You rang? LOL!!!
Ok. Here's the skinny on growing tomatoes in MY yard (Houston)....
It (usually) gets brutally HOT here by the 1st of July. The heat lasts well into mid-September. My goal is to pull my last tomato by the end of June, and rip the vines. They're ratty and diseased by then, and not worth trying to carry over in all the heat. Additionally, once the humidity sets in and the temps avg. greater than 82°, the pollen clumps and doesn't fly in the breeze (contrary to popular belief, bees are NOT needed to pollinate tomatoes -- but, they sure help!)
To this end (harvesting the maters by the end of June), I have to set transplants out here by the 2nd weekend in FEBRUARY. Yes. That's not a misprint. FEBRUARY. Basically, the middle of winter, here in Houston. I have all sorts of frost contingencies in place, and PLAN to protect the seedlings once they're transplanted out. In order, I use: PVC hoops (almost year-round), perforated plastic sheeting, solid plastic sheeting, old sheets, lightweight mover's blankets, old Christmas tree lights (the ones that heat up), hot water filled milk jugs, and, if push comes to shove, a small space heater under the covered hoops. To date, I've only had to go as far as the first four contingencies, combined. No plants were lost to frost.
This sounds like a lot, however, in the grand garden scheme, we have only a handful of nights that dip below freezing. And very rarely for more than a day or so in a row. So, it's only a night here and there to protect the plants past the solid plastic covers.
I start seeds indoors on the weekend closest to the Winter Solstice (December 20th). I pot up once after the first set of true leaves, grow them for 5-6 weeks, harden off 1 week, transplant them out on the 8th weekend from sowing the seed.
If you protect them, and have the proper sunlight to grow them, you should have full production by mid-April to mid-May.
Historically, I grow long-season (85-120 DTMS) indeterminate heirloom tomatoes. Beefsteaks. When I had the proper sun patterns I was successful. However, a large tree is sucking up my sunlight, and I am not able to grow tomatoes like I want to in my yard. Have to decide on tomatoes vs. the tree....
Sioux (
NOT Super Sioux) is the most heat resistant tomato I have ever grown. It is a fine, tennis-ball size slicer that grows in clusters of 6-7 fruits, like perfect huge grapes. I literally had to stop watering them during our 2011 drought, because I couldn't take the heat. They, on the other hand, were just fine, as long as I kept going out to water them!
You might also try Mortgage Lifter and Kellogg's Breakfast. Just get them out as early as you're willing to protect them.
Hope this helps!
