Mushroom compost

They deliver it to me on a pallet and I used a wheelbarrow to move the bags about 200ft to the end of my garden and left it there for a month or two - it's a good workout!
I find the the mushroom compost is often still a bit 'hot' so leaving it for a few weeks allows the composting process to complete.

 

I've just seen compost for sale in Lidl at £3.49 for 40l. That's cheap enough that even if it's poor, it's a starting point

 

I think I'll just do my usual and mix jacks magic with ji no3 and sharp sand.

It works ok but was hoping for a cheaper option.

I bought a bag or two of some unknown stuff a couple of years ago and nothing grew in it, god knows what it was contaminated with.
