Mushroom Compost
Mushroom Compost provides the perfect medium for all varieties of growing.
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, seeding and turfing lawns and for raised beds.


It also works well as a light mulch.

What is soil improver?

Soil improver is made up of decomposed organic matter, water and air. 
The organic matter in our soil improver comes from all natural garden waste, making it 100% organic and peat-free.

Why should I add soil improver to my soil?

Adding soil improver to your soil will improve it's structure and condition as well as adding much needed nutrients to the soil. 
Soil improver will also help your soil retain moisture, making water more readily available for plant roots. 
It is also widely used to loosen up heavy clay soils by restoring the structure of the soil and reducing compaction. 
Soil improver also helps to balance the PH level of your soil.

When should I use soil improver?

You can use soil improver at any time of year but it is best to use it when the weather is not too wet to avoid compaction.  With heavier clay soils it may be best to wait until Spring. 
You can also wait till your flower beds or vegetable patches are empty and add it then.

 How do I apply soil improver?

Dig over the area in question, just the top layer of topsoil. 
Spread a layer or soil improver over the area in question about 2cm deep. 
Avoid digging too close to plants or their roots as to not to damage them. 
Using a fork, work the soil improver into the topsoil, be sure not to dig too deep and disturb the subsoil.
