Care of Muhly Grass

Growing Muhly Grass is easy as it requires little maintenance or upkeep.  You do not have to water once the grass matures. Muhly Grass does look better and flowers abundantly with periodic supplemental irrigation during periods of drought.

Though the grass is semi-evergreen, dead growth should be moved at the base of the clump. Lift the grass blades up and gently pull the loose dead duff of brown dead leaves away from the clump. The grass will look better and this helps to keep it healthy. Note that hard pruning is not recommended for mature muhly grass.

Although usually not necessary, you can also nourish the plants in spring with a diluted by half balanced plant food and water when the soil appears dry in the top couple of inches. That’s all there is to caring for this beautiful grass.
