My Cucumber Plant In Greenhouse Has Dozens Of Flowers But Cucumbers Are Not Developing, Any Reason Why?

Question

I have grown cucumbers for a few years but usually have two plants, this year only one due to garden centres being closed earlier. My daughter in law gave me one of hers, so wondered if it needs another plant to help germinate?

Answer 1

No, they will be self fertile, and pollinate itself.

You may just have all male flowers, or all female flowers. This will resolve itself, at some point, but this can be normal.

Here is an article that will offer more insight into hand pollinating, which may be necessary:
