Mr Watmore’s Mushroom Compost is a premium quality garden compost, the answer to clay and heavy-based soil's as it's a blend of Manure, wheat Straw and gypsum which improves your native soil and breaks down clay-based soil's! Simply spread around planting holes when planting or use as a mulch and work into existing soil.

Did you know that mushroom compost is not composted or broken-down mushrooms, but in fact the growing medium in which mushrooms are cultivated?


  • Improves soil structure so that water, air, and energy can move freely through the soil. Good soil texture should be crumbly to the touch, not clumpy or sandy.
  • Increases nutrient content in the soil. Many of us know about soil nutrients like nitrogen, phosphorus, and potassium, but organic matter also builds up copper, iron, zinc, and manganese.
  • Uses less water. When soil structure and texture is healthy, it retains water more efficiently, leading to less water usage (and lower water bills !)
  • Keeps plants healthy. When the soil is fertile, plants are happier. And happy plants have fewer problems with disease and pests. The healthier your plants are, the less need you have to use chemicals to treat pest and disease issues

An all round
compost that slowly release natural goodness whilst absorbing water then storing and releasing it as the plant requires.

Ideal for improving native soils can be either worked into the existing soil or used as a Mulch over borders, lawns and allotments.

Our no.1 Soil Improver Mushroom  Compost improves soil structure, helping sandy soils to retain moisture and heavy soils to drain better. This fantastic compost naturally boosts the number of beneficial bacteria and fungi in the soil. All of this makes it easier for plants to take up the nutrients in the soil, allowing them to grow bigger and healthier.
