Blue Grama grass is a hardy grass that is native to North America. It is intolerant of shade, needing full sun to thrive. Grama forms clumps when it grows and can be planted in most soil types. This grass tolerates drought, heat and cold. It looks the best when planted along with wildflowers. When sowing grama grass seed in the fall, it is essential to prepare the soil. Without proper site preparation, the grass does not have as high a chance of success. Start preparing the soil one month before planting grama grass seed.
Run a rototiller over the planting area to loosen the soil. You need air pockets beneath the surface for the health of the blue grama grass.
Kill weeds and other grass to prevent them from competing with the grama grass. Pull them by hand or apply an herbicide to kill them. Make sure you use a weed killer that targets annual and perennial weeds. Do it far enough in advance so that the herbicide does not affect the growth of the new grass.
Water the planting area until the ground is moist. Wait a couple of weeks to see if more weeds emerge. When you see them germinate, once again kill them with weed killer or pull them by hand.
Till the land 4 inches deep when you are ready to disperse the grama seed. Rake until level and smooth. Remove debris such as sticks or stones. Break up soil clumps that are larger than 1 inch in diameter.
Determine how much grama grass seed you need to cover the desired area. Use the seed bag to help with application amounts.
Fill a bucket halfway with sand. Add water to make it somewhat moist, but not wet. Pour in the desired amount of grass seed into the bucket. Combine the two thoroughly in the bucket.
Fill a hand spreader or mechanical spreader with the sand/seed mix. Broadcast it over the area evenly, making sure to cover the land completely. It may be a good idea to make two passes, to ensure even coverage.
Run the back side of a metal rake over the seed. This will cause it to be lightly covered with soil--1/4 to 1/2 inch is sufficient to cover the seeds and encourage germination.
Keep the grama grass seed moist. Water at least once a day, if not twice, until the grass is 1 inch high. Because you're planting after the heat of summer has ended, you should not need as much water as you would if planting in the summer.
