I planted tomatoes in containers outdoors, and only got 3 or four tomatoes. So I cut off a healthy looking section of an indeterminate one that was still alive, about 3 weeks ago, stuck it in fresh potting soil and peat moss, in a new planter, and kept it watered. So far I have 2 tomatoes and more flowers forming. I’m going to move it indoors if heavy frost is indicated, but here in NE Oklahoma, we may get a frost, the get up to 70 or 80 the next day, so I’m hoping I can get a good producing plant before it gets cold.
If you can keep it where temps are 50 degrees and above and keep it in full sun, it just might work!
I’ll post pictures later of my unheated ‘greenhouse’ experiments that I’m starting up here on The Frozen Tundra.
We had temps in the 40’s last night...but it was worth the crystal-clear sky and the Milky Way visible right above me! :)
This should work. Just prior to the first frost, I have cut off branches that had tomatoes and/or flowers and stuck them in a couple of big pots.
Most survived-the tomatoes ripened, and many of the flowers formed new fruits. I pulled a couple of the best branches out and kept them going all winter in a sunny place. Slow but continued to produce flowers and fruit all winter.
Each joint is capable of forming roots.
