I need to read this thread more thoroughly but will tell you what I observed. I walked down to my neighbors to see how her tomatoes were doing and they looked OK but there was one that was huge with lush green foliage and lots of small fruit setting. Way more vigorous than any of her other plants. The tag read Mighty Mato Grafted, I was interested. When I looked closer I found out that it was Pink Brandywine. She said she had bought it at a local nursery that I missed this year so I will look next spring and try some grafted if I can find them. I told her that I was going to come down and swipe one when they are ripe......I will share mine with her as I will have ripe ones before she will. Something to anticipate. I will take a picture when the light is better......Anyone growing grafted this year?
