Cover the seed lightly and keep the soil moist until they start sprouting. This will increase the germination rates.
Similar to other cool-season grasses, Kentucky bluegrass grows significantly slower during the hot months. Extreme heat causes the grass to go dormant. But, it can recover easily with irrigation or when weather conditions return to normal. Since the grass spreads and repairs from foot and vehicle traffic quickly, Kentucky bluegrass is a common choice for high-traffic lawns, golf courses, and sports fields.
For most people, Kentucky bluegrass is synonymous with the perfect lawn. When grown in its preferred conditions and given proper care, the grass produces a lush, dense, and long-lasting lawn that lives up to its reputation. Table of Contents show. Why Is the Kentucky Bluegrass Popular? How to Ensure Kentucky Bluegrass Spreads. By following a watering and fertilizer schedule for Kentucky Bluegrass, you will maximize grass growth and spread.
Poorly maintained Bluegrass lawns may struggle and spread more slowly. Provide your Bluegrass lawn with the essentials and you will be rewarded with impressive growth through spring, summer, and fall. Kentucky Bluegrass will send out rhizomes and spread on its own as long as it is fertilized, kept from suffering drought, and is maintained with regular mowing.
This is in direct contrast to Rye and Tall Fescue, which are the other common turf grass varieties in regions where KBG grows. These grasses grow in bunches and new seed must be cast to encourage spread. Look for new sprouts filling in your lawn in spring and late summer. Kentucky Bluegrass will fill bare spots in your lawn naturally.
Damage caused by traffic, pet use, or excavation will be reclaimed as Kentucky Bluegrass sends rhizomes into the soil. If your lawn has small bare spots where grass has been damaged, you can encourage Kentucky Bluegrass to fill the area quickly through cultivation, watering, and mowing.
Reseeding is only necessary for bare spots larger than 24 inches 60 cm in diameter. Kentucky Bluegrass spreads faster than other turf grass varieties grown in the same climate. Kentucky bluegrass grows best in fall weather which is also the time you should first plant the seeds.
Ideally, the soil temperature is between 50 — 65 degrees Fahrenheit. Since germination takes longer compared to other perennial cool-season grasses, you might want to start with sods. This speeds up the establishment of Kentucky bluegrass.
As mentioned, Kentucky bluegrass does not do very well in shady weather so it is a good idea to mix the seeds with another more shade-resistant variety. Examples include rough bluegrass and perennial ryegrass. This species needs at least 1 inch of water per week, from either the sprinkler or rainfall.
In the warmer states, you should increase this to a 2 inch level to make up for the warmer temperatures. Once it has established, keep the grass mown at a height of at least 2 inches.
Going below this damages the seedlings so make sure the lawn mower is set to an appropriate height. Also, this species easily builds up thatch which can smother the younger blades. It is better to bag your clippings to prevent too much thatch buildup. This type of lawn should be fertilized 3 — 4 times per year with 3 — 5 lbs of nitrogen per square feet.
The exact amount will depend on how fertile the soil is and how easily weeds grow in the area. Kentucky bluegrass needs 2 — 5 weeks to fully establish. Once it has properly spread throughout the lawn, you should keep it at a height of 2 inches.
