I have cucumbers growing in my greenhouse here in Arizona. A lot of my new baby cucs are turning yellow before they have a chance to mature. Can anyone tell me what to do to prevent this? I'm not even sure why they are turning yellow and dying. HELP!!!!

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/garden-how-to/beneficial/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/fruits/melons/hand-pollinating-melons.htm
