Any suggestions? 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 3 years ago The trick with compost is to balance the moisture levels. Too wet and it lacks oxygen and stinks, too dry and it breaks down more slowly. Take the compost out and stack it to drain and to ‘air’ in the open. After a time it will be more manageable.
