I am growing two Better Bush in containers this year; my first attempt with this variety. Mine are right at 48" tall and have been producing well also. The info I read about them online suggests that they don't need to be staked, but after buying the plants at Costco in the last week of March, I went to Home Depot and bought a cage for each, along with three stakes.
When I bought them, they were already in blossom and had about 10-20 pea sized tomatoes on each plant. They came in 3-Gal pots so I transplanted them into 5-Gal pots, adding a good organic mix with about 30% Vermiculite and topped with bark after watering them in. My first fruits were a bit small, but they have been averaging in size now about 4- inches.
I grew Better Bush last year. I was impressed, too. They were in a constant state of production all the way through the summer and fall, and the tomatoes were huge for such a small plant. Mine went all over the place, though. I tried staking them, but they just did their own thing
They're a hybrid. I thought they'd make a great container tomato. Mine never got over 3' tall, maybe less.
