What is diatomaceous earth and how does it work in gardening?
Diatomaceous earth (DE) is a natural, fine powder made from the fossilized remains of tiny, aquatic organisms called diatoms. These organisms have a unique silica-based structure, which gives DE its abrasive characteristics. In gardening, diatomaceous earth serves multiple functions, mainly as a natural pest control agent and soil amendment. When pests come into contact with it, the sharp particles pierce their exoskeletons, leading to dehydration and eventual death.
Additionally, diatomaceous earth can improve soil quality by enhancing aeration and drainage. Its porous nature helps retain moisture while allowing excess water to escape, making it an excellent addition to sandy or clay-heavy soils. This dual role of pest control and soil improvement makes diatomaceous earth a versatile tool for gardeners looking to promote healthy plant growth.
Is diatomaceous earth safe for pets and humans?
Yes, food-grade diatomaceous earth is considered safe for both pets and humans when used properly. It’s important to distinguish between food-grade DE and industrial-grade DE, which contains higher levels of crystalline silica and can be harmful if inhaled or ingested. Food-grade diatomaceous earth can be used in gardens, as well as around the home, to control pests without posing a significant risk to people or animals.
However, while DE is safe when handled correctly, it’s advisable to wear a mask and protective eyewear when applying it to avoid inhaling the fine dust. Furthermore, it is essential to keep it away from food storage areas and ensure that pets do not ingest large amounts of it. When used thoughtfully, diatomaceous earth is a non-toxic solution for managing pests in your garden.
How can I apply diatomaceous earth in my garden?
