Reply To: Horse manure

[Beth]

My neighbor has offered me some of her horse manure (which I know isn’t contaminated with herbicide). She warned that there may be a few rocks though. I usually sift my finished compost with a sieve and I am now doing slightly raised beds (trying to put logs on them for sides). I can’t really sieve this year-old horse manure and am wondering if a few rocks in raised beds is worth the manure. I would love to have it as there is never enough finished compost! How big an issue are some rocks in raised beds?
