Is it easy to be broken down? / R- n- i! Z) I5 P
0 d' G- W+ V" w* K) hNo, 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.8 a% t2 j0 U2 F1 r3 q5 x0 C2 R) j

Spruce needles are another matter - because they are thicker, and have a pointy end, they can poke you as you spread your compost - wear gloves and you will be fine.
