Diatomaceous Earth: The Natural, Versatile Pest Control Solution
Gardeners are turning to a natural, versatile solution for pest control: diatomaceous earth. This fossilised water plant, composed of silica and trace minerals, is a safe and effective way to combat a range of insects.
Diatomaceous earth works by physically damaging pests' protective outer layers, causing them to dehydrate and die. It's harmless to beneficial soil microorganisms and humans, but safety precautions like wearing a dust mask are recommended during application.
There are two main application methods. For dusting, cover both sides of foliage and reapply after rain. For spraying, mix 1 cup of diatomaceous earth with 1/2 gallon of water, keeping the mixture agitated. This method controls pests like aphids, thrips, ants, and mites.
Diatomaceous earth can also be used as a paint on trees and shrubs. It's crucial to use 'Food Grade' diatomaceous earth for garden use, as other types may contain higher levels of free silica. Its use in gardening dates back to its natural properties as a fossilised remains of diatoms, traditionally used for pest control and soil improvement.
Diatomaceous earth, with its unique composition and natural properties, offers a safe and effective alternative to chemical pesticides. By understanding its application methods and safety precautions, gardeners can harness the power of this fossilised water plant to protect their gardens from a wide range of pests.
