Elijah Blue Fescue (Festuca glauca ‘Elijah Blue’) is a popular ornamental grass known for its striking silvery-blue foliage and compact growth habit. This guide provides detailed instructions on how to plant, grow, and maintain Elijah Blue Fescue in your landscape.

Planting and Location

Choosing the Right Spot

Elijah Blue Fescue thrives in full sun and well-draining soil. It is well-suited for rock gardens, borders, container gardening, and mass plantings.

Soil Requirements

• Prefers sandy, loamy, or well-draining soil.
• pH range: Slightly acidic to neutral (6.0–7.5).
• Avoid heavy clay soil, as poor drainage can lead to root rot.

Planting Instructions

1. Select a planting location with at least 6 hours of direct sunlight daily.
2. Prepare the soil by loosening it and mixing in organic matter if needed for drainage improvement.
3. Dig a hole twice as wide as the root ball and of equal depth.
4. Place the plant in the hole, ensuring the crown is level with the soil surface.
5. Backfill with soil and gently press down to eliminate air pockets.
6. Water thoroughly after planting.
