Benefits:

Improves Soil Structure: Worm castings are cylindrically shaped pellets that resist compaction and keep the soil loose. This allows root growth space and promotes excellent drainage.

Will Not Burn: You never have to worry about over fertilizing

Beneficial Bacteria and Microbes: Worm castings contain high concentrations of beneficial bacteria and microbes from the earthworm digestive tract. These microscopic organisms create healthy, living soil for optimum growth.

High Availability of Nutrients and Minerals: The earthworm digestive tract uniformly mixes the nutrients and trace minerals found in the soil so plants can easily absorb and use these substances as needed. In addition to containing Nitrogen, castings also contain small amounts of Phosphorus. Potassium, Iron, Calcium, Magnesium, Sulfur, Boron, Copper, Zinc and Manganese.

Contain Plant Growth Hormones: Worm castings naturally contain Auxins and Cytokinins, growth hormones which enhance plant roots.
