Muhly grass (Muhlenbergia species) is a clumping grass with stiff upright foliage. It grows 3 to 5 feet tall and wide. Purplish-pink flowers cover the plant in the fall. Muhly grass is hardy in Zones 7 to 11, and is semi-evergreen in the warmer zones.
Muhly grass is low-maintenance and can be used as an accent plant, in a mixed border or in a mass planting. It grows well in poor soil and can be used for erosion control and in reclamation projects. Plant Muhly grass in the spring or early fall.
Water the Muhly grass plant well with a water hose or watering can and set it in a shady area until you are ready to plant it.
Choose a location in full sun with dry to moderately moist soil. Use a shovel to dig a hole large enough to hold the root ball without squeezing or breaking the roots.
Set the plant in the hole no deeper than it was in the pot. Push the soil into the hole around the root ball with your hands. Tamp down the dirt firmly around the roots and spread the excess soil around the plant. Do not mound the soil up on the plant.
Spread a 3-inch layer of mulch around the grass. Do not mound it up on the plant. If you are planting in the fall, wait until after two or three hard freezes before spreading the mulch.
Water thoroughly with a watering can or water hose.
