How to Use Diatomaceous Earth for a Pest-Free Garden
If you’re new to gardening and searching for a natural way to protect your plants while improving soil health, diatomaceous earth (DE) could be your perfect ally. This versatile, eco-friendly powder offers pest control, soil conditioning, and composting benefits all in one! Here’s a comprehensive guide to using DE effectively and safely in your garden.
What is Diatomaceous Earth?
Diatomaceous earth is a natural substance made from the fossilized remains of microscopic algae called diatoms. These algae are rich in silica, and their fossilized deposits are mined and processed into a fine powder with unique abrasive and absorbent properties.
Important Note: Always use food-grade DE in your garden. Pool-grade DE, while similar in appearance, undergoes chemical processing and is unsafe for plants, animals, and people.
