Is it easy to be broken down? ' Q& N: N# G5 h
1 \" l1 @- c$ o7 o" }- }No, it breaks down slowly because of its high C:N. It makes a very attractive mulch as well, so if you have a lot of it I suggest spreading it on top of autumn leaves around trees or shrubs, or at the back of the bed where weeding is a chore.
