5 T7 x% N; N( A9 Q7 p6 p% ?1 BNo, 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." D* I! e8 t1 Y: K. L
9 K/ S+ g# ~1 T Z& |% xSpruce 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.
