This was all a bunch of awesome information, thanks!
Dry farming early girl tomatoes (as described in the link) sounds very appealing. Especially in my grandmother's yard. This is kind of what happened last year, actually, haha. I watered in the beginning for a few weeks then asked my grandmother's husband to water the plot for us for like a week...
I came back and he just DIDN'T water it once in a week it felt like. Okay. Maybe once. But every thing got fried, and it didn't work out as dry farming???
(The fact that he didn't water the tomatoes was kind of dumbfounding, uhh, they had a soaker hose and all he had to do was turn a knob in a highly accessible place.
Everything tanked or almost died. And I realized I wasn't going to make it there every 3 days to water so I kind of gave up entirely.
And they still had a few tomatoes. But omg, it would of been awesome to set them up with "dry farming" in the first place.
Soo, in real life this year, I had actually posed this question
While looking at my early girl tomato plant!
And I noticed that it looked ... the opposite of plump! Almost like sunken in! (Not quite, but more toward sunken than plump, hah)
Unfortunately, mine is in a pot so the idea of "dry farming" where the root goes six feet away (or a few feet/etc) to get moisture is not possible/not something to shoot for at all. And it is actually my first year growing in pots and the first year being hyper aware that wet leaves/wetness causes disease...
But I don't wanna parch the tomatoes in a quest for health
It actually rained and the tomatoes look different/definitely more plump. So there's your answer I think, they did look sunken in due to not having enough water, imo.
(I'm also aware I DON'T want to over-water them to try to inflate them, haha. They aren't like water balloons. Or if you do they won't taste good. Besides other problems.)
But I am not trying to dry farm in a pot. So. Now I know I need to water more now that the temperature is going to be 85/90 instead of 70/80! (Which is obvious I guess but this is the first year with tomatoes in a (7 gallon) container so I definitely have to learn what's what with the watering!)
Next year we are going to look into more dwarf-ish / 5 feet max plants for containers... I kind of went crazy and put some frickin' 8 feeters into some containers. Teehee. It's nothing I technically regret yet, knock on wood, but I look over at my "Patio Tomatoes" and think they look like perfect bonzais. Uhh. If I can get similar yields off of smaller plants I think I should try that. And then save the 9 feet plants to go in the ground at my MIL's house, hah.
