I would do tomatoes, tomatillos, peppers, squash...hot weather plants and do the shade cloth. Maybe try some in containers. Also, if I don't start mine from seed myself I look for plants at my local Ace Hardware. They often have plants brought in from local growers so they're plants that are grown for your area. Plus I live near an agricultural university...they often have sales on plants for our area that do really well. Good luck. It's gotten really hot early here too. My cool weather plants are all starting to bolt...doesn't usually happen until June.
