Cary, We recommend you transplant any indeterminate style tomato but any determinate or bush type will work great in the cage provided.
It would be nice if they put the 5 for $15 on a sign somewhere. Nice selection, I passed because everything was marked full retail. I have other options that are free.
I don't know about a warranty, however, I have had fantastic luck with these tomatoes. It sounds like they got cold. Try putting them in new potting soil and try to find a little warmer area, also some sunshine. Should do okay.
Cityfarmer, This tomato will need to be transplanted into a larger container soon. You can still keep it in doors in a sunny spot. They require 6+ hours of sun a day. A Better Boy Tomato will not be a good choice to grow indoors due to they can reach 7ft. high.
It's the diameter of the top of the pot.
Get it in the ground if there is no longer a chance of a freeze, and be sure your soil is ready - - a good fertilizer or compost or whatever is needed in your part of the country to replenish soil nutrients. If weather is "iffy," add a bit of good potting soil to the poor baby until it can be planted. Tomatoes are pretty hardy, so it should survive, if not exactly thrive, until it goes in the ground.
Contact the Agriculture agent from your local University/ extension or Co-op on this one. He/she will know your local plant diseases and to prevent them. I was separate to save my yellow tomatoes two years ago, and an extension agent from Texas A & M was so helpful!
We estimate 78 days after planting our transplant. You can find more information in this link: https://bonnieplants.com/product/big-boy-tomato/
