Is it easy to be broken down? / P& s3 }" [- u- D: ]
8 c9 u6 a' z! p r9 W! tNo, 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.

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.% F9 Z( w; n7 ?/ j% |+ s1 g
