Premium Worm Castings - 5 Gallons (Extra Large Box)

$57.97

Worm castings are nature’s most complete soil amendment, created as worms break down organic matter into a rich, living compost. Biology in a box! Often called “black gold,” castings are packed with beneficial microbes, enzymes, and nutrients that plants can easily absorb. Unlike synthetic fertilizers that sterilize soils, worm castings are all-natural, gentle, and safe—there’s no risk of burning plants or harming the soil. They work by improving soil structure, increasing water retention, and feeding the living ecosystem beneath the surface.

Perfect for flowers, fruits, vegetables, and even houseplants, worm castings support stronger roots, healthier growth, and more vibrant blooms and harvests. They help plants build natural resistance to stress, pests, and disease while improving long-term soil health. Free from chemicals and fillers, worm castings nourish both plants and the land, restoring soil the way nature intended—slowly, sustainably, and full of life. The 5 gallon box is perfect for covering 32 square feet of soil at a ¼ inch thick or placing ¼ cup of the soil amendment into 320 plants.
