Transform thin, patchy lawns into thick, lush turf with professional overseeding from Greenlawn Inc. Fill bare spots, introduce improved grass varieties. Serving Howard County since 1986.
September and early October provide ideal conditions in Ellicott City—warm soil, cool air, adequate rainfall, minimal weed competition. Fall overseeding succeeds where spring seeding often fails. Book your fall slot now!
Overseeding spreads grass seed over existing turf to fill thin areas, repair bare spots, and increase density. Unlike seeding bare ground, overseeding introduces new grass into established turf—revitalizing lawns that have thinned from age, disease, insects, or stress.
Why lawns thin over time:
Replaces dead grass, fills gaps where soil shows through. Within 6-8 weeks, thin areas become thick healthy growth.
Thick grass = best weed prevention. Dense turf shades soil, outcompetes weeds, physically prevents establishment.
Modern cultivars offer disease resistance, drought tolerance, better color. Gradually upgrade without complete renovation.
Premium varieties handle Maryland summers better. Over 2-3 years, stress-tolerant grass increases significantly.
Genetic resistance to brown patch, dollar spot, leaf spot. Diverse genetics = more resilient turf.
Thick, dense, lush carpet-like appearance. Improved color and texture. Better curb appeal and property value.
By far the best timing. Warm soil speeds germination, cool air reduces stress, rainfall provides moisture, minimal weed competition, cool-season grass enters peak growth. Fall-seeded lawns establish strong roots before summer stress. Optimal window: September 1-October 15 (earlier = better).
Possible but problematic. Conflicts with pre-emergent crabgrass control (prevents ALL seed germination). If you overseed spring, must skip pre-emergent = crabgrass invasion while grass establishes. Spring-seeded grass has only weeks before summer stress = high failure rates. Wait for fall for better results.
Don't do it. Heat/drought make establishment nearly impossible. Poor germination in hot soil, seedlings struggle, excessive irrigation needed, high failure rates. Wait for fall.
Workhorse for Howard County. Excellent heat/drought tolerance, good shade tolerance, disease resistant, low maintenance, attractive texture. Handles Maryland climate best. We use blends of 3-5 cultivars for diversity.
Beautiful dense turf with self-repair. Ideal for sunny areas with good irrigation. Requires more water than fescue. Often blended 10-20% with fescue for best of both.
Most shade-tolerant grass available. For areas under mature trees where tall fescue struggles. Tolerates dry shade and low fertility better.
We tailor blends to your specific conditions. Typical: 80% tall fescue, 15% bluegrass, 5% fine fescue. Diversity ensures good performance across varying conditions.
Germination within 7-14 days of fall seeding. First notice tiny blades emerging (light green haze). By 3-4 weeks, new grass reaches 2-3 inches (clearly visible). Full establishment takes 6-10 weeks. Best results appear following spring/summer when established grass really thrives.
Yes, but results won't be as good. Less seed achieves soil contact = lower germination. Recommend power raking/vertical mowing if skipping aeration. However, combining services dramatically improves results. Aeration provides additional benefits beyond overseeding = worthwhile investment.
No. New grass grows alongside existing turf without harming it. Only weak grass might be outcompeted by vigorous new growth—but replacing weak grass is the goal. Overseeding is additive; improves what you have rather than starting over.
Depends on condition/goals. Severely thin lawns: annual for 2-3 years until density restored. Good condition: can skip years once thick. Many settle into every-other-year schedule. Lawns with ongoing stress (shade, traffic, disease) may need annual overseeding.
Stop tolerating thin, patchy turf. Professional overseeding from Greenlawn Inc transforms struggling lawns into thick, lush landscapes. Our 39 years serving Howard County means we understand exactly what grass varieties thrive in Ellicott City.
