First spring after we moved in I planted a few new roses and rescued/transplanted 2 that were here. I also got some for free on their last legs in exchange for some azaleas We had way too many azaleas. Saved 5 of 8 bushes which surprised me. I mostly ignored them last summer but am working a lot with them again this year. Seems to be having an effect - a blosssom opened today on one bush and lots of buds on the others.
Anway, here is the recipe I use from a good local rose place. My tweaks are I alternate Orthenex Rose Pride (fungicide and insecticide) and the Halt every other week. My totally untested theory is the fungii can't build a resistance to one or the other if I rotate them. Plus the Orthenex is available at homecenters. I do not use the Orthene. During Japanese beetle season I will switch out the Orthenex for the Halt and add in liquid Seven.
1 gallon water
5 teaspoons Captan 50%
2 ½ teaspoons Halt - brand I use is Ferilome
1 ½ teaspoons Acephate/Orthene
½ teaspoon Spreader Sticker
