) |# f. m0 s* n: oNo, 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./ W0 R; n4 ~* p5 G6 L: J* {

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.* g% c' ]& H3 f$ {4 W
