这个问题我请教了有很多compost经验的专家Mark:

Is pine needle a good material in yard compost? ( }2 [' s J$ P" y

Is it easy to be broken down?

. H+ g% ]$ O$ A. a n0 F2 jNo, 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.

" t% Z& x5 s, |2 C9 E& CSpruce 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., d$ n4 F" i4 X- |
