Thompson and Morgan sell a variety of Courgette which we have found
to
be resistent to Mildew. Not sure of the name off hand, but it is
advertised as such.
Onions adore sun. And do not omplain too much about Spring onions,
in
40 odd years of growing veg I have never even managed to get the
seeds
to germinate, never mind grow to any size. And before you all jump
in
and tell me how to do it, I have tried every single method ever
suggested without success.

Another cause of powdery mildew is lack of air flow. If your plants
are
protected from the wind, mold will be a problem. Too many plants
crowding each other will also prevent air flow. If plants are indoors
a
small fan will also help plants.

Indoor zukes?

There were problems this year with the north "Bay" grape harvest. A
cool, damp summer gave way to a cool fall. Fearing mold, and mildew,
vineyardists pruned back the vines foliage to allow better penetration

of sun and air. That's when we got a week of heat that sunburned many
of
the grapes, creating points of infection for the molds and mildews.
Then
as quick as you could say "Bob's your uncle", we started getting light

rains. The winery where I worked lost a third of its crop.

Agriculture isn't for the faint at heart.

Or the optimist

I was thinking perhaps greenhouses. They sometimes do not get good air
circulation. Also this is the first post were someone grew Courgettes in
pots that I know of. I also wonder what size of pots are used? They
would need at least a five gallon container.

Another thought, you stated ZUKES, I was thinking squash not cucumbers.
There are varieties of cucumbers called pickling cucumbers that will die
if the cucumbers get large and go to seed. So if I am wrong and the OP
was growing pickling cucumbers then that is the reason for the plants
early demise. Is there a variety of squash that acts like pickling
cucumbers?
