Benefits of Organic Spent Mushroom Compost

Mushroom compost has a high organic matter content, which makes it a useful material for soil improvement and mulching. Our organic mushroom compost comes as a by-product from our mushroom farming, it is excellent nutrient filled fertiliser. It contains high levels of calcium, magnesium, potassium and phosphate.

Our organic mushroom compost is easy to spread and increases the amount of organic material for your substrate and soil. This makes an ideal choice for gardening enthusiasts who are looking to grow vegetables, it is particularly good for brassicas due to its alkaline properties. This soil can also help with the structure of your soil and it is suitable for landscapers and gardeners. The properties of this soil mean it is best used with non-acidic plants such as camellias and rhododendrons.

Please note that there are two types of mushrooms composts, there is spent mushroom compost that has been previously used for mushroom growing. Which is like the type of compost that we provide. There is also un-used mushroom compost, this usually has less nutritional value so we do not provide this compost.
