; q- K- F( q6 E9 J8 F4 ^' L- iNo, 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.( @% N# X) i- Q! e, t
6 B( t/ Q: P9 p+ D; D% Y) 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.
