Hi David,
I'm very interested in your results - and mine. I'm new to my hot area and have read about tomatoes not setting fruit in the heat, so I'm trying a couple of different methods to keep getting tomatoes through the summer. I do not have the large garden you have. I have raised beds and pots, some in the ground, and some pots I've got in shallow containers of water with part shade. This is the first time I've grown tomatoes from seed to harvest (woohoo!) and really paid attention - it's much different than elsewhere.
Temps are in the nineties (97 yesterday) during the day, low 70s at night. All the plants in the ground or raised beds have fruit, the pots are varied.
I've planted two on your list - Early Girl and Isis. Early Girl started giving me ripe tomatoes about two weeks ago, Isis started just this week.
I've also planted
Black Cherry, doing very well so far in a raised bed, pots, and also on a trellis in the ground, ripe.
Rutgers, almost ripe
Roma, ripe and picked - plants don't look happy. These are in the ground.
Mortgage Lifter - the one that was almost ripe had worms in it;
Brandywine - not yet turning
Wild Cherry - seems happiest of all. Lots of little tomatoes.
Thanks for this thread!
