Compost can also be produced using worms. This is known as worm farming. It is also called ‘vermiculture’ or vermicomposting.
Usually tiger worms are used for worm farming in NZ, though red worms can also be used. Worm farming uses the same principles as composting, but it does not generate heat, making it cold composting. Value is added to the materials when they are eaten and excreted by the worms. This produces what is called vermicast and worm tea which have high levels of nitrogen, phosphorous and potassium (NPK) compared to ordinary soil. This makes them valuable for your plants’ leaf growth, root and stem strength and flower and fruit set.
