Good question.  Please post responses to list. 
Is after its literally curled with it too late?

Patricia and list,
I'm wondering then. I have a 2 year old rose
that is a cutting off my great grandmother's
grave and it has yet to have powdery mildew.
But cuttings from that same grave rose,  
(mother's and aunt's, 6 and 8 years old roses) 
and "mother bush" herself, is dreadful with 
powdery mildew right after blooming. 
Should I begin the "baking soda spraying" now
?
(just as she's beginning to bloom) 
Or wait till I see the stuff and then go for it ? 
How often should I spray ?

Carleen
