Is it easy to be broken down?

. ~, L! D8 W1 ?: {" ^* JNo, 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., S P7 s4 Q# R5 |$ t% w' A, E( D
