Enriching Soil

Designed to enrich your native soil.

Worm castings, also known as vermicompost or vermicastings, are created when organic matter passes through the digestive system of earthworms. The earthworm’s special digestive process transforms organic material into a fantastic soil supplement that plants simply love. Combine G&B ORGANICS WORM-GRO with your native soil or use it as an effective “worm tea” to fertilize a variety of plants, flowers, vegetables and even lawns. By mixing WORM-GO into your soil at the drip line, you’ll be helping your plants resist disease and pests while increasing beneficial microbe activity that creates a great soil environment in-ground or in-containers.

PROVEN ORGANIC
