Planting Instructions (From a 4" Pot into the Ground)

1. Choose the Location

Select a full sun location for best color and compact growth.
Ideal for borders, slopes, coastal plantings, or erosion control.

2. Prepare the Soil

Loosen soil 8–10 inches deep.
Prefers well-drained soil; thrives even in sandy or poor soils.
Avoid overly rich or wet soils.

3. Dig the Hole

Dig a hole twice as wide as the 4" pot and about the same depth.

4. Remove from Pot

Gently remove the plant and loosen any tightly bound roots.

5. Plant

Place the plant so the top of the root ball is level with the soil surface.
Backfill and firm soil gently.

6. Water

Water thoroughly after planting.
Water regularly during establishment, then reduce frequency.

7. Spacing

Space plants 24–36 inches apart to allow for spreading.

Overwintering Lyme Blue Dune Grass

In-Ground (Zones 4–9)

Very cold hardy and requires minimal winter care.
Foliage may persist through winter, adding interest.
Cut back old foliage to a few inches above ground in early spring before new growth emerges.

Maintenance Tips

Divide every few years if clumps become too large or invasive.
Can spread aggressively in ideal conditions—monitor as needed.

Container Plants

Ensure pots have excellent drainage.
Move to a sheltered location in extremely cold climates.
Water lightly during winter to prevent complete drying.
