I have been following the thread on spraying roses with miracid is this the concentrate that you feed azaleas and camellias? Would someone explain how they do this and the results does it really help deter blackspot ? I live in Central Florida the capital of blackspot so am always interested in hearing about good results in deterring blackspot. I have around 150 roses and just learned to graft so plan to have many more. Joyce Dillon jdillon@gate.net http://www.gate.net/~jdillon/ ICQ 5609261
