Protozoa populations are perfectly balanced and stunning! Normally you’d use 50 lbs as a top dress per 100 sq ft of worm castings, but with this material, you can get away with 20-25 lbs because the biology is so rich.

What are Worm Castings?

Earthworm castings, frequently referred to as "the superfood of plants", are the biologically-rich waste by-product that earthworms produce after eating.  Through a specialized digestive process, earthworms convert organic matter into an even more nutrient-rich compost called worm castings.
