Cucumber mystery

[Marb67]

I have been growing Marketmore with reasonable success this year (two in in a small raised bed and one with the runner beans in a large container). Out of three plants, one produced by far the most cucumbers in the raised be, with the one next to it not that many. The one with the beans (fed accordingly with borage) has produced absolutely zero fruits despite many flowers and the promise of little cucumbers that came to nothing. Looking at it now this is the best I have had but it doesn't seem to be growing.

So my question is, why when the plant is healthy, with many fruits forming does it not produce a single mature one ?

This is it's current state but I am losing hope of it growing any bigger.

Could just be because not all plants have the same vigour,I had 3 cucino cucumbers,I don't know what happened to one of them,it got to about 1 foot & stopped doing anything,the 2 plants next to it were fine. Maybe i overwatered it,the stem couldve rot underground for all I know. I wonder if the beans could have done something like releasing nitrogen & the cucumber could be having a lot of leaf growth instead of fruit growth but I think that happens when the bean plant dies down & they're supposed to be good companian plants. But it does remind me of a situation with my Buddleia that flowers late,its next to a ceanothus which is a nitrogen fixer & the Buddleia has mass leaf growth every year in the spring & late flowers compared to neighbours buddleias.

Marketmore is an outdoor variety that needs pollinating. If the 2 in the raised bed are close together they may be pollinating each other or the beans may have been attracting pollinators. The one in the pot may be in a position where it isn't getting pollinated. I had a similar problem with Vega which was growing in my growhouse with an open top. I had to resort to pollinating with a paintbrush.

They are pollinating because they start to form small cucumbers as in this photo.

Mine did the same. They look like they are producing a cucumber, but then the little fruits go yellow or brown and come to nothing.

Cucumbers are notoriously fickle. I grew Cucino (which doesn't need pollinating) in my friend's greenhouse. The earliest plant I grew produced a cucumber every other day or so during July and then suddenly all the little cucumbers went yellow and died. Then after a while it got going again and produced more cucumbers. I would have put it down to too hot/too dry/too wet/too cold... except that another plant next door to it (planted slightly later) was in full flow with the fruit at exactly the time when the first one was having a tantrum. I have no idea what was the matter.

I always start 4 cumbers knowing that some years one will die or not produce, I have no idea why but it seems a regular thing. This year however all 4 grew all 4 produced couldn't give em away fast enough.

Next year I shall still start 4 not knowing what will happen, just in case.

I started late this year (my first year) at cucumberin in july. Flowered well in early September. Had a slight movement in cucumbers growing then nothing. By reading the other posts my conclusion is that might have been over watered and did have spinach growing in the same container and that failed as well.

This year has been a learning curve with all my veg
