Planting & Care for Blue Fescue Grass

Preparation
  • Blue Fescue is a cool season, with clump-forming grass. It's a hardy, low-tufted cool season grass with a powdery, silver-blue coloration.
  • Thin blades are gracefully arched, but only attain a height of 4-8" or so and 6-10" when blooming.
  • Remember to trim back foliage late in March or early April each year to keep them looking well-cut.
  • Be sure to plant in full sun to partial shade in well-drained soils.
  • Drought tolerant once established.
  • Thrives in hardiness zone 4.
Opening Plant Material
  • Containers: Completely saturate all container plants by putting them in a larger water container until bubbling stops. Remove the plant, then dig a hole no deeper than the depth of the container, ensuring it’s wider on the sides by an additional 6” or more.
Planting Containers
  • Dig a hole no deeper than the depth of the container and 6" or wider on the sides.
    Slide the plant from the pot by tapping on the bottom of the pot.
  • With a shovel or knife, trim the bottom 2" off the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
    Place the root ball in the hole.
  • Adjust the plant height so the root crown is slightly higher than the ground.
    Notice where the base of the trunk flares out from the tree. This is called the root flare. This root flare should show when the tree is planted. Add soil under the ball so the root flare is exposed if necessary.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer.
  • Backfill the hole with soil, ensuring the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.
  • See our link below, “Planting & Handling Help,” for a downloadable planting guide with illustrations.
Pruning - After Planting
  • Containers: Although it’s not essential after planting, light pruning can help shape a Blue Fescue ornamental grass. Doing so removes any broken branches from shipping or thins out a heavily branched plant to assist in the transplanting process and the appearance of your new planting.
Pruning - Through-out the Season
 Watering - After Planting
  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the six-week establishment period, water once per week unless rain occurs.
  • Remember to check soil moisture by sticking your finger into the soil around 3”.
Watering - Through-out the Season
  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it’s dry, give it a good soak with the hose end (no nozzle), watering the soil only, not the leaves.
  • Same as after planting, stick your finger into the soil around 3” to check soil moisture.
