It’s really hot and muggy here in the Summer as well. Our choices are, 1). start them VERY early, like right now and set them in the garden VERY early and protect with frost cloth and hope we don’t have a late *very* cold and wet spring. 2). start them in early June and plant them out for a fall garden sometime in the middle of July.
The only tomatoes I got last year were from plan 2. Plan 1 failed because we had a very cold and wet spring followed by an almost immediate transition to 95+ and no rain for 6w. You can imagine how my tomatoes just LOVED that!
We must live close! Same weather pattern here.
We do plan 1 and 2 as well. Works great unless we have a hurricane. :)
