How to Put Diatomaceous Earth on Houseplants

Diatomaceous earth is a natural and effective way to control pests on your houseplants. It is made from the fossilized remains of diatoms, a type of algae, and is widely used as an organic pesticide. Not only is it safe for plants, but it also poses no harm to humans or pets. If you’re wondering how to apply diatomaceous earth on your houseplants, follow these steps to keep your greenery healthy and pest-free.

Step 1: Choose the right type of diatomaceous earth
There are two types of diatomaceous earth: food grade and pool grade. It’s important to use food grade diatomaceous earth for your houseplants as it is safe and non-toxic. Pool grade diatomaceous earth, on the other hand, is chemically treated and can be harmful to plants.

Step 2: Prepare the diatomaceous earth mixture
Mix one cup of diatomaceous earth with one gallon of water in a spray bottle. Shake well to ensure the mixture is thoroughly combined.

Step 3: Identify the pests
Identify the pests that are infesting your houseplants. Diatomaceous earth is effective against a wide range of insects, including aphids, mites, thrips, and ants.

Step 4: Apply the diatomaceous earth mixture
Spray the diatomaceous earth mixture directly onto the leaves and stems of the infested plants. Be sure to cover all areas, especially the undersides of the leaves where pests tend to hide. Repeat this process every few days until the infestation is under control.

Step 5: Reapply after watering
Diatomaceous earth loses its effectiveness when it gets wet, so it’s important to reapply after watering your houseplants. This will ensure that the pests are continuously exposed to the diatomaceous earth, ultimately eliminating them.
