I have since left the escapees to their own devices.
Fortunately they have started forming in the bed and not so much outside. There is also a bitter melon plant in the corner, the only one to survive. It's flowers are much larger and I don't think it has made a melon yet.
The smaller melons still look mostly green and there's plenty of flowers for more to start forming. I scattered some pepper seeds in today to hopefully give a litle more sun cover and keep some more of the moisture in. They like lots of water.
The larger ones are starting to get some stripes but still no netting yet. Give them a few weeks and they should be netted and ready for picking. They probably won't get as big as the ones in the store but they're sweeter.
