Need help with cucumbers!

So, I think we are all beginning to focus on pollination as the issue Heat indirectly affects pollination in that pollinating insects are inactive above about 90F. And then you have the issue of housing the plants in a green house which may also be limiting access for pollinators.

No, not all. I have pollinators galore but the straight 8 cucs are all dropping fruit here. !00 deg F and 100% humidity they simply cannot support full fruit production....no matter the number of pollinators. It happens every year and has for decades here and will happen again next year and thereafter.

Going from dozens per week of perfectly formed fruit to just a few poorly formed stragglers...that's what heat and humidity do to cucs here.

Another upvote for Armenian cukes.

I'm going to give these a try...don't know why I haven't grown them before now...but partially because I kind of switch growing modes in August looking forward to the fall/winter garden.

According to AI, " Yes, Armenian cucumbers are notably more heat tolerant than typical cucumber varieties!"

agree with meadowlark mine here are burnt up i might get a couple more but thats it last two weeks of near 100 or more they just cant take it and u cant water too much as u will drown them

sometimes nothing u did wrong we just have bad seeds bad plants for no good reason and they dont turn out
crop rotation may help as well

Re Armenian cukes, I've been growing them for five or six years. As I said, inside of them, they look exactly like regular cukes, and they taste exactly like regular cukes. But be prepared, the fruit shape can be weird. Footballs, snakes, curlicues. They can get big. Sometimes called "yard long cukes". Kind of fun, really, but you can call them poorly formed fruit. I have them planted near an asphalt street, over which the air temp gets up beyond 125F in high sun. I plant out in March, and get loads of fruit for four months. But they kind of expire in August, maybe because the temps just get too fierce. You'd probably do better without a nearby street. Though I have other cucumis melo (canteloupes and honeydew) growing in the same bed, and they have no trouble. You can get plain light green or striped, which are attractive.
