Richgro All Purpose Mushroom Compost

Stones sold as mushroom compost – I have used this mushroom compost for a while, and initially found it to be OK.But over time, I have been finding an increasing number of stones in the mix.Recently, I found around one fifth of a bucket of small stones, plus a rock which weighed 1.5kg! So, needless to say I shall not be purchasing this product again.As stones do not have anything to do with mushroom compost they must be using them to keep up the supply to Bunnings.Pretty disgraceful way to run a business.
