Our earthworm castings (vermicast) are an excellent all natural plant food and soil mender. We raise our worms on a large scale with great care so that they produce a consistent nutrient packed casting every time. These castings, or manure from the worms are full of easy to absorb nutrients for your plants because the worms breakdown the materials that they eat so that it is easier for your plants to absorb them. The nutrients that the castings contain are slow released and work at building up the soil they are added to.
