Last year I had a long row in the garden dedicated to cucumbers. I trained the vines to grow into each other and tried to keep them within their row (and not let them overtake the tomatoes).
This worked pretty well, but by the end of the summer I could barely reach some of the cucumbers or walk on that side of the garden because the row became so wide.
This year I decided to experiment with the cucumbers and try growing some of them on trellises. The only thing I was worried about was that the cucumbers would become too heavy for the vine and break off. But since I love to experiment (and I had a bunch of seedlings to spare) I figured what the heck, let's see what happens!
What a great success this has been for me. I am so happy with the way the vines have taken over the trellises and I've gotten a TON of cucumbers so far with more coming all the time.
There is much more room in my garden and the cucumbers haven't taken over any other plants.
Next year, I plan to grow all of my cucumbers on trellises and I am also going to try this with squash. I can't image all the room I will have!
Note: Not all cucumbers and squash are vine climbing types. You can also buy bush varieties, which will not climb a trellis. (Just in case you wanted to try this method.)
