The varied climate of the Northern Virginia region means local homeowners face challenges in cultivating their lawns due to the seasonal extremes typical of our transitional zone. Choosing the right turf grass variety to survive the cold, windy winters and the humid, steamy summers can be challenging. Warm season grasses tend to go dormant from mid-fall to late spring, turning a straw-like color after the first frost, while cool season grasses can struggle in the summer heat and possibly go dormant during prolonged droughts.
In our over 30 years of experience seeding and caring for the lawns of Northern Virginia, our chief agronomist has determined that cool-season grasses, particularly tall fescue varieties, thrive best in our regional transition climate. The Virginia Cooperative Extension recommends tall fescue as well, and other cool season grass varieties such as Kentucky bluegrass and perennial ryegrass. The Virginia Cooperative Extension also recommends seeding with multiple varieties to encourage turf survival through genetic diversity, which is why Bio Green developed the Bio Green Elite Custom Blended Seed – designed and proven to thrive across Northern Virginia lawns.
Cool season grasses such as these experience growth in both spring and fall but germinate and respond best to fall weather conditions. The soil temperatures and precipitation levels make September through mid-October the perfect time to seed or reseed your lawn for optimal growth. Once you’ve prepped your planting ground, either by tilling loose soil or mowing your existing lawn to about 1 inch high, then topdressing as needed, you’re ready to begin.
To avoid light or heavy seeding, the Virginia Cooperative Extension recommends using a slice seeder or drop spreader. Under seeding results in grass that is thin and clumpy, while heavy seeding produces an overcrowded lawn with poor roots that is more vulnerable to disease. Your seeding rates will also depend on the variety of turf grass chosen, so use the manufacturer’s instructions for seed application rates.
Once planted, your seeds will require consistent moisture to prevent them from drying out. Wet the seeds immediately and thoroughly after planting, following with light watering as frequently as needed to keep the soil moist, but not saturated. This may require watering up to twice a day until germination. Water as needed in accordance with milder, fall weather that brings increased, steady rainstorms. After the seeds have germinated, water less frequently but increase the duration, watering deeper to encourage root growth.
To encourage a flourishing lawn, your choice of seed heavily dictates your success, even with the proper planting and watering techniques. To learn more about the proven success of Bio Green’s Elite Custom Blended Seed, visit our website.
