Conditions have been perfect for growing lush, green grass this summer, though weeds have been thriving as well. Host Charity Nebbe discusses summer lawn care with Nick Christians, professor of horticulture at Iowa State University. Christians has developed an organic herbicide using corn gluten meal. Horticulturist Richard Jauron also joins the program.
