Wiggle Worm Earthworm Castings are a clean, odor-free way to upgrade almost any soil without risking fertilizer burn. This 30 lb bag is 100% castings with a mild 1-0-0 analysis, which provide steady nitrogen plus soil-building benefits that help roots explore and hold moisture more evenly. The castings include some fast-available nitrogen and a larger slow-release portion, which is why they work well for both seedlings and established plants. We apply Wiggle Worm when we want better growth and better soil texture at the same time, especially in containers and raised beds.
Use the castings to condition planting holes, top-dress beds, or blend into potting mixes to improve aeration and water handling. It’s also a solid base for casting tea for hanging baskets or hard-to-reach planters. Because it’s gentle, it fits into a routine without forcing you to micromanage rates or worry about scorching roots.
