Kentucky bluegrass is a a cool-season, finely-textured perennial grass that is native to Europe. There are over 100 varieties of Kentucky bluegrass, with varying tolerances to heat, mowing height and shade. Richard L. Duble, Turfgrass Specialist with the Texas Cooperative Extension, suggests planting a blend of three varieties to ensure a successful lawn. Plant Kentucky bluegrass seeds in mid-September until the end of October.
Perform a soil test with a home testing kit or by delivering a soil sample to your county cooperative extension office. There is generally a nominal charge for the test, and the agent can supply you with suggestions as to the appropriate soil amendments.
Remove all weeds and other vegetation growing in the planting area. Pull weeds by hand if there are only a few weeds; otherwise, use a hoe.
Til the soil with a rototiller or shovel to a depth of 5 inches. Add any soil amendments recommended by the soil analysis and 10 lbs. of 16-4-8 fertilizer for every 1000 square feet of planting area. Mix the amendments and fertilizer into the soil to a depth of 4 inches.
Rake the bed until it is smooth.
Grade the planting area to direct water away from the home or other structures by laying a 2x4 on the soil, directed from the structure to the drainage area. Place the level on top and raise the end of the 2x4 that is furthest from the structure. When you get a level reading on the level bar, calculate the distance between the raised end of the 2x4 and the soil. Add or remove soil to create a gap of 2 inches between the raised end of the board and the ground.
Pour half the Kentucky blue grass seed into the broadcast spreader and sow it in north to south strips. Fill the spreader with the remaining seed and sow it in an east-west direction. This checkerboard pattern helps to ensure even coverage. Drag the rake lightly over the area so that the seeds are just barely covered.
Water two to three times per day for the first three weeks. Water until the top 2 inches of soil is moist. After that, provide 1 to 1 1/2 inches of water per week.
