I grow using raised squareI grow using raised square foot gardening methods as well. I use 1 melon per foot. I do clip side vines and try to keep to 2 vines max per plant. I made some adjustments to my beds. My melon beds have an 8 foot tall trellis made with three 2x4s and chicken wire. A cattle panel would work well too. The net fell last year due to weight of the melons. The 2 foot bed will be fine. I wrap my vine up, over, down, then back up again tying the vine gently every few inches for support. A cattle panel would probably allow you to wind the vine in and out, but I used what I had. I get better results with the stronger trellis. I wouldn't go more than 4 feet without a 2x4. We helped our friends put together their square foot garden beds and they bent the cattle panels over from one bed to another in an arch and planted shade loving veggies under it. Works well. Slanting it would help support fruit too. Hope this gives you some ideas.
