Worm cast is best used as a first class natural fertilizer, use it sparingly and selectively around the garden - a little goes a very long way!
Studies have shown that worms convert organic waste into the best natural fertilizer known – worm cast. It contains from 5 to 11 times the quantity of available N – P – K (nitrogen, phosphorus and potassium) than the soil the worms consume to produce the cast. The worms also drastically improve the soil structure. Each worm can convert up to their own weight of waste into worm cast each day.
