How hot has it been there? My cousin used to raise a 1000 acres of cucumbers a year. He said when it’s too hot that they just make vines. If it cools off, they’ lll make lots of fruit. He seems to be right from what I’ve seen. I think the blooms just get too dry too fast. Hand pollinating could help, but not having bees may not be the whole problem. There are lots of pollinators besides honey bees too.
If it’s not hot there, then I’m all wrong.
