Can you put worm castings on top of soil?
For established houseplants, apply ½ to 1” of worm castings over the soil line and mix the castings into the top 1” of soil with your fingers.
Repeat this process every 2 to 3 months from spring through fall for healthier plants and lush leafy growth!
Skip the lawn fertilizer and use worm cast compost instead!
