Are Haworthias poisonous or safe?

Haworthias are known for their varieties and colorful appearance, and they are also safe near animals.

Though ingesting or handling it might cause stomach issues or rashes, that won’t be dangerous or deadly.

According to the well-known American Society for the Prevention of Cruelty to Animals (ASPCA), Haworthias are documented as non-toxic plants.

Many gardeners grow Haworthia instead of Aloe Vera due to their love for the latter’s appearance.

Some Haworthia varieties look like Aloe Veras, but Aloe is toxic to pets. Therefore, people prefer the non-toxic Haworthia.

However, the sap of Haworthias can cause slight rashes when they come in contact with the skin.

It will go away after some time. 

Are Haworthias poisonous to cats and dogs?

Since many people possess cats and dogs, this question is one of the most frequently asked questions.

Many people consider succulents are poisonous.

But Haworthias are not toxic to cats and dogs.

Not much will happen if they mistakenly eat it up.

Moreover, pets like cats and dogs are quite conscious about not harming their health.

They try to stay careful and sniff well before ingesting any food.

So there is less chance of them eating Haworthias.

Slight vomiting or nothing can happen.

It also depends on their health conditions.

They might feel a little uneasy due to the taste.

The problem is with the puppies and kittens.

Since they are yet to learn about being conscious about their health, they might try to taste them out of curiosity.

Are Haworthias toxic to rabbits and other small animals?

As I said earlier, no harm will happen if animals feed on them.

The same goes for small animals like rabbits.

Rabbits mostly like to munch whatever they find when hungry.

I am not sure about the results after rabbits eat them, but I am pretty sure that your garden bed will turn into a mess.

So, protect your bed with a fence barrier.

They may have a feeling of disgust due to the taste of the sap.

After that, they will never go back near them.

As I mentioned earlier, Haworthias are not considered toxic to dogs, cats, rabbits, or other living beings.

So, you don’t need to worry. If anything happens, visit a vet.

Are Haworthias poisonous to human beings?

Haworthia soil needs

Many people claim Haworthias to be safe around both pets and humans. 

However, it is better not to consume and keep them out of the children’s reach.

If Haworthias are outside, create a fence so that children won’t enter the garden.

If you have kept Haworthia indoors, make sure to keep them somewhere up where they can’t reach.

Why do people consider Haworthia to be a poisonous succulent?

Looks can be deceiving.

It is their look that makes people think of Haworthia as poisonous.

Some varieties have a fleshy look, and some have an appearance of an Aloe Vera plant.

Some plants have a rich green color with white stripes with a thorn at the leaf tip.

They all look juicy, so people might think that the leaves carry poisonous sap.

The second reason behind thinking of Haworthia as poisonous is the fact that they are succulents.

If ingested, many plants in the succulent group are poisonous and they can result in diarrhea, depression, vomiting, etc.

Since Haworthia is a succulent too, many people unknowingly consider them poisonous.

But they have been listed in the non-toxic succulent group.

They are not toxic. But still, it is suggested not to ingest them.

When can Haworthias be toxic or poisonous to pets and humans?

Haworthias could be toxic when sprayed with pesticides, fungicides, or fertilizers.

When the plant suffers pest or fungus problems, we treat them with pesticides or fungicides.

During the spring and fall, most people apply fertilizers to Haworthias to boost their growth and help them grow faster.

You must ensure that no pets or children go near them for some weeks.

These sprays contain lots of chemicals that can be harmful to the health of living beings.

If your pets or children have munched a leaf, they will suffer various issues.

Consult a vet or doctor immediately for your pets and children respectively if they mistakenly ingest Haworthia leaves.

Though eating non-toxic plants won’t kill living beings, it is better to keep them out of the reach of pets and children.

Why do the animals eat plants?

Many pets, especially cats and dogs, eat grasses and plant leaves. It is because:

  • The plants carry vitamins and nutrients that could be missing in the pet’s diet. Haworthia and other succulents carry lots of nutrients and water in their leaves.
  • It works as a laxative that helps the pets in vomiting to cure indigestion if they have had it.
  • For a common reason, they are curious, anxious, or stressed.

How do I protect my pets from Haworthias and vice versa?

Haworthia watering

Indeed Haworthias are not toxic to any living being.

Still, protection is needed so that the plant sap doesn’t touch your skin. 

Along with that, you also need to make sure that pets don’t reach your garden.

Below I have shared some points which can stop the pets from reaching your Haworthias.

It will also protect your precious plant from destruction.

Create a fence.

The first and foremost thing you must do is create a physical barrier around your garden if you have pets and children at home.

Since they are innocent and curious, you must make sure they don’t reach your garden and create a mess out of it.

It will save your garden, your children, and your pets; together at the same time.

Grow toxic and non-toxic plants separately.

Don’t keep any toxic plants near your Haworthias.

Your pet won’t know which plants are toxic and which are not.

Once they are done meddling with Haworthia, they will try to go over another one beside them.

If you grow poisonous plants, like Kalanchoes or Jade, it will badly affect your pet.

So, grow toxic plants at a separate location with a proper barrier that only you can surpass.

Or, choose a zone where the pets or children don’t visit much.

Choose a suitable location to keep your Haworthias out of the pet’s or children’s reach.

You should not choose a safe location only for toxic plants.

Select a proper site for Haworthias.

Though they are not poisonous and no harm will happen if ingested, you should not take any chance. 

If your pet eats up Haworthias in large amounts, it might result in stomach or gastrointestinal upset.

That is why, either toxic or non-toxic, choose a location where the pets or your children won’t loiter much.

Choose a location where the pets can’t climb, or children can’t reach in an indoor setting.

You can also use hanging baskets, terrariums, or cages.

Use a deterrent

Deterring plants is easier for outdoors plants than indoors.

Outdoors, your garden will have a border.

You can spray some deterrent sprays, which can keep the pets away.

Citrus peels, lemon, cayenne pepper, chili pepper, and coffee grounds are some products that have such a strong odor that your pets would never loiter around your garden bed.

Some essential oils will also help, like eucalyptus, lavender, peppermint, or lemongrass.

Add ¾ parts of water in a spray and add 15 to 16 drops of the oil and spray it.

Repeat 2-3 times a month.

Aluminum foil

Tear some foils and spread them over the soil on the garden bed or containers.

You can even wrap a foil around a potted Haworthia.

Make sure that the soil in the container is slightly dry or the container is porous.

Aluminum foil can lock moisture for longer.

You can even surround your plants with pine cones.

Your pets won’t like to walk around the areas spread with such things.

Plant some strong-scented plants

Planting plants with strong scents near Haworthias can deter animals. 

Plants like Sage, Rosemary, Marigold, Lavender, etc., contain a strong smell hated by most animals.

How should I protect myself while dealing with Haworthias?

The only protection we need is for our skin.

When the sap touches our skin, it causes redness and irritation for some time.

Though it vanishes after some time, protect yourself if you don’t like it.

Wear long sleeve dress and gloves while dealing with Haworthias – spraying fertilizers, fungicides, propagating, transplanting, removing dead stuff, re-potting, etc.

Avoid loose-fitting clothes.

Wash your hand very well with soap or liquid hand wash after dealing with them.

Also, wash exposed parts of your skin that came in touch with the plant sap.

Do not burn any plant materials near your house.

The gas released might be harmful to you or the animals or other members in your house.

Always dump it in the garbage or bury it.

Final thoughts

Though Haworthias are not considered poisonous or toxic by ASPCA, you should not ingest or allow your children or pets to eat them. If consumed in large quantities, it might cause gastrointestinal upset.

Their sap may cause redness or irritation, which will heal after some time. If your skin comes in contact with its sap, wash it off immediately with soap.

Take protection while dealing with them. Follow the steps I mentioned earlier to stop the pets and children from reaching them, indoors or outdoors.
