For many decades Colorado Blue Spruce were a very popular choice for windbreaks in Iowa. Now a lot of those trees are dead or dying. On today's Talk of Iowa it’s Horticulture Day. D.N.R. District Forester Mark Vitosh of Iowa City and I.S.U. Extension Horticulturist Richard Jauron will be here. We’ll talk about planting new windbreaks and rehabilitating old ones. We’ll also be answering your questions about plants and trees. We look forward to your questions!
