My two plants are both big now and continue to add foliage. Small insects are feasting and there are a lot of small holes in the leaves. It doesn't seem to be a big problem. I've picked off and squashed a few small green caterpillars. I'm sure this will become a bigger problem as the warm season progresses but seems controllable.
The Better Boy has just started setting fruit in numbers, maybe 12-15 small green fruit so far.
The Celebrity is another story. It has about 25 fruit between 1- 4 inches in diameter that are developing rapidly and maybe that many more smaller fruit. It is still actively blooming. I have no idea how much longer it will be before the first fruits are ripe but it seems like it will be awhile. This plant will have a lot of fruit on it before any are ready to eat. I wonder how many fruit a plant like this can sustain at one time? It doesn't seem to be a problem now, they all seem to be getting bigger daily.
If it seems like problem later I may pick some of the larger green fruit off for a gallon jar of refrigerator pickles. I love green tomato pickles.
So far, all I've done is water them. Pretty good deal, unless I experience some unforeseen tomato catastrophe soon.
