How to Use Composting Worms

Composting worms thrive in moist bedding and feed on food scraps such as vegetable waste, coffee grounds, and paper products. Because they are surface dwellers, they are best kept in worm bins rather than traditional compost piles.

For beginners, starting with proper bedding and moderate feeding helps establish a healthy system.
