We have combined and blended our two best-selling organic composts to create a super compost blend, providing customers with an extremely versatile compost and mulching product. This 50:50 Compost is produced using only natural composted organic materials which are contaminate free. Our Organic Soil Conditioner is fully certified to BSI PAS100:2018 (the British Standard for composted materials). and is a friable, dark, rich, fine compost packed full of natural nutrients and minerals which will slowly release into the soil over time, greatly improving the natural properties and performance of the soil.

Our Spent Mushroom Compost is derived from organic local mushroom farms and is a great natural soil improver, excellent for breaking up heavy clay soils, adding organic matter to inert sandy soils and for mulching vegetable beds and flower borders.

Packed full of nutrients and richer in organic matter than either horse manure or mushroom compost, the one limiting factor of our super fine soil conditioner is its lack of body. Our Organic Mushroom Compost has considerably more body, being produced from a mix of peat and well-rotted straw blended with either aged chicken or horse manure but, being a spent product, it lacks the high nutrient levels and minerals typically found in soil conditioner.

We have resolved these issues by creating a 50:50 blend of each product which, in combination, have the necessary body and nutrients required to create a super composting mulch. The combination of these products naturally improves chemical and physical properties and the long-term performance of soils whilst significantly increasing organic matter and improving water retention, naturally boosting nutrient and nitrogen levels and enhancing and restoring the natural structure and stability of the soil.

For general soil improvement, spread a 50mm layer of our blended Soil Conditioner and Mushroom Compost over the area to be treated and fork or rotavate it into the soil. For extremely poor or nutrient starved soils, consideration should be given to increasing the application to 75mm or even 100mm. This super compost mix can assist in restoring the natural balance of soils, encouraging a healthy growing environment in which plants can thrive.
