 You'll need airflow, so try to apply a layer of woody garden waste at the base of your compost pile, such as pruned peaches and dead flowers. The texture you are going for is crumbly and smooth. You really want your compost to be damp, but not too watery. Lastly, make sure your compost is receiving enough oxygen by turning it over regularly with a shovel or pitchfork. Or you could use a tumbler to mix up your compost. Once a week should do it.
