Product Description

Spent mushroom compost is an affordable high-quality source of vital plant nutrients, mainly used to neutralise acidic soils. It is low in soluble nitrogen (which means a much lower risk of plant burn) and high in minerals like phosphate and magnesium for strong and healthy plant growth. You can use it year round as a moisture-retaining mulch or dig it in to improve deficient soils.

Spent mushroom compost is especially brilliant at breaking up heavy clay soil, making it easier to work, which we know is the holy grail of gardening for many of our customers in the South-East!

Our compost bags have added fibre and are pre-screened to avoid weed and mushroom spore contamination.


Perfect Your Soil’s pH

Treat your broccoli and Brussels sprouts to a deep conditioning treatment. Soil conditioning, that is! Alkaline in nature, mushroom compost is just the ticket for neutralising your soil, creating the ideal conditions for growing Brassica and root vegetables. It’s also beneficial for flower beds and rose bushes but do avoid using it with your ericaceous (acid-loving) plants.

Highly recommend

I can't believe I haven't used Corker sooner! They were the only company to deliver what I needed, when I needed it. Their website was simple to use and even has tutorial videos on how to get the most out of the products.
