This is what 22kg of compost from one large (200 litre) YOLO Compost Tumbler shell looks like. I started this shell with dry grass, shredded autumn leaves and some fresh grass cuttings from my never-turned, neglected compost heap 13 weeks ago. The initial mix of contents was just about ready to empty a few weeks back when our gardener mistakenly emptied fresh grass cuttings into it – so we had to wait a couple more weeks. It is very satisfying to get such a load to dig into the garden.
