Granular Worm Castings
Our premium earthworm castings provide a consistent, rich source of organic material to naturally feed all types of plants without affecting established microbial life.
Granular castings are dehydrated to 1/3 their original weight and volume. This makes each granule more concentrated and provides 3x more nutrition and organic material compared to fresh castings. Save energy and carbon without the need to transport excess volume and moisture compared to fresh castings.
Dried castings provide predictable and consistent results every time with every package. Fresh worm castings can vary wildly based on moisture content, what the worms are eating, and risk becoming anaerobic (bad) if improperly stored.
Granular castings are multipurpose can be used for indoor/outdoor gardens and plants of all types. Add as a top dressing or mix into your favourite soil mix. Worm castings contain essential plant nutrients including nitrogen, phosphorus, potassium, magnesium, calcium, manganese, iron, carbon, zinc, cobalt, borax, and copper.
Worms are an integral part of the soil food web, transforming our food waste and garden debris back into rich, healthy compost. See why garden professionals trust and use worm castings to grow beautiful flowers, delicious produce, and stunning landscapes as well as ensuring a healthy soil ecosystem.
