Blue grama is a type of grass that is most frequently grown in the Southwestern region of the United States, though it can be cultivated in the Great Plains states, as well as Mexico and some southern areas of Canada. When planting this variety of bunchgrass, it's important to ensure that the seeds have a temperate climate in which to flourish. The best time of year to plant blue grama seeds is late spring or early summer, when night temperatures remain above 60 degrees.
Remove any existing grass, if applicable. Apply a spray-on herbicide to the lawn and wait for about a month for the grass to die. Rake or till the dead grass into the soil.
Weed the area where the grass seed will be planted. Pull all weeds by hand or, if you have a bit more time, apply a coating of spray-on herbicide to the land. Wait 10 to 14 days, then rake up and dispose of the dead weeds.
Till the ground about three inches deep, removing any rocks, roots and other debris. These items can keep the blue grama grass seed from taking root. Rake the fluffy soil, covering it with evenly-spaced shallow furrows.
Determine the amount of grass seed required for your lawn. Usually, three to four pounds of grass seed are required for every 1,000 square feet of land.
Fill a bucket halfway with slightly damp sand. Add the grass seed to the sand, then mix. The sand weighs down the seed, allowing it to remain where it is deposited until it takes root.
Evenly scatter the grass seed by hand across the prepared area. Smooth the seeded ground with the flat back of the gardening rake's head. Drench the seeds with water; the ground should be wet to a depth of four to six inches.
Water the seeds twice daily until the grass has sprouted. Blue grama grass seed requires about a week to germinate. Reduce the watering schedule gradually after that, taking it down to once every two or three days. A month after planting, the blue grama grass should only require watering once a week.
