Holly and Joey Baird, who have created the Wisconsin Vegetable Gardener, stop by to talk about their burgeoning horticulture empire north of the border and how to grow great tomatoes, among othe things. Mike talks live to a team of horticulturists in Dublin, Ireland, including Matt Barrett and Peggy Stewart from the Chicago Park District and grower Pat Fitzgerald of Ireland. Together they created an award-winning display called the Chicago Bridge the Gap Garden, which celebrates the connections between the Emerald Isle and Chicago. Michael and Amelia Howard join Mike in studio to promote a building fund for Eden Place Garden Center in Chicago's Fuller Park Neighborhood.
