I dug up two healthy tomato plants in my garden trimmed them back and planted them in my double 5 gallon buckets. I have a sliding glass door that faces the south and going to try to keep them going this winter. Fresh tomatoes at Christmas sounds good.
Wow.
Good luck with that !
I always believed tomatoes just “ran out of gas” in the fall and couldn’t last.
Inderminate tomatoes will continue indoors just fine. I have done something similar several times. In my case, I went out the night before a frost, and cut all the branches off the tomatoes that had flowers or green tomatoes.
Stuck them all in a bucket of dirt and brought them indoors, and kept them watered. They didn’t all survive, but enough did to form new roots, and then got even more flowers to make even more tomatoes.
I also turn the grow light on when the sun goes down till around 8 or 9 o’clock just like it was summer time. I did dig up a pepper plant one year and it did fine too. Fresh peppers and tomatoes for organic Vitamin C all winter. LOL
My tomatoes that I over-winter usually produce 6-8 new tomatoes after coming in but I think the short day length shuts them down. Ours stay on a balcony with windows on the north, west and south.
