How to Plant Kentucky Blue Grass


Kentucky bluegrass is a popular choices for yards and lawns throughout the United States. It's a cool-season grass that grows best in the spring, fall and winter. In the summer, it grows more slowly. It can tolerate the weather conditions in much of the United States, but it does not always grow well in parts of the country with hot, dry summers, such as the Southwest. Kentucky bluegrass from seed takes several weeks to germinate and begin to grow in. During this time, it's important to maintain the seed properly so it does not die.

Step 1

Apply a high-phosphorus fertilizer to the surface of the soil where your Kentucky bluegrass seed will be planted. Make sure your fertilizer does not contain any weed-killing chemicals, because they could interfere with the grass growth.

Step 2

Spread the seed over the area where the grass is to be grown. Use a wheeled seed spreader or a hand caster to help speed the process and ensure the seed is evenly spread.

Step 3

Rake the top surface of the soil to help work the seeds into the dirt. Rake only the uppermost layer of soil--about 1/8 inch.

Step 4

Roll over the newly laid seed with an empty lawn roller. This will ensure the seeds make proper contact with the soil so they can germinate.

Step 5

Spread a thin layer of peat moss over the seed. This will help cover the seed and protect it from being blown away or otherwise disturbed. If you don't have peat moss you can use another organic material, such as sawdust. Skip this step if windy or breezy conditions are not a concern.

Step 6

Water the lawn immediately after the seeds have been planting, and water two to three times each day for about two weeks.

Tips and Warnings

  • Do not plant grass seed on a windy day. The wind may blow the grass seed off the soil, and your grass may grow with gaps or holes.
