Invasive Plant Management Workshop

Many people in southeastern Wisconsin work to control exotic invasive plants in our natural areas. SEWISC is teaming with Johnson’s Nursery, Inc.TM to offer our Invasive Plant Management Workshops twice annually. Take this class to ensure that you are using the most appropriate, efficient, up-to-date, and least environmentally damaging methods in your control efforts.
