Last spring, I got more of the Vancouver compost mix and steer manure than I actually used. Last fall, my husband and I ground up all the leaves that fell and I have several bags of leaf mulch that I haven't yet used. I can easily identify the leaf mulch, as it is in orange or green garbage bags. However, I can't distinguish between the manure and the compost (I know, I thought a sniff test would be enough, but it isn't :) )! My question - Should I mix all three as a kind of "super mulch"? Or should I just mix the compost and the manure? I usually put lots of steer manure around my roses at this time of the year and wondered if the triple mix (or double mix) would be ok for them. Would there be anything that I should avoid putting the triple or double mix around? Any advice???
