Plant squash, bean and cucumber varieties that vine (not bush varieties). Plant these on a trellis (in the case of cukes and squashes) or, in the case of pole beans, up a bean teepee. A teepee can be made of any long, slender poles (I used furring strips I found in my garage, and tied them together with zip strips). For pole beans, the teepee should be at least 5' tall. You can use fencing as a trellis as well, whether it's chain link, chicken wire, welder wire, or whatever you have. Plants might need a little guidance to know where to grow, just be sure to treat them gently so you don't break the stems.
