As the technician for tomatoes here at Johnny's Selected Seeds and owner of my own small certified organic produce farm, I have been grafting tomatoes and other crops now including cucumbers, peppers, and eggplant, for the variety trials at Johnny's and my own farm. I would be happy to discuss the grafting process, ideally with some seedlings to demonstrate on, and discuss the benefits and drawbacks of the process, variety selection, question and answer, etc.
