Is it easy to be broken down? ; ~( s5 u# i2 B7 q9 F& l0 P

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./ M1 o1 y: d1 l3 N. @) h
