Why should I use worm castings in my garden?

Worm castings are full of organic matter, micronutrients, and microorganisms that work harmoniously to permit a more bioavailable, pH-resilient soil. The microorganisms naturally present in worm castings work slowly over time to continue to release vital plant nutrients.

Worm castings contain up to 10 times the nutrient levels of lawn soil, but possess low levels of essential nutrients like iron, which means it won't cause nutrient or pH burn, unlike commercial or artificial fertilizers. Also unlike traditional fertilizers, the makeup and structure of worm castings works to store and retain nutrients, preventing water leaching vital nutrients from your soil.

Increased water retention and improved aeration also improves soil structure, resulting in happier, healthier roots and plants.
