Worm Castings


GroundScore™ Organic Worm Castings can be used as an ingredient in potting soil (as plant nutrients) for plants in and around the house. It can also be used as a planting additive for trees, vegetables, shrubs and flowers. Because Worm Castings will never "burn" plants, you can use as much as you like!

  • Our worm castings are concentrated and organically produced
  • We produce our castings indoors in a climate-controlled environment
  • Castings are isolated from pests or extreme weather conditions that would cause leeching

We also offer handcrafted soil blends and a select variety of organic GMO-free seeds for your home gardening needs.

We can't find products matching the selection.
