What compost mix for poataoes in sacks?
To get the other half involved in more hands-on gardening I've bought him a set of 3 potato sacks and seed potatoes. It was a little late and they've not chitted too well but I think they need to be planted now to have any chance.
What compost should we use? I was thinking along the lines of peat-free shrub & tree, garden and mushroom. Anything in that to sacre the horses or anything missing?
