Organic Gardening with Diatomaceous Earth
by Debbie Hart
Diatomaceous earth is a naturally occurring soft sedimentary rock, made up of the fossilized remains of diatoms (a type of hard shelled algae) and often crumbled into fine white powder. While most commonly used as a filtration aide or an abrasive in various products, I’ve adopted it as my go-to for pest free gardening!
While I love to pick fresh, organic produce from my garden to create fabulous summer meals, there have been years where my produce didn’t survive the ongoing attacks from bugs and mold. Having been gardening for decades, I’m thrilled to share a key to my gardening success that has kept my veggies healthy and free from both bugs and toxic chemicals.
How it Works
As bugs and pests walk through, diatomaceous earth works into the joints of their exoskeleton, making microscopic cuts – proving fatal to all pesky insects from aphids and ants to fleas and even roaches. Non-arthropods like humans, pets, and your helpful garden earthworms aren’t affected by DE.
Additionally, I love to sprinkle the product around the perimeter of my house, which stops bugs in their tracks before they enter and become a real nuisance.
Incorporating the effective and protective power of diatoms into my gardening has been a true win-win – flourishing fresh veggies from an earth friendly and organic solution.
