Oddly Queasy about the concept of Bone Meal
Last year I put a layer of bone meal on my roses and bulbs, because it was the only thing I saw that was clearly identified as being appropriate for both. Both really seemed to benefit dramatically.
The idea of it grosses me out, though. Maybe it's issues with mortality, vegetarianism, giving more support to the meat industry (or whatever they make it out of!) than I care to -- but what would be the closest alternative?
I'm thinking manure or compost for the nitrogen and phosphorous and some kind of calcium or magnesium salt (is it calcium sulfate) for the other nutrients. Would this achieve more or less the same effect? I have some new roses I've tried not to fertilize too heavily in their first year, but how much manure, etc. would be good for their second?
