What’s the best method to water Smooth hydrangea?
Soaker hoses can be the best method to keep the moisture from the leaves and flowers. These methods are great when you want more efficient water delivery at the very base of the plant without needing to get the entire foliage wet.
Lay the hose around the plant, leave it on for about 30 to 45 minutes and wait until the soil is moist but not too wet. Hook your regular hose to this, and cover with mulch. Others may use drip feeders to retain moisture throughout the day.
When planted in pots, you need to water the Smooth hydrangea using a watering can. Wait until you see that the water is dripping down the pots at the bottom part. The portable cans can help you reach the soil and let the water penetrate the roots deeply so they can grow better.

What should I do if I water Smooth hydrangea too much/too little?
If you overwatered Smooth hydrangea, you might want to take a few steps back and prevent further damage. Smooth hydrangea is hardy, so they have a higher chance of surviving. Give the plant a chance to dry everything out and stop watering it. The plants don’t tolerate their roots sitting in water for longer, so aerating can help.
Some of the symptoms of an overwatered plant will be premature falling of yellow leaves. You might also see fewer flowers and misshapen buds. In more serious cases, this can result in wilted and brown leaves. Long-term overwatering can result in root rot.
The symptoms of underwatering can be similar. Wilting Smooth hydrangea can be a sign of underwatering. Feel the earth by sticking your finger into the soil, and if it’s too dry, then this is a sign of dehydration. Too little watering can also happen, so you might want to add some in the evening. Always check the soil for dryness and follow the regular schedule of watering in the morning.

How often should I water Smooth hydrangea?
It’s best to water the Smooth hydrangea deeply two to three times a week. And you should water it more often if you live in a hot climate. Its water needs are average, and it needs moist but well-drained soil.
A good rule of thumb is to get a feel of the soil. It might be the right time to water your plant if you notice that it’s about 2-4 inches dry.
Water it 1-2x a week if it’s planted outdoors. Know that it’s getting more moisture outside, watering less with the help of rainwater is ideal.
Read More more
How much water does my Smooth hydrangea need?
The amount of water needed can vary. There are a lot of factors to consider, such as the weather in the area, the amount of shade, and the species. The Smooth hydrangea you’ve just recently planted will need more water than the established ones. A can of water each week can be ample for Smooth hydrangea, especially if they are in the growing season and when they are grown in pots.
When outdoors, you need to measure the amount of rain they are receiving with the help of moisture meters. When the soil is dry, water them thoroughly with a sprinkler. It’s best to water less often but thoroughly with the Smooth hydrangea to ensure they are getting the adequate moisture they need.
Read More more
Why is watering my Smooth hydrangea important?
Regardless of the types of the plant that you’re growing, it’s important to know its watering needs so that they will grow well. Smooth hydrangea needs a lot of water and can quickly wilt without the right moisture.
They require moist soil but make sure that the ground is well-drained. Smooth hydrangea doesn’t want wet feet since they tend to get root rot. Overwatering can also lead to slow production of flowers and stunted growth, which can also be a problem seen with underwatering.
Read More more
How can I ensure that i'm watering my Smooth hydrangea adequately?
It's best to water the Smooth hydrangea in the early morning to prevent it from wilting. It may be unable to handle the heat and can show signs of wilting in the afternoon. Make sure to apply a thick layer of mulch to keep the soil cool and retain moisture.
Once it feels the coolness of the evening, it will go back to its usual glow. Always water deeply and be consistent with the moisture. However, remember that it’s better to experience a slight wilting in the afternoon than to over-water them.
Read More more
Should I adjust the frequency of watering my Smooth hydrangea according to different seasons or climate?
When watering during the summer, it’s important to take the environment into consideration. These plants enjoy the early morning sun but not much of the midday glare since they can dry out too quickly.
It’s best to start planting these species in spring or autumn. Provide ample water, especially when you notice that the soil is dry during the summer. Don’t water the plants during the winter as they will enter a period of dormancy.
Fill the pot up to the rim, let the water soak, and run out of the drainage hole. Always water when the soil feels dry and if you have windy and hot weather. The plant supports a lot of big blooms, and they need ample water to maintain them.
Read More more
Should I change the watering frequency during different growing stages of my Smooth hydrangea?
During the growing season, it’s best to water this at a rate of 1 inch when it’s just growing. This should be done 3x per week. When growing in pots, you need to have one with a diameter of at least 18 inches. A non-porous one can help hold consistent levels of moisture.
An established plant does not need watering as much as one in the early phase of growth. They can be watered twice a week but always check the soil to be sure. Just make sure that there will be no waterlogging that occurs.
The plants might experience transplant shock when they are just newly planted. Just water until the depth of the moisture reaches out to 10 inches beneath the surface. Help the roots become more established during the dry, hot weather by checking the soil frequently.
Read More more
What should I be careful with when I water my Smooth hydrangea in different seasons, climates, or during different growing periods?
Overall, the Smooth hydrangea loves water and should be provided with enough to keep it hydrated.
Be careful not to overwater and never use cold water with them during the winter. They enter a dormancy period and they barely need water to survive.
In the spring, planting should be done where they will be given enough time to grow. Water more when they are young and make sure to give them enough mulch to keep the soil moist.
During the summer, just make sure that the soil is moist. Overwatering can result in a lack of blooms, but a heavy soaking can be done once a day whenever the soil needs this. For 3x a week, ensure water in the early mornings or afternoons.
The ones on the balcony or gardens should be watered generously during the summer months. This is because the water can evaporate quickly.
Read More more
Should I water Smooth hydrangea differently when I plant it indoors but not outdoors?
The Smooth hydrangea that is grown outdoors doesn’t generally need a lot of water compared to the one grown indoors. This species absorbs the water quickly, so watering can be done twice a week. When you grow Smooth hydrangea in partial shades, you generally encourage moisture retention and prevent the drying winds from wilting them. It’s best to keep the water away from the flowers as this can lead to gray mold.
The Smooth hydrangeaed indoors can be watered at least 2x a week or more when they are just in the growing phase to help the roots become more established.

Name story

Smooth hydrangea
As compared to any common hydrangea, the flowers are denser in this plant. This makes the flower ball look full and smooth like a snowball, so it is called smooth hydrangea.
Sevenbark
The stem bark has a peculiar tendency to peel off in several successive thin layers with different colors, so the common name is called sevenbark.

Usages

Garden Use
Smooth hydrangea is a flowering shrub that is sometimes grown ornamentally for its unusually shaped green-white flowers. This plant spreads rapidly and is, therefore, a good choice of ground cover plant. It also makes for a great flowering hedge and looks great in mixed borders. Azaleas grow well with hydrangeas since they bloom early, offering garden color before smooth hydrangea flowers.

Trivia and Interesting Facts

Although most hydrangeas are native to Asia, smooth hydrangea (Hydrangea arborescens) was discovered growing natively in North America by a woman on horseback in 1910. She famously found in growing on her ride, and came back later to dig up the flower. She planted it in her yard, where it continued to grow, and showed it to all of her friends. Smooth hydrangea is considered one of the most underrated hydrangeas.

Flowers may wither for a variety of reasons.
Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
Leaf beetles
Leaf beetles Leaf beetles
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Wilting after blooming
Flowers may wither for a variety of reasons.
Overview
Overview
Wilting after blooming is sometimes a natural aging process of the flower, while other times it may indicate a problem. Orchids, for example, can bloom for anywhere from two weeks to three months, so wilting after a few days signals a problem for most varieties. This can happen to virtually any ornamental flowering plant, but those with shallow roots and limited tolerance for drought, full sun, and low humidity are more susceptible.
This is a common problem, and often has an easy fix. Sometimes, however, it is the result of more serious causes such as pests or disease of the root system.
Symptom Analysis
Symptom Analysis
  • At first, flowers may look a little limp.
  • Petals may start to appear dried out and turn brown.
  • Eventually they may drop off the plant all together.
Disease Cause
Disease Cause
Wilting blooms can be a sign of an unhealthy root system. Any condition that prevents the plant from absorbing enough water and nutrition can result in wilting blooms and sometimes other symptoms. If the plant doesn’t have enough water, it cannot maintain appropriate pressure within stems, leaves, and blooms, causing them to wilt.
This can result from physical damage – for example from root breakage during re-potting or attack by insects like cutworms. If you recently re-potted your plant, physical damage to the roots is a likely cause. If you see insects, they may be eating leaves, roots, or flowers. Fungal infections can also cause root rot and damage, preventing water and nutrient uptake.
Finally, wilting blooms can result simply from age. If no other symptoms are visible, it may simply signal the natural end of the flower’s lifespan. If it seems premature, this may be caused by environmental factors: water, humidity, light, or stress. Under-watering is a common cause. Similarly, plants adapted to high humidity dry out easily when humidity is low, like during winter or in dry climates. Too much light can also stress plants that need shade, causing blooms to wilt.

Leaf beetles
plant poor
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.

Smooth hydrangea and Their Toxicity

* 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.
Toxic to Dogs
Toxic to Dogs
Smooth hydrangeas are mildly poisonous to dogs. Their leaves, flowers, and buds all contain the toxic substance, with the highest concentrations being found in flowers and young leaves. Vomiting and diarrhea are the most common symptoms of smooth hydrangea ingestion. Thankfully, severe poisoning cases are rare - this toxin must be consumed in very large amounts to be fatal.
Toxic to Cats
Toxic to Cats
The smooth hydrangea (Hydrangea arborescens) is moderately poisonous to cats. The leaves and all parts of the flower contain the toxin. When eaten in sufficient amounts, they can cause nausea, diarrhea, vomiting, labored breathing, lethargy, and dermatitis. Small cats and kittens are at the highest risk of serious illness. Consult your veterinarian if your cat has eaten 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.

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.

Name story

Smooth hydrangea
As compared to any common hydrangea, the flowers are denser in this plant. This makes the flower ball look full and smooth like a snowball, so it is called smooth hydrangea.
Sevenbark
The stem bark has a peculiar tendency to peel off in several successive thin layers with different colors, so the common name is called sevenbark.

Usages

Garden Use
Smooth hydrangea is a flowering shrub that is sometimes grown ornamentally for its unusually shaped green-white flowers. This plant spreads rapidly and is, therefore, a good choice of ground cover plant. It also makes for a great flowering hedge and looks great in mixed borders. Azaleas grow well with hydrangeas since they bloom early, offering garden color before smooth hydrangea flowers.

Trivia and Interesting Facts

Although most hydrangeas are native to Asia, smooth hydrangea (Hydrangea arborescens) was discovered growing natively in North America by a woman on horseback in 1910. She famously found in growing on her ride, and came back later to dig up the flower. She planted it in her yard, where it continued to grow, and showed it to all of her friends. Smooth hydrangea is considered one of the most underrated hydrangeas.

Flowers may wither for a variety of reasons.
Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.

Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Wilting after blooming

Wilting after blooming
Flowers may wither for a variety of reasons.
Overview
Overview
Wilting after blooming is sometimes a natural aging process of the flower, while other times it may indicate a problem. Orchids, for example, can bloom for anywhere from two weeks to three months, so wilting after a few days signals a problem for most varieties. This can happen to virtually any ornamental flowering plant, but those with shallow roots and limited tolerance for drought, full sun, and low humidity are more susceptible.
This is a common problem, and often has an easy fix. Sometimes, however, it is the result of more serious causes such as pests or disease of the root system.
Symptom Analysis
Symptom Analysis
  • At first, flowers may look a little limp.
  • Petals may start to appear dried out and turn brown.
  • Eventually they may drop off the plant all together.
Disease Cause
Disease Cause
Wilting blooms can be a sign of an unhealthy root system. Any condition that prevents the plant from absorbing enough water and nutrition can result in wilting blooms and sometimes other symptoms. If the plant doesn’t have enough water, it cannot maintain appropriate pressure within stems, leaves, and blooms, causing them to wilt.
This can result from physical damage – for example from root breakage during re-potting or attack by insects like cutworms. If you recently re-potted your plant, physical damage to the roots is a likely cause. If you see insects, they may be eating leaves, roots, or flowers. Fungal infections can also cause root rot and damage, preventing water and nutrient uptake.
Finally, wilting blooms can result simply from age. If no other symptoms are visible, it may simply signal the natural end of the flower’s lifespan. If it seems premature, this may be caused by environmental factors: water, humidity, light, or stress. Under-watering is a common cause. Similarly, plants adapted to high humidity dry out easily when humidity is low, like during winter or in dry climates. Too much light can also stress plants that need shade, causing blooms to wilt.
Solutions
Solutions
  • Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water.
  • Water according to recommendations for each plant's species.
  • Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too.
  • Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants.
  • Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
Prevention
Prevention
  • Read up on moisture, light, and soil type preferences for each plant to avoid underwatering, incorrect light levels, or other conditions that can cause wilting blooms.
  • Avoid re-potting during the flowering period. This causes additional stress on the plants because they need to repair root damage and adapt to the new micro-environment, all of which can result in wilting.
  • One other potential cause is ethylene gas, a plant hormone related to ripening. Some fruits and vegetables emit ethylene, especially bananas. Apples, grapes, melons, avocados, and potatoes can also give it off, so keep flowering plants away from fresh produce.

Leaf beetles

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
Prevention
To prevent infestations of leaf beetles, follow these practices.
  1. Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
  2. Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
  3. Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
  4. Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Smooth hydrangea and Their Toxicity

* 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.
Toxic to Dogs
Smooth hydrangeas are mildly poisonous to dogs. Their leaves, flowers, and buds all contain the toxic substance, with the highest concentrations being found in flowers and young leaves. Vomiting and diarrhea are the most common symptoms of smooth hydrangea ingestion. Thankfully, severe poisoning cases are rare - this toxin must be consumed in very large amounts to be fatal.
Toxic to Cats
The smooth hydrangea (Hydrangea arborescens) is moderately poisonous to cats. The leaves and all parts of the flower contain the toxin. When eaten in sufficient amounts, they can cause nausea, diarrhea, vomiting, labored breathing, lethargy, and dermatitis. Small cats and kittens are at the highest risk of serious illness. Consult your veterinarian if your cat has eaten any part of this plant.

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.

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.

Smooth hydrangea thrives with a balanced nutrient solution containing a ratio of macronutrients (N, P, K), micronutrients (Fe, Mn, Zn, etc.), and secondary nutrients (Ca, Mg, S). Maintain a nutrient concentration of around 800-1200 ppm (parts per million) for vigorous growth. Additionally, the pH of the nutrient solution should be maintained between 5.8 and 6.2 to ensure proper nutrient availability.
Nutrient Change Frequency
It is recommended to change the nutrient solution in a hydroponic system containing smooth hydrangea every 1-2 weeks. This helps prevent nutrient imbalances, buildup of salts, and promotes healthy root growth.
Challenges and Common Issues
When growing smooth hydrangea hydroponically, root rot can be a common problem. To prevent this, ensure good oxygenation of the root zone by using air stones or diffusers. Nutrient imbalances can also occur if the solution is not properly balanced or if the pH is incorrect. Regular monitoring and adjustment of the nutrient solution can help overcome these challenges. Additionally, smooth hydrangea requires adequate light for photosynthesis, so it's important to provide sufficient artificial lighting if natural light is insufficient.
Monitoring Plant Health
Monitor smooth hydrangea closely for signs of stress, such as wilting or yellowing leaves, which may indicate nutrient deficiencies or imbalances. Pay attention to changes in leaf color or texture, as well as overall plant growth. Regularly check the root system for any signs of rot or discoloration. If detected, take immediate action to prevent further damage.
Adjusting Hydroponic Environment
As smooth hydrangea progresses through different growth stages, you may need to adjust the hydroponic environment. For example, during the vegetative stage, provide higher nitrogen levels to promote leafy growth. In the flowering stage, adjust the nutrient solution to encourage blossom development. Additionally, adjust lighting duration and intensity to mimic natural day and night cycles.

Step-by-Step Guide for Transplanting Smooth Hydrangea
Site Selection
Choose a location with appropriate sunlight and space for your smooth hydrangea plant to grow to its mature size.
Digging
Dig a hole twice as wide and just as deep as the root ball of your smooth hydrangea plant. This ensures the roots have enough space to spread out and establish themselves.
Soil Amendment
Add a layer of compost or organic matter to the bottom of the hole, about 1-2 inches thick. Mix this in with the native soil to promote better root growth.
Plant Placement
Gently lower the smooth hydrangea into the planting hole, making sure the plant is level with the surrounding soil. Do not bury the crown (where stems meet the roots) below soil level.
Filling the Hole
Carefully back-fill the hole with the amended soil mixture, pressing gently to remove any air pockets.
Watering
Thoroughly water the smooth hydrangea plant to settle the soil and help establish the roots.
Mulching
Apply a layer of mulch (about 2-3 inches thick) around the base of the smooth hydrangea, keeping the mulch a few inches away from the stem. This helps retain moisture and suppress weed growth.
How Do You Care For Smooth Hydrangea After Transplanting?
Watering
Keep the soil around the smooth hydrangea consistently moist, but not soggy, for the first few weeks after transplanting to help establish strong roots.
Pruning
Trim back any damaged or broken stems after transplanting to promote healthy growth.
Monitoring
Watch for signs of stress, such as wilting or yellowing leaves, and address potential issues promptly. Be patient, as it may take a few weeks for your smooth hydrangea to bounce back from transplanting shock.
Frost Protection
If transplanting late in the season, be prepared to protect your smooth hydrangea from frost or freezing temperatures with a frost cloth or other protective covering.
