As I mentioned in an earlier post, my neighbors and I have a compost tumbler that we are just starting to get the hang of using. One problem that we are experiencing is that the finished compost is not very fine, but rather clumped up in chunks like 'road apples'. We are not certain how to remedy this. One method we are experiencing with is to sun dry the compost out when it is finished 'cooking' in the tumbler, and then running it through a bagging chipper. Is there a more elegant solution to this problem?
