With a quarter sheet of plywood and a few 8' 1x2's I was able to assemble this trellis for my one and only sugar pumpkin. When it reaches the top I'll train it around and back down the trellis and by then I should have another side vine growing up somplace. The first female flower on this plant is ready to open. Perhaps tomorrow. There is a male lower down on the vine that also looks like it will open soon. Maybe too soon. That's the problem with only growing one plant.
