Bill Johnson Community Activity Building, Roswell Area Park, 10495 Woodstock Rd, Roswell, GA. February is the ideal time to plan to treat your lawn turf - before weeds germinate. Beautiful, healthy lawns require more than simply mowing and fertilizing. Cool-season and warm-season grasses require similar activities, but at different times, to be effective. This class will cover how cool and warm-season grasses differ and what they require, soil testing, fertilizing, weed control, aerating and watering. Even if someone else takes care of your lawn, this seminar will enable you to work with your lawn service more effectively.
