Pink Muhly Grass has adaptations that make it a great choice for low-water landscapes. However, it needs proper drainage to sustain wet winters. In containers, Pink Muhly Grass takes average moisture but should not stay wet. Over watering, especially during dormancy, can be problematic. Water twice weekly for the first two to three months following planting. After established, this ornamental grass is extremely drought tolerant and rarely needs additional water. The exception is in extreme heat, especially in the first summer.
