The Annual Battle Against Pond Scum

Put heat, light, water and nitrogen together and you get lakes and ponds that are choked with plant growth.  It's Horticulture Day and host, Charity Nebbe, talks with Allen Patillo, Iowa State University Extension Fisheries and Aquaculture Specialist about aquatic plant management.  Later in the hour ISU Extension Horticulturist Richard Jauron and DNRDistrict Forester Mark Vitosh join the conversation to answer listener questions about plants and trees.
