This is a real time shot of it.

Wow that's a lot to fit into that small space. The notch entry faces west, right? I'd put the tomatoes along the back wall trellis so they don't shade everything else, the squash on the north side trellis, all the peppers in the south end, and find somewhere else out of the garden for the melons. It all depends on how many plants of each you want.

You could space 4 (maybe 5) tomato plants on that back wall, maybe 4 pepper plants in the south block, and 2 squash plants in the north end block.

Hope that helps.

definitely helps. perhaps I should have been more clear, I do not plan to plant all of the same things in here again this year. I definitely want to do tomatoes and bell peppers again. the rest I will likely plant somewhere else, especially the melons. open to suggestions on anything else, was thinking maybe some carrots in front of some of the others where I don't have trellises.
