1. For House Plants & Seed Starts: Mix 10-15% castings with potting soil. Castings may also be worked into the top layer of potted plants, taking care not to damage roots.

    2. For Garden Starts: Line seed furrows with a thin layer of worm castings, or place a few tablespoons beneath each transplant.

    3. For Garden Soil Enhancement: Gently work the castings into the topsoil or sprinkle castings over soil and cover with mulch, then water.
