Worm humus, also known as vermicast, is the final product of decomposed material excreted by the king of the soil – the earthworm. This high quality organic compost is made from 100% pure, organic worm castings that have been stringently lab-tested to ensure they don’t contain any farmyard waste, landfill waste or compost. Packed with water-soluble nutrients and bacteria, our Worm·Humus™ is a very nutritious organic fertilizer and excellent all-round soil improver. Worm·Humus™ is perfect for refreshing All- Mix®, adding to substrate mixtures already in use, or preparing the garden subsoil. The ideal proportions to aim for are a blend of: 10 – 15% Worm·Humus™ to 85 – 90% All·Mix®.
