The real solution is to start new cucumber plants around the end of July.
I've known this for 25 years. I have never done it.

:-(


You've known it but never done it? You sound like me LOL. I read somewhere
that you should exactly that - plant several sucessive crops so that you
have young vigorous plants when the old ones die off. My cucumbers are
pretty much spent, I wish I would have planted some fresh ones a month ago.
My mutant acorn squash was planted in the beginning of July, and it is
healthy, vigorous, no sign of mildew, and just now starting to produce. I
expect to get a lot of goodies from them until the frost hits.
