For the first time this year I will be growing (have the seedlings all started) gourds, butternut squash, cucumbers, mini-melons in my garden. I have instructions to build a nice trellis for them, but find I have limited space. What I do have in full sun is a wood pile. Would that serve as a good trellis for these climbers? I figure they could just grow all over the logs and maybe cover them, they are a bit unsightly in the summer. What do you think of this idea?
