I would like to try square foot gardening this year and to save space I wanted to grow a few things up on a trellis. I have cucumbers and melons that I thought I might try to grow up, but I'm not sure how to start them up it. Will they just tendril around the supports or do I need to do something to get them to grow that way? I'm growing pickling cukes and vine peaches and cantaloupes. Can I grow the cinderella pumpkins on a trellis too, or are they too big?
