Help! Cucumbers

[Heathofhares]

Please can anyone suggest what I can do with my cucumbers. They are the outdoor spiky ones and the plants are growing ok, but I have only had one decent sized fruit. All the others seem to be going yellow and not growing beyond about 3cm?

They are growing vertically supported by strings if this makes a difference?

I’ve not been watering recently because it’s been so wet and I have fed them a few times with sea weed fertiliser.

Sounds like they are not being pollinated

Thanks for your reply - Is it possible to hand pollinate them. (We have loads of bees on all the flowers nearby so not sure why this has happened?)

In that case it may not be lack of pollination. But I don’t know what it is then

In theory you should be able to hand pollinate, but the flowers look very fiddly. I’d try a paintbrush
