Default Roses - soil conditioner question
wrote:
I grow roses as a hobby. This year has been especially bad for black
spot because of the abundance of rain. What is the best thing to use
against black spot?

You cannot really "cure" black spot. I've found that Orthenex, sprayed
every couple weeks works pretty well to keep my roses clear. It will
not remove existing black spot but will check the spread. Wear eye
protection when spraying with Orthenex.
