Still No Cucumber Success!

15 Jul 2012
Rainy 17°C / 63°F

The 3 cucumber plants growing in the greenhouse are growing well and producing plenty of male and female flowers. As of yet the small cucumbers behind the female flowers have come to nothing and go yellow and fall off when no more than an inch long!

The plant is producing plenty of flowers and is kept well watered, but not too wet, but any idea why the fruits keep failing?

With ordinary cucumbers If the female blossom isn’t pollinated the tiny fruit will shrivel and fall off. I’m not familiar with this particular variety. Are you sure it’s parthenocarpic (able to produce fruit without pollination)? If not it needs bees. You could also try pollinating by hand.

I’ve had this happen with the first few fruits of the season and on other curcubits as well – agree with vaericks that it could be a pollination issue.

I had the same problem, which was partially improved by using a paintbrush to transfer pollen from male to female flowers. The females have an ovary that resembles the grown fruit, but will not grow without pollination. You might throw open the doors of the greenhouse and invite the bees in to pollinate, if there are any, and if not, it’s on you.

Thanks all, I’ve been opening up the greenhouse as halhurst suggested to see if that helps invite a few insects in to help with the problem. If not I’ll try doing it myself and see what happens.

Hi Russell, I had the same problem with my Cucumbers till a few days ago! The greenhouse door has been open for weeks as well as the window in the roof. There is also a sheet of glass missing on the side of the house where the Cucumbers are growing. I only got two fruits & I wrote a question on here like you. I got similar answers to what you got. Bees have entered the GH while I was inside & I’ve heard them buzzing around but I’ve not seen them enter the flowers. Like you I have no end of flowers on my plants but no fruit! I took a paintbrush down last week & dipped it into the male flowers & then into the female ones. On Monday I was in the GH & checked out the Cukes & I’ve noticed that several plants now have fruit! I don’t know if it was due to my intervention or the bees but I’ve got some more fruit at last! So give it a go with the paintbrush!
