Is it easy to be broken down?

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.5 j; G; [' w. J' `8 A0 n. I7 k) J* y3 K
