Jonathan Green Black Beauty Keystone PA Grass Seed (7 lb) – Cool Season Lawn Seed

Overview

Built for Pennsylvania lawns, the Jonathan Green Black Beauty Keystone PA Grass Seed combines a climate-tuned cool-season mix with a rich, dark-green appearance. This 7 lb bag is designed to deliver dense turf that remains visually appealing under foot traffic and seasonal changes. The blend includes tall fescues, perennial ryegrass, and Kentucky bluegrass, providing a balanced foundation for a resilient lawn that remains inviting through the seasons.

Ideal Growing Conditions for Pennsylvania Yards

• Timing matters: apply from mid-August to mid-October while the ground is warm and nights start to cool.
• Moisture management: a deep root system and a waxy leaf coating help retain soil moisture during establishment.

What You Get with Black Beauty Keystone

• A dark-green, dense lawn with a refined texture that looks uniform across the turf.
• Good performance in full sun and partial shade, plus notable heat and drought tolerance for Pennsylvania summers.
• Strong wear tolerance, supporting lawns that see foot traffic from families and pets.

Coverage, Germination, and Use

Each 7 lb bag seeds a new lawn up to 2,625 square feet. For overseeding, expect coverage up to 5,250 square feet. Germination typically occurs within 10–14 days, depending on moisture and temperatures.

How to Apply with Confidence

• Prepare a smooth, well-draining seedbed and loosen compacted soil for better root penetration.
• Spread evenly and lightly rake to incorporate seeds into the soil surface.
• Water consistently to keep the topsoil moist during the first two weeks of establishment.

Whether restoring a worn area, overseeding a thinning lawn, or starting fresh, this Keystone PA seed mix is designed to support a balanced, green lawn that can adapt to Pennsylvania’s seasonal rhythms. The blend’s deep roots and moisture-retentive leaves contribute to a lawn that looks good and performs well in everyday settings—playtime, weekend yard chores, and quiet evenings outdoors.
