Check out the Guilford County Cooperative Extension's program, Beautiful and Sustainable Lawns - a Greener Yard! In the Piedmont, rejuvenating lawns is best done in fall. Knowing and using good growing practices all year also saves you time and money, and reduces environmental impact. Establishing a healthy stand of grass now with good planning and sensible management will minimize issues with weeds and diseases in the future - you can have a beautiful healthy lawn and also reduce the impact and expense of lawn chemicals.
