Worm castings, or vermicast, are an organic form of natural fertilizer and the end-product of the breakdown of organic matter by earthworms. By adding organic worm castings to the soil you are providing manure that aerates and improves the structure of the soil while also making beneficial nutrients that stimulate plant growth.
Packed with beneficial bacteria and minerals, worm castings are rich in water-soluble plant nutrients such as nitrates, phosphorus, magnesium, potassium, and calcium, while also providing amounts of copper, manganese, zinc, cobalt, borax, iron, carbon and nitrogen. They can also be beneficial by naturally repelling pests like aphids and spider mites as well as improving the soil’s ability to retain water, creating aeration in your soils, does not burn the roots, does not contain any heavy metals, and increases the growth of a healthy plant.
