Is horse manure compost suitable for planting?
I want to plant new shrubs
As long as it is well aged and composted in a "hot" compost pile, it is fine. Otherwise it may have weed seeds in it, depending on what the animal ate. Do not use any manure that isn't fully composted! Check out this webpage on horse manure. Notice the links at the top, including how to tell if the manure is ready for garden use. http://whatcom.wsu.edu/ag/compost/horsecompost.htm
