I overwintered an eggplant last year, a Black Beauty. It never seemed to take off when re-planted in the spring. Also, I suspect that it overwintered some pathogens since all my eggplants seemed to get hit earlier than usual last year.

However, last year was a bad year all-around in my garden, so who knows. I'm in a warmer climate anyway, so I have a pretty long season for eggplant. It may be more worthwhile where you are.

I want to try to overwinter a plant that is still in the pot. I need some guidance. Thanks

I had good luck with a pepper plant in a pot. Put it in the sunniest window you have. You may not have to water as much, depending on how hot and dry your house is. Mine didn't bloom or fruit inside.
