How to Grow Sandberg Bluegrass


Sandberg bluegrass is a cool season perennial bunch grass. Its large fibrous root system makes it ideal for dry areas that receive little rainfall. It grows naturally on dry rocky slopes at elevations of 2,000 to 4,000 feet. As an ornamental grass, this drought-tolerant grass requires little care other than constant watering from the time of planting until young roots are established. Its finely textured foliage greens up early in spring and reaches a height of 12 to 18 inches.

Step 1

Select a sunny location with well-drained soil. Sandberg bluegrass is tolerant of sandy soil, but also performs well in loamy soil as long as it is well drained.

Step 2

Prepare the soil by tilling to a depth of 8 to 12 inches. Remove rocks, sticks and other plant debris and rake smooth with a garden rake. Sandberg bluegrass does not require additions of organic matter or fertilizer; however, amendments to improve drainage may be necessary.

Step 3

Plant Sandberg bluegrass in the spring while the weather is cool. According to a study published on the American Society of Agronomy website, ideal temperatures for seed germination range from 60 to 75 degrees F, but it will germinate in temperatures between 28 and 95 degrees F. Higher soil temperatures may cause bluegrass seed to go into dormancy. Early planting, especially in southern areas, is recommended.

Step 4

Sow seeds to a depth of ¼ inch and cover with soil. For mass plantings, seed may be broadcast over a wide area. For ornamental specimen plants, space 12 to 18 inches apart. Firm down with your hands to remove air pockets and settle the seed. Water to moisten the soil.

Step 5

Keep the area moist until seedlings emerge and roots have becomes established. Dry sandy soil may require light watering several times a day to keep seeds moistened. Do not allow seeds to dry out. Germination time depends on soil conditions and may take 21 days or more.
