How to Grow Blue Grama


Blue grama is a variety of bunchgrass that is naturally most prominent in Arizona and New Mexico, though it can be grown in most of the United States and southern areas of Canada. Because blue grama grows naturally in dry areas, it does not require particularly nutrient-rich soil to flourish. The grass does better in warm climates, so it's best to plant in the late spring or early summer, when temperatures have stabilized and frost is no longer a threat.

Preparing the Lawn

Step 1

Remove weeds from the lawn before planting the grass seed to ensure you get an even blue grama growth across the whole area. Pull up all weeds by hand or, if you have time to wait, spray the entire yard with an herbicide spray. Wait 10 to 14 days, then rake up all the dead weeds and dispose of them.

Step 2

Remove the existing lawn, if applicable. Spray the entire lawn with herbicide spray, then wait about a month to give the roots a chance to die. Use a tiller to mix the dead grass into the soil. Do not attempt this process with live grass, as it will just re-sprout along with the blue grama grass.

Step 3

Use a tiller to loosen the top three to four inches of soil on the cleared lawn, and remove any rocks and roots that you find.

Step 4

Comb the tilled soil with a rake to created furrowed rows throughout the planting area.

Planting the Grass

Step 1

Fill a bucket halfway with slightly damp sand. The sand decreases the fluffiness of the seed, making easier to distribute evenly across the lawn.

Step 2

Add the blue grama grass seed to the bucket and combine thoroughly. Use three to four pounds of grass seed for every 1,000 square feet of planting area.

Step 3

Scatter the seed mixture over the cleared lawn by hand, then turn over the rake and use the blunt end of the head to smooth the dirt. This will help cover the blue grama seeds, giving them protection while they sprout. Water the sown seeds thoroughly, so that the dirt is wet about four inches deep.

Step 4

Water the seeds lightly twice a day until they have germinated, a process that should take seven to 10 days. If the grass hasn't sprouted within a month, it may be necessary to re-plant. Cold and windy weather can disrupt the germination process.

Step 5

Care for the germinated grass by watering once a day for the first 10 days, then reducing the frequency to once every two or three days for the remainder of the month. After a month, the grass should be secure and will only require watering once a week.
