Jonathan Green Black Beauty® Ultra Grass Seed mixture combines our most elite Black Beauty® tall fescue seed varieties with our best Kentucky bluegrass to fill in bare spots quickly and invigorate worn out lawns. Black Beauty® Ultra also contains premium perennial ryegrass for fast germination and wear tolerance in lawns that experience heavy traffic. The Black Beauty® Ultra seed grows naturally dark-green turf and is most similar to the Black Beauty® seed mixtures that sod growers purchase from us to grow high-quality sod within one year. This seed germinates in 7-14 days.

For the best results, follow the directions below for establishing a new lawn or overseeding an existing one.


  • Mow - Mow the lawn at the lowest mower setting before seeding to allow seed to reach the soil.
  • Rake - Rake over the existing grass with a metal rake to remove the thatch layer and any debris to loosen the soil. Add additional topsoil to fill in holes and level the ground.
  • Check soil pH level - Have a soil test taken to check your soil’s pH level. Optimum soil pH should be between 6.2 to 7.0. For a pH below 6.2 use Jonathan Green MAG-I-CAL® Plus for Acidic & Hard Soil to rapidly increase pH. If the pH is above 7.0 use MAG-I-CAL® Plus for Alkaline & Hard Soil to rapidly decrease the soil pH.


  • When to apply - The best time to apply seed is mid-August to mid-October while the ground is still warm and the nights are cooler. Mid-March through mid-May is the next best time to plant, when the soil temperature reaches 55º+ Fahrenheit and the temperature of the air stays consistently warm.
  • Spread seed - Apply half of the seed with a rotary spreader in one direction (north to south) and the remainder in the opposite direction (east to west). It is beneficial to spread a new seeding fertilizer that is high in phosphorus at this time as well.
  • Rake seed - Rake lightly into the ground with a metal rake. Walk with light, even footsteps on the seedbed to firm the soil around the seed. Do not bury the seed more than one fourth of an inch deep.


  • Water - For best germination, water lightly each morning to keep the seedbed moist. In sandier soils that dry out quickly watering more than once a day may be needed. Continue watering regularly for a few weeks until the grass plants reach a height of 2 - 2.5 inches.
  • Mow - Begin mowing when the new grass has reached a height of 3 - 4 inches. Make sure the mower has sharp blades. Be careful not to scalp the lawn, low mowing will stress the root system and encourage the growth of weeds.
