That sounds like fun, breeding tomatoes for resiliency. I love fresh tomatoes. I had some growing this summer but they got some kind of blight disease and I had to remove them. They were also being attacked by a lot of thrips. I will be planting more marigolds with the tomatoes to help deter them if I do tomatoes again. I read that marigolds are good at repelling thrips.

Do you know about growing corn, beans, and squash together? It is what the original people of america grew together for more abundant crop in a smaller space since the plants work together. I am into companion gardening, as you can see.
