Is it easy to be broken down? 8 u, H+ |- U( ?9 U5 e2 r# I" W

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.# Z& B( S: o% m
$ _+ w6 Z& K: f" e- aSpruce 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 [1 M: f; ?- g5 h
