Hi All,

My zukes still have heir initial leaves. How long
can I sky water them before I risk powder mildew?

doesn't powdery mildew is usually show up during
the hot and dry periods? for me that is later in
the season and some years it doesn't happen much at
all. seems to hit the bee balm and some false
sunflowers the worst, but they seem to survive
anyways so i've not done much to fight it.

i don't know what "sky water" means, but i'd
assume you mean watering from overhead? for that
i'd not water in the evening, but instead in the
morning so that the water can evaporate from the
leaves as quickly as possible.

I have listened to advice for years about when or how to water to
protect from wilt. I just wish someone could convince the clouds
overhead to comply.
