% H4 ~% s! |, m8 c: S! z$ G, |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.: [$ i* p8 l* i4 _" y1 J1 W: s, k
! G3 L5 R' Q# Y0 C+ G: ZSpruce 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. ~; M' @4 ?5 X8 g& Q
