2 LB. Frass – Dry Mealworm Castings


Insect frass is a natural fertilizer produced by sustainable insect farming on our family farm. It’s made from from the larvae manure and exoskeletons of mealworms. It is naturally dry and the texture is like extremely fine sand. It is surprisingly dense, and heavy. Frass has many of the same benefits of guanos and earthworm castings.

Frass can be used to mix with tiny seeds, like you would with sand, to sprinkle the seeds consistently in rows with the added benefit of “green manure” you can safely directly sow with the seeds.
