Blue grama grass is known for its lovely "eyelash" seed heads and can reach heights of 15 inches if not moved monthly. The grass thrives in most soil types, including clay and sand, and it is ideal for both larger lawns and as an ornamental grass. To increase its visual appeal, plant blue grama along with buffalo grass or wildflowers. Planting blue grama grass plugs produces a beautiful, soft lawn in zones 3 to 10.
Prepare your blue grama grass plugs for planting by watering them thoroughly and then making a shallow 1/8 inch cut through the roots on the bottom and on each side of the plug.
Leave the plugs in a location that receives partial to full sun during the mornings and partial shade in the afternoon for at least 1 week. This will help harden off the plugs.
Prepare the soil for planting by loosening it with a rototiller, watering it, and then exposing it to sunlight for several days. Add approximately 2 lbs of superphosphate per 100 square feet of soil, and then lay down 2 to 4 inches of compost.
Water the prepared soil about 3 days prior to planting. This will settle the soil and make certain your soil improver is well mixed.
Dig holes for your grass slightly larger than the plugs, place the plugs into the holes, and then fill around the plugs with loose soil. Plant your blue grama grass plugs 6 inches apart, keeping to a grid pattern.
Water thoroughly and frequently until your grass becomes established. You want the soil to remain damp without becoming muddy. Gradually reduce watering frequency as the grass matures. Established blue grama grass is drought tolerant, and may require watering only during the summer months.
Add at least 1 inch of mulching material to discourage weed growth and prevent moisture from escaping the soil too quickly.
Weed the lawn frequently by hand or with a broadleaf herbicide. Unchecked weed growth can quickly smother blue grama grass plugs, resulting in browning, poor growth or death.
Fertilize your grass plugs once or twice a month until they have grown together. If you planted the plugs during the fall, wait until early spring to being fertilizing. Established grass may only require fertilizing once or twice each year. Use 20 lbs of 5-3-1 fertilizer per 1,000 square feet of blue grama grass.
