We sell to the customer a soil amendment that is like giving your plants steroids. The all organic food that is ingested by the worms is changed, physically and chemically by the process of digestion and becomes homogenized. It is safe to use directly from the bag on virtually all plants. No need to worry about measuring and/or over-use. This product is safe on bedding plants, potted plants, lawns and seeds. Each casting pellet is in the shape of a tiny cylinder. This shape resists compaction and helps to keep the soil loose. This helps the oxygen to permeate down to the root zone where it is needed. Drainage is improved due to the lack of soil compaction. Trace elements, Microbial Activity, and nitrogen fixing bacteria are all what makes this product out perform other fertilizers.
