Melons!! Me too!
Hot hot hot- they love it HOT and sunny.
They need a lot of nutrients, like cabbage, they are hungry plants.
So, I grew sweet potatoes for the first time last year and followed directions for these more northern locations, and pre heated the soil and used black plastic all season under the plants. I had more starts, so put those in warm soil, but not preheated, and no black plastic under them. What a difference with the black plastic! So, I’ll use the same idea for the melons this year.
FWIW, I start melons from seed in hills directly in the the garden. If you start seeds, just be aware melons can be temperamental with transplanting, so only start a few weeks before transplant and/or use a larger container for the seeds you start.
We have had some good success with melons. We’ve tried many varieties. Some grow fine then die quickly from wilt. So, try several varieties.
Good luck
