P; h+ o* F8 T5 vNo, 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.7 m; z: ^+ D! ~; h& y
! y' V, z& K. ~; C+ T3 \/ iSpruce 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.3 T3 ^! _0 a9 W4 Z x! h0 {
