Can You Put Diatomaceous Earth on Potted Plants?

Potted plants are a popular way to add some greenery to your home, and keeping them healthy is essential. One question that plant owners often ask is whether they can use diatomaceous earth on their potted plants. The answer is yes, but with some precautions.

What is diatomaceous earth?

Diatomaceous earth is a naturally occurring sedimentary rock made up of the fossilized remains of diatoms, a type of algae. The powder that is used for gardening and pest control is made from the silica shells of these diatoms. It is highly absorbent and has many uses, including as a soil amendment and insect repellent.

How can you use diatomaceous earth on potted plants?

One way to use diatomaceous earth on potted plants is as a soil amendment. Adding a small amount of diatomaceous earth to potting soil can help improve drainage and prevent soil compaction. This can be especially beneficial for plants that are prone to root rot.

Another way to use diatomaceous earth on potted plants is as a natural insect repellent. The powder works by dehydrating insects that come into contact with it. To use it as an insect repellent, simply sprinkle a thin layer of diatomaceous earth on the surface of the soil. Be sure to reapply after watering or rain as it can be washed away.

What precautions should you take when using diatomaceous earth on potted plants?

While diatomaceous earth is generally considered safe for humans and pets, it can be harmful if inhaled. When handling it, be sure to wear a dust mask to avoid inhaling the powder. Also, be careful not to get it in your eyes or on your skin as it can cause irritation.

Additionally, it is important to use food-grade diatomaceous earth when using it on potted plants that are grown for consumption. This type of diatomaceous earth has been treated to remove impurities and is safe to use.

Conclusion

Diatomaceous earth can be a useful tool for keeping your potted plants healthy and free of pests. It can improve soil quality and act as a natural insect repellent. However, it is important to take precautions when using it and to use food-grade diatomaceous earth when using it on plants that are grown for consumption.
