If life gives you lemons... make lemonade.
If your Veronicas get mildew, make a bouquet!
I have had the same problem with these flowers for a number of years now. Just when they are ready to bloom, they come down with mildew -- powdery or downy, I don't know which.
Any idea on how to conquer it? Solutions anyone?
This year I tried keeping the area around the plant open so as to keep the air moving. Didn't work!
Also, I have other Veronicas, including this Royal Candles variety, and they are not susceptible to it.

Veronica spikes with a splash of pink Prairie Joy roses make a beautiful display.
