You've selected the right plant for your landscape, picked a good spot and planted it well, but your work is not done. On today's Horticulture Day program, we'll look at ways to keep your plants and trees healthy. Including identifying insect or disease problems, why proper pruning is essential and how to avoid stressing your plants and trees. Charity's guests are Iowa State University Extension Horticulturist Richard Jauron and D.N.R. District Forester Mark Vitosh.
