Is it easy to be broken down? & n( h4 ` J; I. {4 e$ c% R
$ A8 c0 P4 E) j" d; _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.

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.2 R4 e5 P- w ^3 B: M
