A spent mushroom compost derived from organic local mushroom farms, our Mushroom Compost is a great natural soil improver which is excellent for breaking up heavy clay soils, adding organic matter to inert sandy soils and for mulching vegetable beds and flower borders and it is one of our most popular composting mulches.
Mushroom Compost is sourced solely from organic mushroom farms and fully steam treated before sale to 50 degrees, which is maintained for a minimum of 4 hours. Produced from a mix of peat and well-rotted straw blended with either aged chicken or horse manure. The resultant product is high in organic humus, which naturally improves the chemical and physical properties and long-term performance of all soils, making it a good, economical solution, for both professional users and discerning gardeners alike.
For general soil improvement, we recommend spreading a 50mm layer of Mushroom Compost over the area to be treated, then fork or rotavate in. For very poor nutrient deficient soils, you could consider increasing the application to 75mm or even 100mm.
Mushroom Compost helps restore the natural balance of soils, providing a healthy rich growing environment.
Please Note: Our Mushroom Compost is a very rich compost and it should be mixed with soil prior to planting. It is not a suitable medium for the potting or seeding of young plants and we would not recommend it’s use for this purpose or for utilisation as a direct growing solution as results may vary significantly. In these instances, we would recommend use of either our Multi-Purpose or John Innes Composts.
Our Mushroom Compost is a bi-product of the mushroom growing industry and whilst we test the material regularly we does not produce the mushroom compost directly and, as such, cannot guarantee the ingredient, chemical or nutrient composition found in the compost.
Being a natural product, the colour and texture of the compost will vary depending on how fresh the compost is. The fresher the mushroom compost, the lighter in colour it will be with more straw visible in the early stages which will darken and decompose naturally over time. On very rare occasions this product can contain trace elements of plastic which is unavoidable as it can happen as a direct consequence of the mushroom farming process.
