% I7 W% \- @8 h$ G" HNo, 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.8 h" S4 |9 _) ~9 O. ?& v7 @

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.0 R/ d$ O$ a* G+ u, W9 w( x d
