Hi , I have 2 ☓ 330 litre plastic compost bins, I wanted one made from pallets but by hubby scared of rats, got the bin's the end of summer, is it normal for nothing to have composted as it's been cold, I think the bins are ugly and are is a hidden shaded spot, should I put them somewhere warmer, also there isn't much of a way to turn and rotate the contents, not unless I tip it out and put it back again, I have composted all the correct stuff, just when I look I can still see un composted browns, composting sounded easy, but I've had no success. Any advice appreciated.
