Is it easy to be broken down? - b7 ~; l8 r, ?/ I! v; F
# S9 r' o o. ~9 KNo, 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.2 h: O9 t' K' D3 K9 U: j
# Q& M# J. O. X. E7 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., ^' `6 |- n3 q3 ?; Z0 P. ?
