Last Spring was the first time my parents used worm castings exclusively to fertilize their garden. My mom and dad claimed their best tomato crop they can remember. We used a handful of castings with each tomato seedling, and the results were terrific. Even in one of the driest and hottest years on record, the taste, yield, and size of the tomatoes were outstanding.
Worm castings or earthworm manure is the best all natural fertilizer you can get. Beyond Potassium and Nitrogen, worm castings are alive with beneficial microbes. Beneficial bacteria, nematodes, and other tiny beneficials that will add life to plants and soil. You can maximize your castings harvest by brewing compost tea. You will need an aquarium pump, water, castings, and some unsulfured molasses to amplify the effects. Worm castings are the only manure that can be directly absorbed by plants roots. They are perfectly pH balanced and won’t burn up plants like other high in Nitrogen manures.
