Best Grass Seed for Full-Sun Westchester, NY Lawn

Kentucky Bluegrass: The Gold Standard

For a Westchester lawn with all-day sun and only light late-morning shade, Kentucky bluegrass (KBG) is the top choice. Modern cultivars have overcome historic weaknesses:

• Aggressive rhizome spread for self-repair.
• Improved disease resistance (summer patch, leaf spot, necrotic ring spot).
• Tolerates lower mowing (2–2.5 inches) and moderate traffic.
• Deep green color, fine texture, excellent cold hardiness.

Buying Tips

• Look for named cultivars (e.g., ‘Midnight’, ‘Beyond’, ‘Award’) on the tag—not just “Kentucky bluegrass.”
• Buy from reputable online seed suppliers (e.g., Seedland.com) for wider selection and freshness.
• Blend 2–3 KBG cultivars for genetic diversity.
• Add 10–15% perennial ryegrass for quick cover while KBG establishes.

Establishment

Seed late August–early September. Keep seedbed constantly moist. Fertilize with starter fertilizer (high P) at seeding, then again 4 weeks later. Mow when grass reaches 3 inches.
