Elijah Blue Fescue (Festuca glauca 'Elijah Blue')

🌱

☀️

Sunlight Full sun to partial shade; full sun exposure intensifies the silvery-blue foliage color

💧

Watering Allow the top 2–3 cm of soil to dry completely between waterings to prevent root rot

🌡️

Temperature Hardy to -15°C; tolerates moderate summer heat with proper drainage

🔍

Leaf: Fine, needle-like silvery-blue evergreen foliage forming dense, rounded mounds
Flower: Slender upright stems bearing pale green to tan spikelet inflorescences
Root: Dense fibrous root system that stabilizes clumps and tolerates poor soil

🛠️

Watering

Water deeply when top soil is dry; reduce frequency during rainy periods

Fertilization

Apply a low-nitrogen slow-release fertilizer once in early spring. Over-fertilization can cause foliage to lose its blue color and become green

Banana peel compost tea：Compost banana peels for 4–6 weeks; dilute 1:20 with water for root drench to support foliage vibrancy without overfeeding

Pruning

Gently rake out dead foliage in early spring to refresh clumps
Trim back spent flower stems after blooming to maintain a tidy appearance
Divide overcrowded clumps every 2–3 years in early spring to promote healthy growth
