Is it too late...?

I've grown cucumbers a couple of times in the past and this year I decided to grow some normal ones (ie male and female) and also some all female varieties......of course I've managed to mix up the labels and don't know which is which! Not so bothered about this apart from one thing - previously I've put them in the GH border once all my little seedlings are planted out and there is space for them........not quite at that stage yet but two of my cukes have cucumbers on them.....so on the one hand I am chuffed to bits...but on the other hand, I KNOW they arent in big enough pots for the rest of the growing season and i dont know if they can be repotted/planted into the border when they have fruits on them?

Does anyone have any advice for me please?

And also what type of feed should i be giving them as there seems to be a fair bit of conflicting advise....

Many thanks folks
