Compost - to cover or not to cover?
I have been making compost for quite a few years - well trying to! I get maybe two barrow loads after two years of adding, turning, blah blah blah. I have had some good heat, obviously most notably when the grass cuttings or plant shredding in autumn goes on top. I have two self constructed wooden cubes with air gaps. Farmers, I think, put black plastic over their heaps in the fields. So should I do the same and if so would it be worth putting something thicker for greater insulation. I know it might be awkward when turning but if it improves my yield I can live with it. BTW I think I do the normal things like green and brown waste and turning, even tried mixing in industrial wood shreddings. It all works but very slowly. I live in Dorset but I do not think external temperature that important. Any thoughts?
