I use BlaCK HEN and can vouch for it, in fact, I go thru' quite a few bags of the stuff on my 100+ roses, it's not cheap but it's well worth it to me, I use it all thru' the garden on other flowers and veggies, etc. every other month or so, alternate with Alfalfa pellets, Milorganite, Black Kow, and other organics plus conpost, etc.... sally
