Watering. Water moderately, allowing the soil to dry out between waterings. Avoid waterlogging to prevent root rot.
Fertilizing. Apply a balanced, slow-release fertilizer in early spring to support healthy growth. Avoid over-fertilizing, which can reduce the plant's blue color and cause excessive leaf growth.
Festuca glauca is a hardy ornamental grass that is easy to care for. It thrives in sunny spots and tolerates dry conditions well. Overwatering can cause root problems, so let the soil dry out between waterings. It requires little maintenance and benefits from trimming old foliage in early spring.

- Moderate
Festuca glauca can produce pollen that may cause mild allergic reactions in sensitive individuals, especially during its flowering season. People with grass pollen allergies should limit exposure during this time. Wearing a mask and keeping windows closed can help reduce pollen inhalation.
Common problems
Overwatering can lead to root rot. Poor air circulation or excessive moisture may cause fungal diseases. It may also become less attractive if not trimmed annually to remove dead leaves.
Uses
Used mainly as an ornamental grass for garden borders, rock gardens, and container planting due to its attractive blue foliage and low maintenance needs.
Notes
Trim back old foliage in early spring to encourage fresh growth and maintain a tidy appearance. Avoid heavy shade as it reduces color vibrancy. Repot container plants every 2-3 years to refresh soil.
