Is it easy to be broken down? 4 S ? V4 g3 J: U% e; E1 U& l* E. v$ \
/ f/ E. G) Y B! p8 oNo, 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/ n$ }8 D8 k
" ^* e5 X9 } l/ q8 u0 J' hSpruce 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.# e+ N* t! I# k0 S2 T9 J5 S0 i
