Loading... Please wait...Mealworm Frass is a natural soil amendment made up of fine insect waste, shed exoskeleton material and small particles from the colony's bedding/feed. It is useful for gardeners who want to add organic material back into potting mixes, beds or established plantings.
Frass is concentrated compared with ordinary compost, so a little goes a long way. Mix it into soil or potting media rather than piling a heavy layer directly against stems. For established plants, it can also be worked lightly into the soil around the root zone and watered in.
This listing is sold by the pound. Because it comes from a working mealworm colony, texture and particle size can vary somewhat from batch to batch.
