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.
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.

Super friendly team. I ordered a load of topsoil delivered when I was not at home. The driver ensured it was unloaded in the correct place and took their time to move bins and leave enough space for the garage door to open and for the car to park. Highly recommend Corker to anyone looking for a professional service.

Plenty of choice of stones, rocks, aggregate and slate. Nice friendly helpful people. Drove nearly 2 hours to get there, but pleased that I did.
Andrew • 11 months ago
Fantastic service - delivery next day at no charge and the delivery person went that extra mile to get the load close to the work site - closer than I dared hoped for -saving me huge amounts of ‘wheelbarrowing’.

Simon • 11 months ago
The team at Corker were brilliant in helping us understand exactly what we needed and took the time to run through the product selection and provide recommendations where we asked for them.
Luke • 11 months ago
We had been disappointed with the quality of what stone masons were offering for stones on the top of graves. We liked what Corkers had and they got four bags ready in no time, loaded them into the car and refused a tip. Within 45 minutes the two graves were sorted. They look great.

Corkers is a business I have used for many years. They are a very well run family business who always put the customer first, nothing is a problem to them and they have never let me down!
Richard McCombie • 1 year ago
I have been using Corker for years now and I feel that I don’t need to go elsewhere! It’s a one stop shop for all of us landscapers but what’s just as good is the fact we can send our clients there for inspiration for their gardens.
Jake Fairweather • 1 year ago
I purchased 3 bulk bags of topsoil and 2 of compost. I rang them first to discuss delivery issues that there could have been with this kind of delivery. the person on the phone was really helpful, the delivery driver arrived on the appointed day, at the appointed time. he was helpful, very jolly and rather brilliant.

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.

Thank you to Corkers for a great delivery service! We are preparing a greenhouse base alongside various other projects and the Corkers delivery man was kind enough to rearrange all our materials on site when delivering our top soil. Thank you. This company is highly recommended!
