How to Plant Blue Fescue Seed


Blue fescue, scientific name Festuca, is a low-growing perennial ornamental grass that grows in compact mounds of steely to teal blue blades. Growing from 10 to 14 inches tall, blue fescue is the perfect addition to rock gardens or the front and middle rows of flower beds and can add dramatic impact to the landcape when planted in mass. This eye-catching ornamental is hardy in zones 4 through 10, and will produce pale, spiked flowers in the summer months that will self seed if left on the plant.

Step 1

Locate a sunny location that offers some shade during the full heat of the summer months, good drainage and a soil pH of 5.5 to 6.8.

Step 2

Take soil samples to your local garden center or purchase an inexpensive soil testing kit to determine the pH level of the soil at the planting site.

Step 3

Raise pH level by one point by adding 8 oz. of hydrated lime per square yard. pH can be lowered by adding rock sulfur at a rate of 3.6 oz. per square yard.

Step 4

Sow seeds outdoors in early spring after all chance of frost has passed for your location. Place seeds on the soil surface, spaced at least 15 to 18 inches apart, then water lightly to set them in.

Step 5

Water blue fescue seeds 1 inch per week until the plants are established.

Tips and Warnings

  • Keep blue fescue watered regularly during the high heat of summer to prevent blades from turning brown and dying off.
