Muhlenbergia rigens

Deergrass (Muhlenbergia rigens) is an evergreen grass native to the dry, temperate climates of western North America. Its spiky blue-green foliage has unique bluish-purple blooms that emerge in mid-summer. Deergrass is an excellent choice for erosion control, wind barriers and natural fencing. It is drought tolerant, thrives on sun to partial shade and requires little maintenance. Deergrass grows best in well-drained soil and can attain heights of up to two feet when low water is given. It can also be used as a ground cover or in a garden border. Deergrass is an excellent choice for a low-water, easy-care lawn.

watering

Deergrass (Muhlenbergia rigens) should be watered weekly, using about 1 inch of water per week. This should be done early in the morning or the evening, and allowed to dry between waterings. During the hottest part of the summer, deergrass should be watered more often (up to 3 times a week), as long as the soil does not become overly saturated. In general, however, deergrass is very tolerant of heat and drought, so be sure not to over-water.

sunlight

Deergrass (Muhlenbergia rigens) prefers sun exposure for 6-8 hours per day. The plant should be placed in an area where it receives direct sunlight in the morning and partial shade in the afternoon to protect it from harsh sun exposure and heat. Deergrass can tolerate some light shade but its flowering and growth will be reduced if it does not receive enough light.

pruning

Deergrass (Muhlenbergia rigens) should be pruned twice a year - once in late fall and again in early spring. Pruning in the fall helps to encourage good air circulation but may also cause some damage to the plant. In the spring, prune dead shoots or regions that are overcrowded. Focus on cutting the plants back near the base, rather than removing whole stems. Late spring is also an ideal time for “shaping” deergrass, making it look tidy and attractive. Remember to limit pruning to 1/2 - 2/3 of the plant's total height. Too much pruning can stunt its growth and harm its overall health.
