@mappingsupport@m.ai6yr.org when I had grapes west of Portland powdery mildew was the biggest problem. Give them as much sun as you can and keep on top of pruning to improve ventilation.

@mappingsupport@m.ai6yr.org I suspect choice of cultivar will make big difference in that direction. Hopefully someone more knowledgeable than I can chime in.

@intrepidhero@vmst.io just had a conversation with my wife where I lobbied to plant the grapes in the sunniest spot of the garden for just that reason
