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$ R2 E2 b1 w
, \+ q* z4 k9 I! P! H9 W; RSpruce 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.
