Worm Castings are a complete organic fertilizer that is produced naturally by earthworms.
Castings are Mother Nature’s purest form of a sustained release plant food. This product can be used on all plants without fear of burning even the most delicate plants including cactus.
Worm casts consist of granules, surrounded by a mucus, which hardens upon exposure to air. When granular castings are mixed into garden or houseplant soils there is a slow “time release” of nutrients. However, the hardened particles of mucus do not readily break down. Instead, they serve to break up soils, providing aeration and improving drainage. Worm casts therefore provide an organic soil conditioner as well as a natural fertilizer.
Worm Castings are packed with minerals that are essential for plant growth, such as concentrated nitrates, phosphorus, magnesium, potassium and calcium. It also contains manganese, copper, zinc, cobalt, borax, iron, carbon and nitrogen. However, the best of all is that these minerals are immediately available to the plant, without the risk of ever burning the plant. Remember that animal manure and chemical fertilizers have to be broken down in the soil before the plant can absorb them.
Recent advances in microbiology and soil chemistry have shown that it is the product of the earthworm activity called vermicompost that raises soil fertility and increases plant performance.
The many benefits of worm castings in raising long term soil fertility come from its ability to improve the physical, chemical, and biological properties of the soil. Healthy soil like a healthy person is better able to thrive under demanding environmental conditions
