I guess I will have to answer that next spring. lol
Seriously, we put 8- 4ft grow lights on our back porch along with some mega thick plastic sheeting and put our plants of all description there for the winter, which is short and mild here in SE Texas. We may use a heater there this year. We keep tropicals and succulents there without major problems. We should put them outside during warm sunny periods during cold weather, but it is a major effort to move them; we have a half dozen 20”- 24” containers and too many to count 12”-20” containers and my wife and I cannot handle them easily.
The maters, being food crop, may warrant in-house overwintering, along with my hot peppers.
rightly, if you can keep a tomato plant indoors in the house, then I could, too. You know I don't know a lot about plant life yet, but if I can root a tomato plant, when it gets cold, I'll just bring it in the house. How about a tomato plant for a center piece in the middle of the dining table, or, better yet, use one for a Christmas Tree. I think I just have a new Christmas Tree. I'll try to find a sucker tomorrow and get it in water.
I think my sister-in-law and her husband are going to come here Christmas, and they know I'm strange, but even they would laugh at a tomato plant for a Christmas Tree.
Thank you, thank you ALL, for all the information. Fascinating! I might try this.
