White powdery mildew
I have one rose. Not special rose, just a small thorny thing, but an old
buddy. Every Spring it suffers from white powdery mildew and I try various
things on it which may or may not works well. This Spring I was gone a lot
and it suffered to the point it did not provide the first set of flowers. I
finally got time with it and trimmed back severely and treated with some off
the shelf stuff which seemed to work.
What do I use early on before serious infestation occurs to help this rose?
Thank you
Jim
