mushroom substrate is the composted organic material remaining after a crop of mushrooms is harvested.

• Mushrooms are grown in a mixture of natural products, including horse-bedded straw, hay, poultry manure, ground corn cobs, cottonseed hulls, gypsum and other substances
• This product is fantastic for breaking up heavy clay soils as the high lime content helps break down the clay particles whilst the manure breaks down more slowly making it a perfect mulch for flower borders and vegetable beds and particularly where roses and shrubs are to be planted. Please note, using mushroom compost will increase the PH of your soil immediately after use, neutralising over a short period of time.
