Worm Castings


Our worm castings are of the highest quality and uniform size. Worm castings increase the amount of available Nitrates, potassium, magnesium, calcium, and phosphorous in the soil while also increasing the beneficial microbes plants need to utilize those minerals.

Adding worm castings to your garden will increase the water holding capacity of the soil and make the moisture readily available to your plants. Worm castings are a 100% organic fertilizer and are safe to use on all forms of plants. Use them dry or as a fertilizer Tea.
