🌱 How to Care for Pink Muhly Grass to Prevent Spider Mites?

💧 How to Water

Water newly planted pink muhly grass weekly for the first growing season to help it establish. Once established (typically after one full season), it becomes highly drought tolerant and needs only deep, infrequent watering — roughly every 10–14 days during dry spells, or none at all where rainfall is regular. Never let the plant sit in waterlogged soil; excellent drainage is essential. Reduce watering significantly in fall and winter.

☀️ Lighting

Pink muhly grass demands full sun — a minimum of 6 to 8 hours of direct sunlight per day — to produce its iconic pink plumes. In partial shade, the plant will grow but flowering is significantly reduced and the foliage tends to become leggy and lax. Site it in the sunniest spot in the garden for the best floral display each autumn.

🪴 Ideal Soil

Plant in sandy, rocky, or well-draining loamy soil with a pH between 5.5 and 8.0. Pink muhly grass actually performs better in lean, low-fertility soils — overly rich or heavily amended soils encourage excessive foliage at the expense of flowers. Avoid clay or poorly drained soils entirely, as they promote root rot. It is remarkably salt-tolerant, making it excellent for coastal gardens.
