No, I would leave them alone unless you like eating teeny tiny cucumbers. They are working very hard albeit perfection takes time. The plant must divide it's energy among all the fruits. They taste best around 5-8 inches. Any bigger, they start to decline in taste & texture. Keep them well watered and a good balanced fertilizer. They are very hungry & thirsty plants at this stage.

Thanks B, i’ll do just as you say.

What type are they Hank?

The friend who recommended them to me said they were telegraph I’m pretty sure. Hers last year extended across her greenhouse roof. Mine are about 7 ft tall just now.

They're doing you beggar all good as massive vines if there's no decent cucumbers? Sounds like a variety to be avoided in future? & if you leave them & then you get ten or twenty useable cukes in a week what good is that? You couldn't eat them all & they don't store for long.
Take half or more of the little ones off & pickle them as cornichons or gherkins or something & stop them growing taller imo

Sounds like a plan D, will try it on one of my plants.thanks.

Have just lopked thoroughly at my cuc plants and have found one 3 about 9 inches long, but they’re only 1 1/4 inches diameter. They were deep in the foliage. Will check one out with my salad this evening.

That's a good result then! I had a cuke a couple of years back that grew down behind it's container, it was the size of a marrow! The skin was really thick & the seeds were big but the flesh had a nice melon kind of texture
