Kentucky bluegrass is commonly used throughout the United States. It prefers cooler seasons, so it doesn't do as well in hot areas like California as it does in other states. Kentucky bluegrass prefers full sun, but can be grown in areas with some shade. To plant Kentucky bluegrass, it's important to prepare the site to ensure the grass seed will germinate well. It's not as simple as dropping the grass seed down and waiting for it to sprout.
Prepare the planting area. Use a garden hoe, rototiller or shovel to loosen the top few inches of dirt. Remove branches, debris and weeds so the Kentucky bluegrass seed can root better.
Break up soil clumps that are larger than 1 inch in diameter. Leave small clumps alone. The soil needs to be as smooth as possible for the seed to germinate.
Drop Kentucky bluegrass seed with a lawn spreader or mechanical spreader if you are planting in a large space. Use a hand spreader or drop the seed by hand in small areas.
Drop between 15 and 20 seeds per square inch of land. It's not necessary to count out the seeds, but use this as a reference. Dropping too few seeds will result in a sparse looking lawn, and too many will cause the grass blades to fight for nutrients.
Rake the soil lightly to cover the grass seed with a 1/4 inch of soil.
Water the Kentucky bluegrass every day to keep it moist and encourage rooting. Do not over-saturate it, or you'll cause the seed to wash away. Continue with daily waterings until the lawn is 2 inches tall.
