Blue Panther® Kentucky Bluegrass Grass Seed

Jonathan Green Blue Panther® Kentucky Bluegrass Grass Seed grows a sod-quality lawn from seed. Use this seed mixture to overseed a thinning lawn that was previously planted with Kentucky bluegrass sod. Blue Panther® contains the very best Kentucky bluegrasses currently grown by leading sod growers and on golf courses across America. 

Blue Panther lawns are dark-green in color, very uniform in leaf texture, and can withstand high traffic. Kentucky bluegrass has a horizontally spreading rhizome root system which results in bare spots being filled in, thickening the entire lawn. Use our Blue Panther® when you want to keep a 100% Kentucky bluegrass lawn. This seed germinates in 21 – 28 days.

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

Prepare: 

• Mow – Mow the lawn at the lowest mower setting before seeding to allow the 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. The 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.

Seed:

• 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. 

Maintain:

• Water – For best germination, water daily to keep the seedbed moist. 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.
