Mushroom compost is a gardeners favourite! This highly organic matter is a by-product from the mushroom growing sector, and can be used effectively to help break up heavy soils and increase aeration in the soil.

It's really useful in vegetable patches and is great to add in if you're growing cabbage, broccoli, cauliflower, kohlrabi, Brussels sprouts and kale.

It's also useful as a soil conditioner for borders and to help roses, trees and shrubs. With a chalky base, it's alkaline in nature and makes an excellent mulch to boost the nutrients in your garden soil.

Can also be known as spent mushroom substrate or SMS.
