Along with Iowa' s more traditional crops, two species of cucumber vines are having a bumper year. You won't find them at the farmer's market though, because they're weeds. The light green vines can grow as long as 30 feet and will coil around anything they touch. They've been showing up in windbreaks in Iowa, Wisconsin and Minnesota. Iowa State University Agronomy professor Bob Hartzler says the vines are very aggressive and will return year after year.
This is the season for planting, and next comes the season for fighting weeds. Today on Talk of Iowa, it’s Horticulture Day. Bob Hartzler, an ISU extension weed specialist joins the program to talk about doing battle with volunteer trees and invasive species like multiflora rose and honeysuckle.
