You say tomato, I say to-mah-to, you say cherry, I say roma--on today's Talk of Iowa, it’s Horticulture Day. The most popular homegrown vegetable is, of course, the tomato. We’ll talk about selecting varieties, planting and caring for tomatoes with horticulturists Richard Jauron and Linda Naeve of Iowa State University Extension. We'll look forward to your calls, too.
