Question
We have a cucumber plant that is huge and taking over our tomatoes; this is our first garden and we're not sure what to do with it.  It's next to a fence and we've tried to wind it around that, we also bought a trellis for the other side, but can we prune it now? It has lots of flowers but no cucumbers and our other, much smaller plants have already produced fruit.

Answer
I don't advise pruning this plant, if you want it to produce very many cucumbers. It is going to get much bigger. It will need a very big trellis, or wire fence to contain it. The best thing is to "train" it. By that I mean, make it go where you want it to go. If it is going into your tomatoes, make the vine go in a different direction. Up if you can. But, if not, then to an area where it isn't bothering the other plants. Cucumbers need their own garden, as do most other large vines. So next year when you grow them, I would suggest you are prepared for them to be the monsters that they are, and give them plenty of space.
