This “Golden” zucchini looks wilted during the day but in the evening it stiffens up again. Any idea what is going on? I don’t see any borer holes anywhere…
Probably borers or root rot.
what temps you got right now? my zucchini wilts when it gets close to 85 but perks up in the evenings.
Mine will do that when it’s hot.
A lot of broad- and thin-leafed vegetables do that. Only a problem if leaf edges brown and crisp, or if there is no day-to-day recovery.
I have found that my zucchini and squash do so much better when they get some shade in the afternoon.
The temps are mid 80F the last three days, but just went through 3 weeks of 90F+. This is my first year growing this variety so it is possibly just not sufficient for my growing conditions.
I don’t see any borer holes, and I have watered them sparsely to avoid powdery mildew, but we did get a torrential rain Saturday, which I guess could’ve helped induce root rot. I’m definitely not growing this variety again since it is the only squash with issues.
They do that here it’s to hot. Put some shade cloth over them in the heat of the day. We don’t worry about it we let them wilt. Watch out for squash bugs they love those! Keep sevin dust on hand. When they wilt from those they don’t come back to life at night.
It could be bacterial wilt that’s transmitted by cucumber beetles.
Yeah when my cucumbers / melons start looking like @jeremybyington photo. Its because they got bacterial wilt. You can test for it like this:
A common diagnostic test for bacterial wilt involves cutting a wilted runner close to the crown of the plant, rejoining the cut surfaces for a moment, and then slowly drawing apart the cut ends. The presence of bacterial slime (masses of bacteria streaming from xylem tissues) extending from one cut surface to the other is a positive indication of bacterial wilt.
I guess I could cut it down to near the crown since I noticed a new stem sprouting a few inches from it. I’ll do that in a couple days. So busy with a deadline at work and a ton of blackberries to harvest in what little free time I have.
