ornamental plant cultivated in gardens and parks around the world.
Toxic to Dogs
Toxic to Dogs
Nerium oleander is highly toxic to dogs and can be fatal if ingested; consider it a medical emergency if you suspect your dog has eaten any part of this plant (all parts are toxic). Symptoms of poisoning include increased heart rate and diarrhea. Immediate veterinary care is vital.
Toxic to Cats
Toxic to Cats
Due to high concentrations of cardiac glycosides, all parts of the oleander (Nerium oleander) are extremely toxic to cats. The glycosides directly affect the heart, sometimes preventing it from performing properly. Death is not an unknown consequence, and veterinary care is necessary if a cat ingests any part of this plant.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Who Is Most at Risk of Plant Poisoning?
Everyone should keep the following in mind to prevent being poisoned:
1
Do not eat any parts, nor contact with the sap of toxic or unknown plants;
2
If you need to kill it, wear long-sleeved shirts, pants and gloves with sharp tools to dig it out completely;
3
Clean the tools with rubbing alcohol or soap and water but do not do that with bare hands;
4
Clean your hands and skin once exposed to plants with soap and water;
5
Consider using barrier creams that contain bentoquatam to prevent poison oak, ivy and sumac rashes;
6
Dump it in special trash cans in sealed garbage packages;
7
Wear properly when you hiking or working in the wilderness. Long pants, long sleeves, gloves, hiking shoes, etc., that protect you from being hurt by any plants;
8
Once you or your family aren’t feeling well after eating, touching or inhaling anything from toxic plants, please call your doctor for help ASAP!
Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats.

Weed Control About Oleander

feedback
Feedback

Weeds
Oleander is a highly toxic plant that, if ingested, can affect the gastrointestinal system, heart and central nervous system, and even endanger life.
How to Control it
Flower heads can be picked off the plant to prevent its seeds from spreading, enabling you to keep it away from pets and children. Since the oleander has a tough and extensive root system, completely removing it from a garden is difficult, but it can be done. You will need to cut back the plant and then attempt to dig it out, using a variety of different tools, including saws and pry bars. Every single root will need to be removed, otherwise the plant will just grow back. Glyphosate applications (if it's not banned) can help with this, as can pouring bleach into the root zone, although the latter can cause a severe amount of damage to the soil and plant life around it.

Water
Every 1-2 weeks
Oleander originates from the Mediterranean region to southern China, indicative of its adaptability to hot, dry locations, with minimal rainfall. Its style of growth implies an affinity to less frequent yet deep watering, encouraging root growth downwards as is observed in its natural drought-prone environment. Its Mediterranean roots hint toward ample water provision in winters and drier conditions in the summer period in its cultivation.
Watering Techniques
Lighting
Full sun
Oleander thrives best under abundant light exposure, mimicking its original, sunny environment. During each growth stage, it needs a high degree of light for robust development. Should the light be insufficient, the plant may exhibit stunted growth. Conversely, while it can stand a degree of shadow, excessive lack of sun may lead to poor blooming.
Best Sunlight Practices
Temperature
-5 - 43 ℃
The temperature requirements for oleander are relatively moderate, with a preferred temperature range of 59 to 100 ℉ (15 to 38 ℃). It is native to regions with hot, dry summers and mild, wet winters, so it can handle some temperature fluctuation. During the winter, it is important to keep the plant in a location that maintains at least 50 ℉ (10 ℃) to avoid damaging the plant.
Temp for Healthy Growth
Transplant
6-12 feet
The perfect time to transplant oleander is during late spring to mid-summer when it's actively growing. Choose a sunny location with well-drained soil for optimal results. Be gentle with the roots while transplanting; they appreciate a smooth transition to their new home.
Transplant Techniques
Overwinter
-5 - 43 ℃
Oleander hails from the Mediterranean climate, enduring temperate winters with ease. This hardy plant's thick leaves and stem coating act as insulators. However, severe cold can be detrimental, causing leaf drop or plant death. As such, winter care should include preserving warmth. Consider moving potted oleander indoors or mulching garden-planted oleander to safeguard the root system and maintain soil temperature.
Winter Techniques
Pruning
Spring, Winter
A hardy shrub known for its vibrant, toxic blooms and tolerance to drought, oleander benefits significantly from proper pruning. For oleander, remove dead or damaged stems and shape the bush post-blooming. Early spring or winter pruning encourages robust growth and maintains compactness, avoiding legginess. Be cautious of the plant's toxicity; wear gloves and dispose of clippings safely. Pruning not only enhances floral displays but also promotes plant health and vigor.
Pruning techniques
Propagation
Spring, Summer
Oleander propagates most successfully through cuttings during the warmer months of spring and summer. The process is moderately challenging; successful propagation is indicated by new growth. Ensure proper moisture and avoid excessive sun exposure for optimal results.
Propagation Techniques
Brown blotch
Brown spot is a fungal disease that affects the leaves of Oleander, causing leaf loss and plant weakness. Infested leaves develop circular to slightly irregular, reddish-brown to dark brown spots, potentially leading to severe leaf drop and impacting overall plant health.
Learn More About the Disease
Aphids
Aphids, small sap-sucking insects, affect Oleander by sucking the plant's juices and causing the leaves to yellow and curl. Heavy infestations can result in stunted growth and reduced vigor. Some species may also transmit plant diseases, further impacting the Oleander's health.
Learn More About the Disease
flower wilting
Wilting is a devastating plant disease that greatly affects Oleander's health and structural integrity. This disease is characterized by drooping leaves and a general decline in the plant's vitality, which can lead to complete plant death if not promptly managed.
Learn More About the Disease
Leaf blight
Leaf blight, a devastating disease, significantly impacts Oleander's growth, affecting its overall vigour and aesthetics. The disease is caused by fungal pathogens, which leads to telltale symptoms like necrotic spots, leaf wilting, and premature leaf drop.
Learn More About the Disease
Leaf mites
Leaf mites are microscopic pests that feed on Oleander sap, causing damage and potential weakening of the plant. If left untreated, a severe infestation can lead to yellowing, wilting and premature leaf drop, impacting plant health and growth negatively.
Learn More About the Disease
Toxic
Highly Toxic to Humans
Oleander is moderately to highly toxic to humans – instances of ingestion, or physical contact with this plant's sap, should be immediately addressed by medical professionals. While fatal cases of oleander poisoning are very rare, they are possible. All parts of this plant are toxic if ingested. Physical contact with the plant's sap, which is found throughout the plant and is more likely to be exposed if the plant is cut or damaged, may cause dermatological symptoms, including redness and itchiness of the skin. Symptoms following ingestion include low blood pressure, lethargy, an irregular heartbeat, blurred vision, confusion, diarrhea, vomiting, dizziness, fainting and, in extreme cases, death. Be mindful of curious children, as oleanders are an extremely common ornamental plant cultivated in gardens and parks around the world.

Name story

Common oleander
Its common name is similar to the latin specific epithet, oleander which comes from two sources. From one source, the word is derived partly from arodandrum, lorandrum or rhododendron. While the other part, olea is inspired by its similarity in appearance to Olea europea. From the other source, it is believed that oleander is derived from the latin word, ollyo and aner or andros. The word, ollyo means that "I kill" while andros refers to the meaning of man. As this plant is poisonous and it is the only species in its genus, it is then called common oleander.

Usages

Garden Use
Oleander is a popular ornamental evergreen shrub cultivated since the time of the ancient Romans. It offers great garden appeal with its bright flowers which bloom from late spring through to fall. Oleander makes for a great hedge or screening plant but also looks nice in the back of a border. Since it is only slightly frost-tolerant it can be grown indoors as a houseplant in colder regions. Its salt tolerance also makes it a great option for coastal gardens. This plant grows well with agapanthus 'Peter Pan', crape myrtle, and holly.

Trivia and Interesting Facts

Despite the fact that oleander is so poisonous to many creatures, the caterpillars of the Oleander hawk-moth (Daphnis nerii) are immune to its toxins. In fact, oleander is their main food source, which has led to the introduction of this moth in all areas where the plant is grown ornamentally.

Aged yellow and dry

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Oleander and Their Toxicity

feedback
Feedback
feedback
* The judgment on toxicity and danger is for reference only. We DO NOT GUARANTEE any accuracy of such judgment. Therefore, you SHALL NOT rely on such judgment. It is IMPORTANT TO SEEK PROFESSIONAL ADVICE in advance when necessary.
Highly Toxic to Humans
Oleander is moderately to highly toxic to humans – instances of ingestion, or physical contact with this plant's sap, should be immediately addressed by medical professionals. While fatal cases of oleander poisoning are very rare, they are possible. All parts of this plant are toxic if ingested. Physical contact with the plant's sap, which is found throughout the plant and is more likely to be exposed if the plant is cut or damaged, may cause dermatological symptoms, including redness and itchiness of the skin. Symptoms following ingestion include low blood pressure, lethargy, an irregular heartbeat, blurred vision, confusion, diarrhea, vomiting, dizziness, fainting and, in extreme cases, death. Be mindful of curious children, as oleanders are an extremely common ornamental plant cultivated in gardens and parks around the world.
More Info About Toxicity

Toxic to Cats
Due to high concentrations of cardiac glycosides, all parts of the oleander (Nerium oleander) are extremely toxic to cats. The glycosides directly affect the heart, sometimes preventing it from performing properly. Death is not an unknown consequence, and veterinary care is necessary if a cat ingests any part of this plant.

pets
Pets
Some pets are less likely than children to eat and touch just about everything. This is good, as a pet owner. However, you know your pet best, and it is up to you to keep them safe. There are plenty of poisonous weeds that can grow within the confines of your lawn, which might make your dogs or cats ill or worse if they eat them. Try to have an idea of what toxic plants grow in your area and keep them under control and your pets away from them.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Weeds
Oleander is a highly toxic plant that, if ingested, can affect the gastrointestinal system, heart and central nervous system, and even endanger life.
How to Control it
Flower heads can be picked off the plant to prevent its seeds from spreading, enabling you to keep it away from pets and children. Since the oleander has a tough and extensive root system, completely removing it from a garden is difficult, but it can be done. You will need to cut back the plant and then attempt to dig it out, using a variety of different tools, including saws and pry bars. Every single root will need to be removed, otherwise the plant will just grow back. Glyphosate applications (if it's not banned) can help with this, as can pouring bleach into the root zone, although the latter can cause a severe amount of damage to the soil and plant life around it.

Oleander Watering Instructions
Oleander originates from the Mediterranean region to southern China, indicative of its adaptability to hot, dry locations, with minimal rainfall. Its style of growth implies an affinity to less frequent yet deep watering, encouraging root growth downwards as is observed in its natural drought-prone environment. Its Mediterranean roots hint toward ample water provision in winters and drier conditions in the summer period in its cultivation.
When Should I Water My Oleander?
Importance of Timely Watering
Timely watering is crucial for the overall health and growth of the oleander. It enables the plant to efficiently process nutrients, aids in photosynthesis, and helps in maintaining overall structure and strength.
Soil Dryness
One clear indicator that the oleander needs water is the dryness of the soil. To test this, insert your finger about an inch into the soil - if it feels dry to touch, it's a clear signal that the plant requires water. Cracked or crusty topsoil can also indicate a need for watering.
Leaf Wilting
If the oleander is in need of water, its leaves may begin to wilt. This can be recognized by softened, drooped, or curled leaves. Persistent wilting even in cool temperatures often signals under-watering.
Leaf Color
The color change in oleander's leaves is another important sign. If they're turning yellow or have brown tips, it might indicate a lack of sufficient water.
Stunted Growth
If the oleander exhibits stunted growth, with smaller and fewer flowers, it can be a sign of needed hydration.
Risk Factors
Ignoring these signs and watering oleander too early or too late can lead to several health risks for the plant. Over-watering may cause root rot due to waterlogged soil, whereas under-watering can lead to dehydration, stunted growth, and eventual death of the plant. It's vital to respond to these signals promptly to maintain a healthy oleander.
How Should I Water My Oleander?
Key-Sensitivity and Requirements
Oleander is a drought-tolerant plant that prefers being on the dry side, so it's important not to overwater it. Inefficient water management may cause root rot and other fungal diseases.
Key-Specific Technique-Watering Can
A watering can with a long spout is recommended for watering oleander to ensure water is delivered directly to its root zone and not on the foliage. It's better to water the plant deeply so the filaments in the lower part of the root system can absorb the necessary moisture.
Key-Area to Avoid
Avoid watering the foliage of the oleander as the leaves and stems are susceptible to fungal diseases, which can be exacerbated by moist conditions. Also, try to avoid wetting the crown of the plant, as this can lead to decay.
Key-Specific Technique-Bottom-watering
For potted oleander, bottom-watering can be an effective technique. Place the pot in a tray of water and allow the plant to absorb water from the base. This helps ensure the roots get adequate moisture without oversaturating the surface.
Key-Special Equipment
A moisture meter proves beneficial for watering oleander. It gives an accurate measure of moisture at the root level, helping avoid overwatering or underwatering. These tools are commonly used for plants that have specific watering requirements, like oleander.
Key-Monitor Overwatering Signs
Monitor your oleander for signs of overwatering. These might include yellowing leaves and a spongy feel to the plant's base. If such signs appear, let the plant dry out before watering again.
How Much Water Does Oleander Really Need?
Introduction
Oleander is a species of plant native to Mediterranean regions. It grows well in a variety of soil types, but is particularly adapted to arid conditions and can withstand periods of drought. Understanding its natural habitat will help ensure the plant receives the optimal amount of water.
Optimal Water Quantity
Oleander prefers well-drained soil and does not like to sit in water. When watering, make sure to saturate the root ball and allow excess water to drain out. The quantity of water needed depends on various factors such as pot size, root depth, and plant size. As a general guideline, oleander should be watered thoroughly, allowing the top 1-2 inches of soil to dry out between waterings. For potted oleander plants, this typically means providing approximately 1-2 inches of water per week, but this can vary depending on environmental conditions and the specific plant's needs. It is important to monitor the moisture level of the soil and adjust watering accordingly.
Signs of Proper Hydration
The leaves of a properly hydrated oleander plant will be dark green and glossy. The plant will have sturdy stems and vibrant flowers. A well-watered oleander will also have an overall healthy appearance and show consistent growth. Signs of overwatering can include yellowing or wilting leaves, root rot, or a foul odor. Underwatering may cause the leaves to become dry, brown, or limp.
Risks of Improper Watering
Overwatering can lead to root rot and the death of the plant. It can also create conditions favorable for fungal diseases. Underwatering can cause the plant to become stressed, resulting in stunted growth and a weakened immune system. This can make oleander more susceptible to pest infestations and other diseases. Maintaining the proper water balance is crucial for the overall health and longevity of the plant.

Observe your plants attentively, learning from their growth patterns, and becoming more in tune with their needs as you grow together. Keep a watchful eye on new plants and seedlings, as they are sensitive to both overwatering and underwatering. Shower them with gentle love and attention, fostering their growth and strength. Let the rhythm of your local climate guide your watering habits, adapting your schedule to the changing weather and the needs of your plants.
What Kind of Water is Best for Oleander?
Water Preferences: oleander
likes evenly moist soil but is somewhat drought tolerant, so it's best to allow the top layer of soil to dry out before watering again.
Optimal Water Type: oleander
is not particularly fussy about the type of water it gets, accepting tap water, rainwater, distilled or filtered water.
Chlorine Sensitivity: oleander
is not known to be notably sensitive to chlorine, so regular tap water can generally be used without need for dechlorination.
Fluoride Sensitivity: oleander
is not notably sensitive to fluoride, so fluoridated water sources should not pose a problem.
Mineral Sensitivity: oleander
While this plant is not significantly sensitive to most minerals, excessive amounts of salt in the water can pose a problem, so avoid using softened water that has been treated with salt.
Water Treatments: oleander
Since this plant is not heavily sensitive to typical water contaminants, special water treatments are generally unnecessary, but if your tap water is heavily chlorinated or contains a high level of salts, you might want to consider using filtered or rainwater instead.
Water Temperature: oleander
prefers water at room temperature; avoid using overly hot or cold water.
Additional Notes: oleander
While the type and quality of water is important, the key for oleander is maintaining a balance, not letting the plant sit in waterlogged soil, but also not allowing it to dry out completely.
How Do Oleander's Watering Needs Change with the Seasons?
How to Water oleander in Spring?
Spring is the time when oleander breaks its dormancy and begins new growth. The plant needs enough water to support new foliage and flowers. Maintain moist soil during this season without letting it become waterlogged, allowing the plant to take in the necessary nutrients for growth. However, be cautious not to overwater as it can lead to root rot.
How to Water oleander in Summer?
In summer, oleander is in its active growth phase and requires consistent moisture to thrive. Due to increased sunlight and higher temperatures, water may evaporate quickly. Therefore, ensure the soil remains consistently moist but not soggy. Always check the top inch of the soil before watering, and only water if it feels dry to the touch.
How to Water oleander in Autumn?
As oleander prepares for dormancy in autumn, it requires less water than in active growth periods. This reduction in water corresponds with the plant's decreased growth rate and helps to prevent diseases associated with cooler temperatures and overwatering. Gradually reduce watering frequency, allowing the soil to partly dry out before watering again.
How to Water oleander in Winter?
During winter, oleander is in a dormant state, resulting in minimal growth and, therefore, minimal water requirements. Only water the plant when the soil is dry. Overwatering, coupled with lower light and temperature levels, can potentially harm the plant. Make sure not to let the plant sit in standing water as this could cause the roots to rot.
What Expert Tips Can Enhance Oleander Watering Routine?
Watering Technique
When watering oleander, it is essential to use the right technique to ensure the water reaches the roots effectively. Instead of surface watering, which can lead to shallow root growth, use a soaker hose or drip irrigation system to deliver water directly to the root zone.
Mulching
Applying a layer of organic mulch around the base of oleander can help conserve moisture and regulate soil temperature. Use materials like wood chips or straw to suppress weed growth and reduce evaporation, ultimately reducing the frequency of watering.
Finger Test
To accurately assess oleander's moisture level, don't rely solely on visual cues. Insert your finger into the soil up to the second knuckle. If it feels dry, it's time to water. However, if it feels moist, hold off on watering to avoid over-saturation.
Drainage Assessment
Ensure that the container or planting site for oleander has proper drainage. Check for drainage holes in pots or observe the area for water pooling after rainfall. Poor drainage can lead to waterlogged roots and root rot, so consider amendments or alternative planting locations if drainage is inadequate.
Water Quality
Pay attention to the quality of water used for oleander. Tap water may contain chemicals or excessive salts that could harm the plant over time. If possible, consider using rainwater or distilled water for watering to mitigate any adverse effects on the plant's health.
Drought Tolerance
While oleander is relatively drought tolerant once established, it still requires regular watering during the first few growing seasons. Monitor soil moisture closely during hot and dry periods to ensure the plant receives adequate hydration.
Recovery from Stress
If oleander exhibits signs of stress, such as wilting or yellowing leaves, adjust the watering routine accordingly. Provide supplemental watering during extreme heatwaves or extended periods without rainfall to facilitate recovery and maintain the plant's vitality.
Avoid Overwatering
Overwatering oleander can be detrimental to its health. To prevent overwatering, allow the top inch or two of the soil to dry out between waterings. This promotes deeper root growth and prevents the risk of root rot.
Watch for Warning Signs
Be observant of oleander's leaves and overall appearance to detect signs of both under-watering and over-watering. Drooping or wilting leaves may indicate under-watering, while yellowing leaves or root discoloration could imply over-watering. Adjust watering practices accordingly based on these visual cues.
Summer Rain Adjustments
During periods of frequent rain, it's important to adjust the watering routine for oleander. Monitor soil moisture diligently to prevent waterlogged conditions. Reduce watering frequency and duration if the soil remains consistently wet due to rain.
Heatwave Watering
In the midst of a heatwave or prolonged high temperatures, oleander may require additional watering. Increase the frequency and amount of watering during these hot periods to compensate for the increased water loss through evaporation.
Winter Watering
While oleander is generally more dormant during winter, it still requires periodic watering. Water sparingly but deeply every 4-6 weeks, ensuring the soil has enough time to dry out between waterings. Avoid watering if the ground is frozen or excessively wet.
Pruning Impact
When pruning oleander, consider that excessive foliage removal can lead to increased water stress on the plant. Reduce the watering frequency temporarily after significant pruning to avoid overwatering and give the plant time to adjust to its new foliage-to-root balance.
Considering Hydroponics? How to Manage a Water-Grown Oleander?
Overview
Hydroponics is an innovative cultivation method where plants are grown without soil. For oleander, this method has numerous advantages, such as reduced risk of pests and diseases, controlled nutrient management, and better growth rates from root-zone oxygenation.
Best suited hydroponic system
Oleander thrives best in a deep water culture system. This is because it allows the plant to intake nutrients more efficiently and provides consistent oxygenation, both essential for the plant's rapid growth and bloom.
Nutrient solution
Oleander prefers a balanced nutrient solution with a pH of 5.8-6.2 for optimal growth. Remember to monitor and adjust the pH regularly. Also, change the nutrient solution at least once every two weeks to prevent buildup of salts and toxicities.
Common issues
When growing oleander hydroponically, you may face challenges such as root rot if the water temperature is not properly controlled. Lack of light can also inhibit growth, while inadequate nutrient balance may cause discoloration. To treat these, ensure your setup has a water chiller, adequate light supply, and regular nutrient monitoring.
Monitoring plant health
It's important to frequently monitor your oleander for signs of stress like yellow leaves, which can indicate insufficient nutrients, and wilted or brown leaves, which may signal poor water quality or oxygen levels. This differs from soil-based care, where physical soil conditions typically indicate plant health.
Adjusting hydroponic environment
To cater for oleander’s specific growth stages, maintain a stable water temperature of about 18-22°C for seedling phase, and 20-24°C for vegetative phase and flowering phrase. Also, adjust the light intensity and ph levels as per the stages.
Final tips
Always check your system's water quality and strength of nutrient solution, as these can dramatically affect oleander's health. Practice regular system cleaning to prevent epidemics and ensure optimum nutrient uptake. Lastly, although oleander is drought-resistant in nature, in a hydroponics setup it requires consistent access to water and nutrients to flourish.

Watering Troubleshooting for Oleander
Why are my oleander leaves turning yellow and dropping off?
Yellowing and drooping leaves can be indicators of overwatering, which results in waterlogged and oxygen-starved roots. To solve this issue, adjust your watering schedule by allowing the soil to dry out between watering sessions. If the problem persists, consider improving soil drainage by adding coarse sand or grit to the current mix.
What could be the reason my oleander is developing brown leaf tips?
This is usually a sign of underwatering or low humidity. Despite handling drier conditions, oleander still needs consistent watering. Moderate watering until the water drains out of the pot and maintaining average humidity might help solve this issue. You can also mist the leaves occasionally with water.
Why are my oleander plant's leaves looking limp and wilting despite regular watering?
Limp and wilting leaves can be a symptom of root rot, a disease commonly caused by overwatering and poor drainage. If the roots are waterlogged for too long, decay sets in, preventing proper nutrient uptake. Reduce the watering frequency, ensure good drainage, and consider repotting the plant using fresh, well-draining soil.
Why is my oleander not flowering, despite proper watering and care?
Insufficient watering can be a cause. While oleander can endure drought, it needs regular watering sessions to bloom optimally, besides proper light and temperature. Without sufficient water, the plant may direct its energies towards survival rather than blooming. Increase your watering frequency slightly, but remember not to overwater and to let the soil dry out sufficiently between waterings.
My oleander plants have soft, brown, wilted leaves. What could be the problem?
This could likely be a result of poor drainage leading to waterlogged soil and roots. Oleander prefers well-drained soil, as waterlogging puts the plant under stress causing it to develop soft, brown, and wilted leaves. To rectify this, improve drainage in your pot or garden bed and adjust your watering schedule to avoid overwatering.

Oleander thrives in full sunlight but is sensitive to heat. As a plant commonly grown outdoors with abundant sunlight, it may exhibit subtle symptoms of light deficiency when placed in rooms with suboptimal lighting.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your oleander may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Oleander enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.

Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
The temperature requirements for oleander are relatively moderate, with a preferred temperature range of 59 to 100 ℉ (15 to 38 ℃). It is native to regions with hot, dry summers and mild, wet winters, so it can handle some temperature fluctuation. During the winter, it is important to keep the plant in a location that maintains at least 50 ℉ (10 ℃) to avoid damaging the plant.
Regional wintering strategies
Oleander has some cold tolerance and generally does not require any additional measures when the temperature is above {Tolerable_growing_temperature_min}. However, if the temperature is expected to drop below {Tolerable_growing_temperature_min}, it is necessary to take some temporary measures for cold protection, such as wrapping the plant with plastic film, fabric, or other materials. Once the temperature rises again, the protective measures should be removed promptly.
Important Symptoms
Symptoms of Low Temperature in Oleander
Oleander has moderate tolerance to low temperatures and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may start to droop. In mild cases, they can recover, but in severe cases, the leaves will wilt and eventually fall off.
Solutions
Trim off the frost-damaged parts. Prior to encountering low temperatures again, wrap the plant with materials such as non-woven fabric or cloth, and construct a wind barrier to protect it from the cold wind.
Symptoms of High Temperature in Oleander
During summer, Oleander should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, the leaf tips may become dry and withered, the leaves may curl, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
