@toolmania1 YOU ASKED whether you should dump them or try and overwinter them, right?
We gave you good advice, yet you quote some youtube video to argue that you CAN overwinter them.
If you want to struggle along pampering your tomato plant indoors over winter, go right ahead. Why bother asking any of us, then? We aren't agreeing with you, accept that and do as you please.
It's a futile effort because seed planted in pots inside in January in Jersey (or anywhere else) or bought at a garden store will out-do any plant you choose to overwinter. Just because you read that some guy overwinters his does not mean that overwintering is better than starting with a new tomato plant.
But hey, what you do with your time is your business.
To everyone else: Dump your old tomato plants and plant new in spring.
