Question: 1409-617
I have three pounds of diatomaceous earth that I have used on the soil under shade plants. Can I use it directly on plants to get rid of bugs? Karen, Townsend, MA

Mort's Answer:
Diatomaceous earth is mostly silica, which is chemically inert. It is not a poison or a neurotoxin. By placing the product under the leaves of plants, you are protecting the plant from invasion from creepy crawlies that can lay eggs on stems and leaves. This will be enough. Air borne insects are not a big concern. Fungi are usually air borne but diatomaceous earth cannot help. You have most of the root of the problems covered.
