Is it easy to be broken down? ; u0 b) J+ L9 m! c# e6 h
# o6 ~, j% W; y9 V0 X/ ANo, 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. Z# c; g. I; i" @ X7 z
4 K# h. ~4 U+ [5 R) GSpruce 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.# ~7 m4 g' d' _. P) H% E
