Q.Cucumbers shriveling
I am growing cucumbers in containers, as I have for years, but this year they are inside a screened enclosure around my pool. Plenty of sun, no exposure to pool chemicals. Vines are growing like crazy and dozens of blossoms, but cucumbers grow to about 2 cm long (very thin) and then turn yellow and shrivel to a brown thread. The watering is even with no episodes of over or under watering. What is happening? I had one cucumber actually mature, but no others! Thanks.
It is a pollination problem. When the flowers are not pollinated, the plant "aborts" the fruit because it will not make seeds. This article will help: https://www.gardeningknowhow.com/ornamental/trees/teak/insect-pollination-process.htm
You will need to hand pollinate. Cucumbers are identical to melons on how they pollinate, so this article will also apply to cucumbers: https://www.gardeningknowhow.com/edible/vegetables/cucumber/hand-pollinating-melons.htm
