/ P( P# X+ Z# Q# o: ?/ d# MNo, 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.1 K3 w" z- R4 b# c; w5 m

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., w0 U% F2 i5 N: X8 k, s
