Horticulture Day: Plant Hardiness Zone Map

"Punxsutawney Phil" may have predicted six more weeks of winter, but we all know that gardening season is just around the corner. It's Horticulture Friday today, and Charity looks at organic gardening and the new Plant Hardiness Zone map from the USDA. We'll find out why you might not want to invest in too many "Zone 5" plants just yet. Guests are Richard Jauron, Iowa State University Extension Horticulture and Kathleen Delate, Prof. of Horticulture at ISU.
