How to Grow Blue Grass


Blue grass, or Kentucky blue grass, is the most popular grass used for lawns in the United States. Although its name implies differently, blue grass is not native to North America. It was originally grown in Europe and brought over with early settlers. The grass is extremely easy to grow. It grows most vigorously in spring and fall when temperatures are moderate and water is plentiful. It is known for its vibrant green color and boat-shaped leaves. Although blue grass grows well, it is best to partner it with a companion grass to ensure a thick and healthy lawn.

Step 1

Select three different varieties of blue grass that are suitable for your area. There are more than 100 different varieties of blue grass that have been established. Purchase three varieties with different strengths suitable to your lawn.

Step 2

Pull up any weeds and clear your lawn of all vegetation. Use a tiller to till your lawn's soil. Wait one or two weeks and watch for any new growth of weeds or other plants.

Step 3

Spread blue grass seed across the lawn in an evenly-distributed fashion. Plant 2 to 3 lb. of seed per 1,000 square feet of lawn. Plant in spring if you have harsh winters, and in fall if you have hot summers.

Step 4

Water the ground thoroughly. The grass needs two to three waterings per day during the first two weeks. The easiest way to do this is to set a sprinkler out and turn it on once at breakfast, once at noon and once at dinner, moving the sprinkler to a different location each time. After the grass emerges from the soil, reduce the watering to once a day.

Step 5

Fertilize the lawn with a high-nitrogen, soluble fertilizer. During the first year, apply 1 lb. of fertilizer per 1,000 square feet in five to six applications throughout the year. After the first year, apply fertilizer two to three times per year.

Step 6

Cut the grass after it has grown more than 2 inches in height. Be sure your mower blades are extremely sharp, as a dull blade may pull grass up at the root instead of cut it. Cut the grass to 2 inches, and no lower. Short grass is susceptible to insect damage and disease. It is better to leave blue grass long than cut it too short.

Step 7

Use an insecticide should any insects, such as billbuugs, webworms and grubs, damage the lawn. Use herbicide to control any weeds.
