A sustainable byproduct of vermiculture, earthworm castings are one of the most powerful natural amendments you can add to your soil. Packed with slow-release micronutrients and trace minerals, they boost microbial life, reduce transplant shock, aerate and condition your soil, and add chitinase (a natural compound that helps suppress disease and control root knot nematodes.)
 
Safe for indoor and outdoor use on everything you grow, and works in harmony with your existing fertilizers and soil amendments.
