Anyone ever done this with a favorite Tomato plant? I bought a few romas from lowes this year and one is 3 times the size of the others and the fruits are twice as big as I am getting off of the others. It is a hybrid so I cant save seed from it but though I could take cuttings and over the winter make as many as I will need for next year and just grow out that one type of roma. How long could you keep a plant like that going? Years? I have to bring it in in the winter, would it do ok in a south facing window or do I need a light?
