If you\'re working with heavy soils, you know how hard it can be to create that dream garden. Mushroom compost improves the condition of your top soil and is a highly effective soil conditioner for improving structure in heavy clay soils and adding humus to sandy and chalky soils. Don\'t waste peat or more expensive products! Mushroom compost is ideal for increasing the fertility of your garden soil. It is weed, pesticide and disease free. The mushroom is a choosy feeder and after cultivation a high level of nutrient remains in the compost which is available to green plants. Mushroom compost is made from wheat straw, horse and poultry manure which are mixed and composted together. Once used, is it sterilised by the mushroom grower, and then bagged.
