Fertilis Earthworm Castings are a premium soil amendment made from the natural digestion process of earthworms, producing one of the richest forms of organic compost available. Also known as vermicasts or worm humus, this dark, crumbly material is packed with beneficial microbes, nutrients, and humic acids that support robust plant development.

Using Fertilis Earthworm Castings provides immediate benefits to both garden beds and potted plants. They improve soil texture, enhancing water retention and drainage while offering a slow-release nutrient source that feeds plants without the risk of burning. Their gentle nutrient profile makes them perfect for seedlings and sensitive plants, while still offering the power to boost flowering and fruiting in established crops.

Beyond just plant nutrition, Fertilis Earthworm Castings contribute to a healthier garden ecosystem. They stimulate microbial activity in the soil, which improves nutrient cycling and suppresses soil-borne diseases. By restoring microbial balance and improving root health, they promote sustained plant vitality. Whether added directly to planting holes, used as a top dressing, or mixed into potting blends, they transform tired soil into a thriving, biologically active growing medium.
