AnnofPA I use to read an article , from Penn, Where an older farmer /Market Gardener would save a few tomatoes , Then would make small hills , Shallow plant the whole small tomato or pieces of a larger type I believe
He would winter sow them at the end of the season that way for his later season tomatoes ,
kqcrna One of the few times I ever saw a perennial Tomato was in Ohio , lived about five years , a larger Beefsteak type , I still wish I knew what they were ,,
