I have noticed that tomatoes are highly capricious as to where and how they thrive.

One rooted Azoychka branch I planted just for tasting one or two fruits, is thriving and pumping out tomatoes in a very small pot. Probably root-bound, it doesn't seem to mind - it's flourishing and the leaves & new growth are green.
It doesn't seem to mind whether under-watering, over-watering or watering at all.

Some of my plants are in large containers, properly planted and fed, and they have been harassed with BER, blossomd drop, and they're very stingy on top of that...
Barely ten set fruits in a large pot that should give it plenty of room.

That brings me to believe that container size isn't everything... One can do their best and try to give plants ideal conditions - as good as possible within limits -, and still, there are other variables as to what happens and how much fruit the plant decides to give.
