This is my secret sauce! This is by far the best compost you can buy for your garden/farm/pots! I’ve had plants respond so well!

It is a by product from the mushroom production so you can get it cheap and delivered local for cost of transport https://www.cpa-horticulture.co.uk/mushroomcompost?search=Mushroom
