Is it easy to be broken down? : Q {: C4 F. v( |$ \* g
{6 \# p# p. w4 U9 \3 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./ r- y6 V5 p! I5 E9 K, K% T

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.
