In a lot of parts of the northern tier of the United States, it has not been a good year for tomatoes...so far. We never know what Mother Nature has in store, especially in the era of climate crisis, but that doesn't stop people from planting their Brandywines, Cherokee Purples, Wisconsin 55s and Green Zebras. Mike and Peggy talk to two nationally recognized tomato breeders--Craig LeHoullier, author of Epic Tomatoes: How to Select and Grow the Best Varieties of All Time, and Keith Mueller, who has been working with the Seed to Kitchen Collaborative at the University of Wisconsin, among other groups. Their nicknames are, respectively, "NC Tomatoman" and "KC Tomato."
