Is it easy to be broken down?

; n+ t+ @* l1 ~! l5 t6 Y- A7 aNo, 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: }+ G; o7 e( [6 H1 [
5 S' t! p/ j; C& h4 ^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.3 G6 W* R9 K+ ~" N
