This is my first full year with my garden in this location, and I bought greencure because I had heard so many horror stories of trying to grow "old" and "English" roses so close to the ocean (I've about 35).

I've had very good success with it warding off and/or eliminating PM. I've had a very little PM here and there, but nothing compared to my neighbors (who all seem to be growing Iceburg, and all seem to have PM everywhere in their gardens). I love that I don't feel that I am spreading "poisons' around the yard. I think that as long as you use it on a (at least fairly) regular basis, you might expect good results. I'm hooked and going to continue using it next year. I'd say.. give it a try and see how it works for you.
