Mushroom Compost

Economical Blended Organic Mushroom Compost

Mushroom compost is an efficient, economical way to condition your soil, improving the quality and nutrient value of the soil it is added to, and promoting improved growth of decorative or food plants.

CPA Horticulture's mushroom compost is composed of composted agricultural straw and rotted manure, resulting in compost that is easy to crumble, spread and work with. Thanks to the compost's chemical and physical composition, it is perfect for improving the texture of heavy clay soils, or adding humus to nutrient deficient soils.

What's more, as our compost is fully steam sterilised before leaving the mushroom farm, it will not introduce any weeds or other pests to your site.

For general soil improvement a 50mm layer should be spread over the area to be treated, then forked or rotavated in. A 75mm layer could be considered with very poor soils.

Mushroom Compost: The Benefits

  • Friable, and easy to spread
  • Increases your soil's physical structure
  • Increases the level of organic material in your soil
  • Suitable for use by landscaping professionals and home gardeners
  • Very economical
  • Steam sterilised
  • Weed free

Outstanding product and an excellent delivery service. I ordered 40 bags of mushroom compost for my allotment and I couldn't be happier. After covering my plot with cardboard to suppress the weeds I created beds using the compost and pathways with wood-chips. An untidy and overgrown plot is now tidy and attracting loads of attention from other plot holders on the site. I am sure that CPA will be getting more orders from other plot holders as everyone has been so impressed by the product and service I received. I'm looking forward to a very productive year on the plot and will definitely be ordering again from CPA.

Very happy customer. Delivery of the 40 bags was prompt, the delivery driver was very helpful and got the pallet as close to the house as possible (I have already rung Palletways to commend him). The compost is lovely stuff, no unexpected bits and nice and warm! Little bit pongy, but only to be expected! Half of it on the garden as a mulch already. Will deffo use again.

Quality of compost seems very good. Unfortunately the pallet holding the 40 bags collapsed while it was being unloaded but the delivery driver should be commended as he was very helpful and moved all the bags which had fallen and stacked them safely. No bags were damaged so the packaging is very good.

After a bit of searching and reading reviews I opted for 40 x 75 litre bags from CPA at what seemed the best value around. Bit of a no brainer getting 40 bags instead of 20 given the small additional charge. It was delivered on a pallet from the back of a lorry via lift and hand forklifts. The driver was very personable and brilliant at manouvering the pallet to where I wanted it. As it came in sacks I just barrowed it into the back garden two sacks at a time. Beauty is that it's easier to deploy from sacks and you can just pile up any you don't need immediately. Much more convenient and cleaner than transferring from a bulk bag. It appears to be really good stuff with next to nothing in the way of rubbish - couple stones and pieces of plastic. Only slight downside was it really did pong - old clothes, gloves and a dust mask recommended, but that disappeared after the first rain. When I need more I will return for this and have recommended it to family and friends.

Mushroom Compost.. Not quite as rotted down as I expected, still some very coarse bits of straw. However using as a top mulch so it's acceptable. And all the plants that I have dressed this around all seem to be looking healthier that 4 week previous to adding. Delivery was quick and the driver very helpful. Will buy this again - have recommended to fellow allotmenteers.

This mushroom compost is excellent stuff. Clean, weed free and in bags that are easy to handle, it is great applied as a thick mulch. It is largely odour free and keeps beds looking tidy all summer as well as holding moisture and suppressing weeds. I use it everywhere except around plants and shrubs needing acid conditions as they don't like lime.
