🌱 How to Care for European feather grass to Prevent Aphids?

💧 How to Water

Keep the soil evenly moist during the first few weeks after planting to allow the root system to establish. Afterward, European feather grass is exceptionally drought-tolerant: water only during long, rainless periods, and always allow the top layer of soil to dry out between waterings, as constant moisture causes root and crown rot.

☀️ Lighting

Choose a fully sunny location exposed to direct light for at least 6-8 hours a day—it can survive in partial shade, but will only reward you with sparse blooms and looser, less decorative panicles.

🪴 Ideal Soil

It prefers loose-textured, sandy, gravelly, or calcareous soil with excellent drainage; heavy, clayey, water-retentive soil easily leads to crown rot in winter. Lean, nutrient-poor media are also suitable, and in fact, more ideal than overly rich garden soil.
