Gardner & Bloome Organics Worm Gro Earthworm Castings is a premium organic soil supplement created through the natural digestive process of earthworms, often called vermicompost. The castings are concentrated, plant-available nutrition that has been processed by living organisms, which is exactly what soil microbes recognize and use.
You can mix Worm Gro with your native soil, add it to your container mix, or use it to brew “worm tea” by steeping the castings in water for a nutrient-rich liquid feed. When applied at the drip line, it helps plants resist disease and pests while increasing beneficial microbial activity in your soil. Use it on a wide variety of plants, flowers, vegetables, and lawns.
