Ask Mr. Smarty Plants

Mr. Smarty Plants believes that your best bet would be to choose from native bunch grasses that grow well in your area.  They may not be quite as fast and effective as turf grasses, e.g., Bermuda or carpet grass, in choking out weeds, but they would not be invasive into flower beds.  A number of potential choices are listed in this web site for Piedmont grasses,  I would suggest Schizachyrium scoparium (Little bluestem), Aristida purpurea (Purple threeawn), Muhlenbergia capillaris (Gulf muhly) or a mixture of these for the sunny areas of your lot.  A lower-growing, somewhat weedy choice would be Paspalum setaceum (Thin paspalum), which will grow in full sun but prefers partial sun.  For the shady areas near the woods, Chasmanthium latifolium (Inland sea oats) would thrive.  Seeds of these species should be available from local suppliers, such as Rock Spring Farm, or Native American Seed.  The preferred time for planting the seeds is spring.  Till the soil no deeper than two inches; rake level, and roll the soil lightly to make the bed firm. Remove all existing weeds. Because tilling often stimulates weed germination, it is advisable to water the bed one to two weeks before planting. This encourages weed germination. Weed seedlings can be killed by hand-pulling, laying a sheet of plastic over the weeds until the sun cooks them out, or by using a post-emergent, non-residual herbicide. You may need to repeat this procedure several times to ensure a clean bed. Starting with a clean bed is much easier than eliminating weeds after planting.  Planting can be done by hand-broadcasting or with a garden planter. If you hand-broadcast seeds, be sure to distribute them evenly, then cover the seeds with one-half inch or less of soil or a light layer of compost. This can be accomplished by raking in two different directions in loose topsoil.  Water new plantings regularly to assure germination and root establishment. Optimum growing temperatures are 80 to 95 degrees Fahrenheit during the day, and around 68 degrees Fahrenheit at night.
