The word, lettuce originates from the latin word, lactūca in which the lac word refers to the meaning of milk. Inspired by the secretion of white fluid from the stems, the plant is called prickly lettuce.
Compass plant
Lactuca serriola is known as the compass plant because the leaves are so arranged on the axis as if it is to indicate the cardinal points of the compass.

Garden Use
The flowering herb prickly lettuce is often grown in orchards and plant nurseries. This plant has a weedy, invasive nature, so it is best to grow it in containers or a controlled environment. The yellow and sometimes blue flowers resemble dandelions.

Trivia and Interesting Facts

Though quite different in appearance now, prickly lettuce is the wild version of the plant that eventually became our garden lettuce. It has been cultivated for thousands of years and was associated with the ancient Egyptian god, Min. Greek mythology held that Adonis was laid to rest on a bed of prickly lettuce, so it became considered the food of the dead.

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.

Weed Control About Prickly lettuce

Weeds
Prickly lettuce (Lactuca serriola) is a common annual or biennial herbaceous plant and the closest wild cousin of cultivated lettuce. It is native to Mediterranean areas of Europe, Asia, and North Africa, but it has become naturalized in other regions, mostly in North America, where it is considered an invasive weed of field crops, orchards, and, less significantly, roadsides. Most notably, it infiltrates wheat and reduces the harvesting efficiency, consequently decreasing the price of grain. Belonging to the dandelion family, it has the same plumed seeds as the common dandelion; the wind scatters the seeds far and wide.
How to Control it
The best time to remove weeds is before their flowering and fructification, otherwise controlling them can be very difficult. After they have flowered and fructified, their seeds can spread very fast, and hence, the weeds should be removed more often and precautions should be taken in advance in the following year. Mulching: During the seed stage, covering the soil with sawdust, straw, or black mulches can effectively inhibit seed germination and the growth of seedlings. In the winter or spring, this method is often used to inhibit the seeds in the soil from germinating. If the weeds have already flowered and fructified, then the method can also be used to prevent more seeds from falling into the soil. Pulling out: Wear gloves or use tools to remove weeds before their fructification. If the soil is too dry, then water the soil thoroughly to make it softer, which can help to remove the root systems of the weeds. After that, deep tillage can be adopted to remove bits of weed roots left in the ground. This method works particularly well for weeds that are low-growing or in their seedling stages. Mowing: Mowing weeds before their fructification can effectively control their spread. Especially for annual weeds, frequent mowing can inhibit their growth and fructification, and thus can remove them effectively within the year. Ploughing: Be sure to plough and pull out all roots of perennial weeds before planting. The roots should be discarded, exposed to the sun for a long time, or buried deep. You can also use the roots to make organic fertilizer and compost the weeds. It can be effectively removed with herbicide. Note: When removing weeds, especially those which are toxic, thorny, and have allergenic sap, be sure to wear gloves and avoid direct contact with them. When removing weeds during their bloom time, be sure to wear special masks to prevent pollen allergy.

What is the best way to water my Prickly lettuce?
Not only does the Prickly lettuce have certain preferences regarding how much water it receives, but it also cares deeply about how you provide that water. In fact, if you don't use the proper watering technique, you risk harming your tomatoes. The best way to water Prickly lettuce is to apply the water directly to the soil in a slow and gentle manner. You should not pour all of the water into the soil at once, and you should not do overhead watering for your Prickly lettuce. Although you should water slowly, you should also water deeply to ensure that all of the soil in which your Prickly lettuce grows is sufficiently moist.

What should I do if I water my Prickly lettuce too much or too little?
If you find that you have overwatered your Prickly lettuce and you are concerned about the associated risk of disease, you should intervene immediately. Often the best approach for an overwatered Prickly lettuce is to uproot it from its current growing location. Once the plant is out of the ground, you can allow its roots to dry a bit before planting it in a new growing location. Ensure that the new growing location has soil with good drainage. If you grow in pots, you may also want to move your plant to a pot with more or larger drainage holes. In the case of underwatering, all you will need to do is increase the frequency with which you supply water to your plant.

How often should I water my Prickly lettuce?
Overall, Prickly lettuce requires a significant amount of water throughout the growing season. To meet that high water need, you'll need to water early and often throughout the spring and summer. During the earlier parts of the growing season, you should water your Prickly lettuce about once or twice per week. As the season progresses, you should increase your watering frequency. You may need to water it twice per day or more during summer, depending on the weather. After your Prickly lettuce have gone through their major seasonal growth phases, you can reduce the frequency of your watering to about once per week until the end of the growing season.

How much water does my Prickly lettuce need?
Since Prickly lettuce are incredibly popular, with many professional and amateur gardeners growing them successfully, we have a pretty clear idea of how to care for these plants. That understanding includes specific knowledge about the precise volume of water an average Prickly lettuce should receive. Generally, Prickly lettuce will require about 1 - 1.5 inches of water per week. That volume should be dispersed evenly through your weekly watering. As the weather gets warmer, you may need to supply more water, but in most cases, two inches per week is a good baseline amount.

How can I tell if i'm watering my Prickly lettuce enough?
Underwatering and overwatering can both occur as problems for your Prickly lettuce, and both these problems can manifest with similar symptoms. For example, foliage discoloration and wilting can both result from either overwatering or underwatering. When your Prickly lettuce is underwatered, its leaves will be curling and drooping at the beginning. You will see a bunch of leaves turn less vigorous. Underwatering is also likely to cause stunted growth and poor overall development as both the flowers and this plant require a high amount of water. Overwatering is more likely to lead to disease, including rot. Overwatering may also lead to unpleasant smells rising from your plant's soil. The symptoms of underwatering will show up quicker than overwatering. Overwatering can also be evident in soil conditions. Mainly, if you notice a lot of standing water or waterlogged soils, overwatering is likely to occur.

How should I water my Prickly lettuce through the seasons?
As alluded to above, your Prickly lettuce's water needs will repeatedly change throughout the seasons. During most of spring and summer, you should water your Prickly lettuce about once every week. As the heat of summer arrives, you should plan to increase your watering frequency to once or twice per day. In the late summer and fall, towards the end of the harvest period, you can reduce your watering frequency to about once per week. After harvest has ended, you can cease watering as your Prickly lettuce has reached the end of its life cycle and will require no further soil moisture.
The maintenance schedule of Prickly lettuce will require you to alter the amount of water you provide depending on the plant's current growth stage. Early on, especially if you grow your Prickly lettuce from seeds, you'll need to provide water often enough to maintain consistent soil moisture, which encourages root development. When the plant becomes old enough to produce flowers, it will likely need even more water. During the fruit development growth stage, your Prickly lettuce will likely need the most water out of any growth period, at times requiring water more than twice per day. Following that phase, the water needs of Prickly lettuce will decline significantly.

What's the difference between watering Prickly lettuce indoors and outdoors?
Whether you grow Prickly lettuce indoors or outdoors can also play a role in how you water them. Prickly lettuce that grows outdoors may receive water from natural rainfall, which will reduce the amount of supplemental water you should supply. However, it is incredibly rare for rainfall to adequately replace your watering entirely. Plants that grow indoors, along with any Prickly lettuce that grows in a container, will need to be watered more frequently than those that grow in the ground outdoors. If you choose this route, please make sure that the plant gets enough water by checking the soil moisture within your pot often to keep your Prickly lettuce healthy.

More Info on Prickly Lettuce Growth and Care

Basic Care Guide
Explore More
Water
Every week
Prickly lettuce hails from the dry, well-drained soils of Europe, Asia and North Africa, a region characterized by a temperate climate with relatively low annual rainfall. Speaking to its watering needs, this adaptability to dry conditions means prickly lettuce has developed a preference for less frequent watering, as excessive moisture can lead to root rot. Close observation of topsoil dryness, rather than timetable adherence, is the best guide when watering prickly lettuce.
Watering Techniques
Lighting
Full sun
Prickly lettuce thrives when it receives sunlight for the majority of the day, though it tolerates periods of less intensive sun exposure. Its ability to grow in this range of sun exposure is linked to its origin habitat. However, extended periods of inadequate light can harm its growth, much like excessive sun exposure can affect its health.
Best Sunlight Practices
Temperature
0 - 38 ℃
Prickly lettuce is indigenous to environments where the temperature fluctuates between 68 to 95 °F (20 to 35 ℃). This plant highly favors temperatures within this range, so maintaining these conditions, particularly during season changes, should promote healthy growth. If necessary, seasonal adjustments in temperature should be conducted.
Temp for Healthy Growth
Transplant
1-2 feet
Transplant prickly lettuce during the delightful days of mid-spring to early summer, ensuring plentiful growth. Choose a sunny location with well-draining soil for best results. Remember to be gentle when handling prickly lettuce, as they can be quite delicate.
Transplant Techniques
Feng shui direction
South
The prickly lettuce plant is believed to embody a resonating energy in Feng Shui, particularly suited for a southern facing direction. The plant's prickly texture entails the presence of fire element, which aligns well with the south, the domain of fire in the traditional bagua. This association is seen as an enhancement of prosperity and recognition. Nevertheless, interpretation can vary depending on individual perceptions of Feng Shui principles.

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.

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.

Weed Control About Prickly lettuce

weed
Weeds
Prickly lettuce (Lactuca serriola) is a common annual or biennial herbaceous plant and the closest wild cousin of cultivated lettuce. It is native to Mediterranean areas of Europe, Asia, and North Africa, but it has become naturalized in other regions, mostly in North America, where it is considered an invasive weed of field crops, orchards, and, less significantly, roadsides. Most notably, it infiltrates wheat and reduces the harvesting efficiency, consequently decreasing the price of grain. Belonging to the dandelion family, it has the same plumed seeds as the common dandelion; the wind scatters the seeds far and wide.
How to Control it
The best time to remove weeds is before their flowering and fructification, otherwise controlling them can be very difficult. After they have flowered and fructified, their seeds can spread very fast, and hence, the weeds should be removed more often and precautions should be taken in advance in the following year. Mulching: During the seed stage, covering the soil with sawdust, straw, or black mulches can effectively inhibit seed germination and the growth of seedlings. In the winter or spring, this method is often used to inhibit the seeds in the soil from germinating. If the weeds have already flowered and fructified, then the method can also be used to prevent more seeds from falling into the soil. Pulling out: Wear gloves or use tools to remove weeds before their fructification. If the soil is too dry, then water the soil thoroughly to make it softer, which can help to remove the root systems of the weeds. After that, deep tillage can be adopted to remove bits of weed roots left in the ground. This method works particularly well for weeds that are low-growing or in their seedling stages. Mowing: Mowing weeds before their fructification can effectively control their spread. Especially for annual weeds, frequent mowing can inhibit their growth and fructification, and thus can remove them effectively within the year. Ploughing: Be sure to plough and pull out all roots of perennial weeds before planting. The roots should be discarded, exposed to the sun for a long time, or buried deep. You can also use the roots to make organic fertilizer and compost the weeds. It can be effectively removed with herbicide. Note: When removing weeds, especially those which are toxic, thorny, and have allergenic sap, be sure to wear gloves and avoid direct contact with them. When removing weeds during their bloom time, be sure to wear special masks to prevent pollen allergy.

Prickly Lettuce Watering Instructions
Prickly lettuce hails from the dry, well-drained soils of Europe, Asia and North Africa, a region characterized by a temperate climate with relatively low annual rainfall. Speaking to its watering needs, this adaptability to dry conditions means prickly lettuce has developed a preference for less frequent watering, as excessive moisture can lead to root rot. Close observation of topsoil dryness, rather than timetable adherence, is the best guide when watering prickly lettuce.
When Should I Water My Prickly Lettuce?
Introduction
Proper and timely watering plays a crucial role in maintaining the overall health and development of the prickly lettuce. It contributes to its optimal growth, vibrant flower production, and resistance against diseases. Therefore, understanding the appropriate signals indicating when the plant should be watered is essential.
Soil Dryness
A clear sign of when prickly lettuce needs water is the dryness of the soil. This can be checked by touching the soil around the plant base. If the top 1 to 2 inches of soil is dry to the touch, this means the plant most likely requires watering.
Leaf Condition
The condition of the leaves of prickly lettuce can also be a reliable indicator for watering necessities. If the leaves appear wilted, lackluster, or begin to lose their vibrant color tending to fade or yellow, these are indicative of the plant being under-watered.
Watering Frequency
The frequency of watering prickly lettuce can be determined by its size and growth stage. Small or newly planted prickly lettuce generally require more frequent watering compared to established ones. Watering frequency can vary with environmental factors such as temperature and sun exposure.
Soil Moisture Level
Checking the soil moisture level can provide insights into whether prickly lettuce requires watering. Insert a finger into the soil about 2 inches deep. If the soil feels dry at that depth, it is time to water the plant. If the soil is still moist, you can wait to water.
Lack of Transpiration
Another sign that prickly lettuce needs watering is a lack of transpiration. Transpiration is the process by which plants release water vapor through their leaves. If prickly lettuce is not transpiring and the leaves are not actively emitting moisture, it may be an indication that the plant is experiencing water stress and needs watering.
Early Watering Risks
Watering prickly lettuce too early, when the soil is still moist, could risk root rot, fungus infestation, and other root diseases due to over-watering.
Late Watering Risks
Watering prickly lettuce too late, when it has been excessively dry for an extended period, could risk temporary wilting and might stunt the plant's growth. In extreme conditions, it can lead to plant death due to dehydration.
Conclusion
Understanding these signs is critical to effectively manage the watering schedule for the prickly lettuce. Proper water management not only encourages its growth and flowering but also prolongs its lifespan and maintains plant health.
How Should I Water My Prickly Lettuce?
Watering Requirements
Lactuca serriola, has specific watering needs and sensitivities that should be considered for optimal hydration.
Watering Technique
Bottom-watering is an effective method for watering Lactuca serriola. This technique involves placing the plant pot in a tray or saucer filled with water and allowing the roots to absorb water from the bottom up. It helps to prevent excess moisture on the foliage and minimize the risk of fungal diseases.
Watering Can Type
When using a watering can, it is recommended to choose one with a narrow spout to direct the water flow directly to the base of Lactuca serriola. This helps to avoid wetting the foliage excessively and promotes targeted hydration at the root level.
How Much Water Does Prickly Lettuce Really Need?
Introduction
Prickly lettuce's hydration needs are influenced by its natural habitat, which is often roadsides, fields, and waste areas, which typically do not hold water for long. This denotes that prickly lettuce is fairly drought-tolerant and can survive on minimal water input.
Optimal Water Quantity
Prickly lettuce's water requirement is moderate to low due to its survivability in low water areas. Its root depth and plant size dictate its water necessity. A mature prickly lettuce with deep-set roots in a large pot would require a higher amount of water as compared to a sapling in a smaller pot. However, you should avoid overly wet soil and ensure proper drainage to prevent saturating the plant's roots.
Signs and Conditions of Proper Watering
Prickly lettuce being drought-tolerant, is more forgiving to under-watering than over-watering. Indications of correct watering include firm, robust leaves, and strong stem. If the plant's leaves start to wilt or turn yellow, it may be an indication of under-watering or over-watering respectively. Additionally, checking the moisture consistency of the topsoil can be effective in knowing if the plant needs watering.
Effects of Over or Under Watering
Under-watering prickly lettuce might eventually lead it to wilt and stunt its growth, while over-watering could result in root rot and the yellowing of leaves. Both extremes can harm the plant's health and vitality.
Plant-Specific Advice
Given prickly lettuce's natural predisposition to drought-like conditions, it is wise to err on the side of under-watering then over-watering. Furthermore, a well-drained soil mix can prove to be helpful to avoid too much water retention.

What Kind of Water is Best for Prickly Lettuce?
Ideal Water Type
Prickly lettuce prefers rainwater or distilled water as these are free from chemicals and dissolved minerals which could potentially harm the plant.
Tap Water Suitability
While tap water can be used for prickly lettuce, it may contain chlorine, fluoride, or other minerals that could be harmful. Be aware of the quality and content of your tap water before choosing this option.
Water Treatments
Prickly lettuce might not directly react to chlorine or fluoride. However, to be safe, letting tap water sit out for at least 24 hours can allow chlorine to evaporate. Thus, this can be beneficial for the health of your prickly lettuce.
Sensitivity to Contaminants
Prickly lettuce does not have specific sensitivities to common water contaminants. However, a general rule of thumb for most plants, including prickly lettuce, is to avoid using water that has a high salt or mineral content. These can build up in the soil and cause damage over time.
Water Temperature Preferences
Prickly lettuce does not have strict temperature preferences; however, it naturally grows in cooler climates. Therefore, use cold to lukewarm water, avoiding hot or warm water which might stress the plant.
Watering Conditions and Schedule
Prickly lettuce prefer well-drained soils, hence avoid over-watering. The soil should be allowed to dry out between watering intervals.
How Do Prickly Lettuce's Watering Needs Change with the Seasons?
How to Water prickly lettuce in Spring?
During spring, prickly lettuce experiences its active growth phase. It is essential to maintain consistent soil moisture to support healthy growth. Water regularly, keeping the soil evenly moist.
How to Water prickly lettuce in Summer?
In summer, prickly lettuce may enter a drought period where it undergoes natural dormancy to conserve energy. Reduce watering frequency, allowing the soil to dry slightly between waterings.
How to Water prickly lettuce in Autumn?
During autumn, prickly lettuce prepares for winter dormancy. Gradually decrease the frequency of watering as the plant enters its dormant phase. Ensure the soil remains lightly moist.
How to Water prickly lettuce in Winter?
In winter, prickly lettuce experiences its dormant period. Water sparingly as the plant requires minimal moisture during this time. Allow the topsoil to dry out between waterings.
What Expert Tips Can Enhance Prickly Lettuce Watering Routine?
Moisture Meter
Using a moisture meter can help assess prickly lettuce's deeper soil moisture needs and prevent over or under-watering. This plant prefers its soil to be mostly dry before the next watering, and a meter can effectively measure this.
Watering Time
Watering prickly lettuce early in the morning allows the water to penetrate the soil thoroughly before the high evaporation rates of mid-day. It also helps prevent fungal diseases by minimizing the plant's exposure to dampness.
Common Misconception
One common misconception when watering prickly lettuce is that it needs constant watering. However, prickly lettuce is a drought-tolerant plant that actually prefers dry conditions. Over-watering can lead to root rot and other diseases. It's important to let the soil dry out slightly between waterings.
Signs of Thirst or Over-watering
To determine if prickly lettuce needs watering, check the soil moisture. Stick your finger or a moisture meter about 2-3 inches into the soil. If it feels dry at that depth, it's time to water. However, if the soil feels consistently wet and the plant looks droopy or has yellowing leaves, it may be over-watered. Adjust watering accordingly.
Adjusting Watering in Special Conditions
During a heatwave, prickly lettuce may require more frequent watering as the higher temperatures increase evaporation. However, be cautious not to over-water as this can cause root rot. In extended rainy periods, prickly lettuce may not need additional watering unless the soil becomes waterlogged. If the plant appears stressed, check the soil moisture before watering.
Soil Assessment
Assessing soil moisture beyond the surface level is important for prickly lettuce. Use a trowel or garden spade to gently dig a few inches into the soil near the plant's base. This will give a clearer indication of moisture levels. The soil should feel dry or only slightly moist before the next watering.
Watering Methods
To prevent water stress, it's best to water prickly lettuce deeply and thoroughly. Slowly apply water at the base of the plant, allowing it to soak into the soil rather than spraying the leaves. This encourages deep root growth and also minimizes fungal diseases.
Container Tips
If growing prickly lettuce in a container, ensure it has proper drainage holes to allow excess water to escape. Avoid letting the pot sit in a saucer of water, as it can lead to root rot. Check the soil moisture frequently as containers may dry out faster than plants in the ground.
Drought Management
When facing drought conditions, prickly lettuce has adaptive mechanisms to survive. It may exhibit wilting or drooping leaves, which is a natural response to conserve water. Inspect the soil moisture and only water when necessary, following the dryness indicators mentioned earlier.
Considering Hydroponics? How to Manage a Water-Grown Prickly Lettuce?
Overview
Hydroponics is a method of growing plants without soil, using mineral nutrient solutions in a water medium. For prickly lettuce, this method can be efficient, yielding a controllable environment that allows for continuous harvesting and greater yield compared to traditional soil-based cultivation.
Ideal Hydroponic System
Prickly lettuce is adaptable to many different hydroponic systems, nonetheless, the Deep Water Culture (DWC) system is the most suitable for this plant. This system allows for prickly lettuce's long, strong roots to grow unhindered directly into nutrient-dense water.
Nutrient Solution
Prickly lettuce prefers a balanced nutrient solution with pH of 5.8-6.2 for optimal growth. Nutrient solutions should be changed every 2 to 3 weeks, and constant monitoring is necessary to ensure nutrient concentrations remain within acceptable ranges.
Challenges
Common challenges when growing prickly lettuce hydroponically include root rot, due to the extended exposure to water, and nutrient imbalances which can occur if the nutrient solution isn't managed properly. Additionally, prickly lettuce also has considerable light needs, requiring around 10-12 hours of light per day to thrive.
Plant Monitoring
The health of hydroponically grown prickly lettuce can be tracked by checking the leaf color and root health. Leaf discoloration can indicate nutrient deficiencies while roots turning brown or slimy indicates possible root rot. In both cases, quick adjustments to the hydroponic system should be made to prevent further stress or damage to the plant.
Adjusting Hydroponic Environment
As prickly lettuce progresses through its growth stages from seedling, vegetative, to flowering, its nutrient and light requirements may change. In the seedling stage, maintain a humidity of about 70%. As it develops into vegetative stage, gradually decrease the humidity to about 40%. During the flowering stage, the plant could need a bit more phosphorous; therefore, phosphate-rich solutions might be necessary. Light exposure should be adjusted as needed across the life cycle.
Conclusion
Overall, growing prickly lettuce hydroponically can be a successful endeavor if the right hydroponic system is chosen, nutrient solutions are properly managed, vigilant monitoring is maintained, and necessary adjustments are made in accordance with the plant's growth needs. Hydroponics offers great potential for prickly lettuce cultivation, promising higher yields and better control of the growing environment.

How Do You Remove Prickly Lettuce from the Soil?
- From Ground: Water the prickly lettuce plant to dampen the soil. Dig a wide trench around the plant using a shovel or spade, ensuring the plant's root ball remains intact. Carefully work the spade under the root ball to lift the plant from its original location.
- From Pot: Water the prickly lettuce plant thoroughly to help the soil loosen from the pot walls. Position your fingers on the top of the soil, with the plant stem between your fingers. Hold the pot with the other hand and gently turn it upside down. Slightly tap the bottom of the pot to release the plant, keeping the root ball intact.
- From Seedling Tray: Water the prickly lettuce seedlings to dampen the soil. Use a trowel, spoon, or your fingers to gently lift the seedling from the tray, ensuring you do not damage the roots. Handle the seedling by its leaves or root ball, not its stem.
