Mushroom Compost - Bulk Bags

In stock
Product Details

A recycled product, Mushroom Compost is a fantastic way to condition your soil.

A high specification soil conditioner which is made up of chicken and horse manure mixed with wheat straw, this versatile compost breaks down creating good microbial action resulting in the production of humus. This attracts the right type of insects to the soil whilst preventing pests and discouraging diseases.

Mushroom Compost will increase the amount of moisture that the soil holds, in turn aiding the retention of nutrients meaning that plants will require less watering.

Since this compost can only be used once in the cultivation of mushrooms, it is a sustainable way to help your plants flourish.

Fungal properties in the compost also provide protection against drought and intense heat. With the ability to break up clay-like soil, mushroom compost is an exceptional soil conditioner and is economic to use on a large scale.

Our Mushroom Compost is ideal for use in flower beds, vegetable gardens, and for raised beds. It also works well as a light mulch.

Suitable for:
