Cucumber not fruiting

[Marb67]

I have a Cucumber (Marketmore) growing in a long tom with compost with a hole cut out the bottom so the root system can spread into the large old aluminium tub that is planted in (also 2 Courgettes) So far there have been no cucumbers, a few flowers and just a weeny, pathetic cucumber about 10 cm that doesn't get any bigger. I am feeding with comfrey liquid and seaweed.

Seems like there’s too many plants of the same type planted together in a container. Did you mean 10mm not 10cm? 10cm would be alright My cucumbers are behaving strange for the first time ever,keep giving male flowers,they’re all female variety ‘Diva’. I think they were stressed with the hot beginning they had,the temp in June must’ve set them back from fruiting happily.

I’m still waiting for my first flower

Marketmore is an old fashioned variety which needs pollination to set fruit (most modern varieties will set without pollination), so my first guess would be that they simply haven't pollinated.

I've grown La Diva for a few years, and despite claims to being all-female I have never found that to be the case. They always seem to produce both male and female flowers, and early season often produce only male, especially if they are stressed.

I’ve grown diva for years too,I’ve never seen so many male flowers,it does show stress when they give male flowers I’ve had about one male flower occasionally with this variety shortly after planting but I planted these ages ago,usually they are growing a lot of female/cucumbers by now,it’s really different this year. I’ve got three more younger plants to plant out soon so I’ll see what happens with them,hope they don’t get stressed bout something

My La Diva are also producing male flowers and all varieties are behaving oddly. This is Mini Munch, in my greenhouse (the La Diva are at my friend's but are doing the same thing)



The cucumber at the top of the picture is about ready but there are 3 or 4 small ones below it that are clearly not going to develop and are starting to go yellow. The plant is in a self watering pot and has not been allowed to dry out and it is an all female variety that does not need pollinating, so the only conclusion is that it didn't like the weather when those flowers were developing. It has done a lot better than the other Mini Munch I grew, which was planted at the allotment and keeled over and died for no apparent reason. The leaves at the bottom of the plant are going yellow but the top of the plant is almost at the greenhouse roof and looks very happy.

Have to say, I have given up trying to grow cucumbers.
Year after year I have tried all types and varieties.
I have had them in the greenhouse, out in the garden, in containers and every which way with little or no success.
I buy them in the supermarket and use the space for other things.

I'm growing 3 Beth alpha cucumbers I picked the first on 23rd June then nothing since, very strange.

[Marb67]

Still only one small fruit growing and the foliage is yellowing. Fed with all advised here

Looks similar to the colour of one of my pumpkin plants. It was a spare so in a smallish pot for a while after I planted the others out. I planted out in a bed and it has gradually gone back to a healthier green colour although smaller than the other plants. I haven’t particularly fed it with anything I think it just needed more nutrients and space.

[Marb67]

Still yellowing, one pathetic fruit from 3 plants (the other 2 in another container) and yet my sister in law has them growing in a large bean tin (much smaller than my space) and producing copious cucumbers. It's just unbelievable

Is it the same variety? We have two one in opposite corners of our greenhouse, one is doing much better fruiting wise than the other. Think the difference in their case is one has been getting more sunshine and not as much water, but maybe not *shrugs*

[Marb67]

She gave me one of the cucumbers in a pot to plant on. The other 2 are marketmore which have loads of flowers but only one tiny fruit forming. Feeding with comfrey etc and they do get sunshine.

[Marb67]

Well, still no cucumbers on other 2 healthy plants with plenty of flowers that don’t fruit or fall off. Feeding as advised. Its absolutely ridiculous and doesn’t make sense. The other yellowing, pathetic plant has given up.

I have said it before and will say it again, the quality of shop bought seeds has rapidly gone downhill. I shall try and source them from a reputable mail order company next year.

Absolutely gutted 😡

If you've got healthy plants, Marb, what makes you think the seeds are to blame? Could it not be a lack of pollination or plant stress?
