Has anyone here have any experience or ever seen or heard of this being done? I am going to try to graft together one or even two plants to one main stalk in order to gain root system as an experiment. Then I would prune the plant to raise 5 or 6 tomatoes in order to see if the plant would produce very large tomatoes. This is different from grafting a cutting..kinda. I believe the ripening stage is somewhat determined by the plant and tomato genes.
