How to Plant Ornamental Grasses

Plant ornamental grass divisions in spring with the crown at soil level, in full sun. Space them as wide as they'll grow: about 3 feet for fountain grass and 4–6 feet for maiden and zebra grass.

How to Plant Ornamental Grasses
When to plant
Spring is best. Early fall also works, at least 4–6 weeks before the ground freezes
Depth
Crown (neck) at soil level, roots fully covered
Spacing
About 3 feet for fountain grass; 4–6 feet for Miscanthus (maiden, zebra, flame and silver feather grass)
Sun
Full sun, at least 6 hours; some tolerate part shade
Water
Keep well watered through the first growing season; drought tolerant once established
Soil
Most well-drained soils, from sand to clay

Step by step

  1. Choose a sunny spot with room for the grass at its full size; some of ours reach 6–8 feet tall.
  2. Dig a hole large enough to spread the roots out.
  3. Set the plant so its neck (where the stems meet the roots) sits at soil level.
  4. Cover the roots completely so none are left exposed to air, then firm the soil.
  5. Water thoroughly.
  6. Keep the new planting well watered through its whole first growing season. That's the single most helpful thing you can do.

After bloom

Leave the plumes and foliage standing through winter; they look good in snow and protect the crown. In early spring, before new growth starts, cut everything back to 2–4 inches above the ground. Grasses rarely need fertilizer; feed only if growth is pale, weak or floppy. Divide a clump in spring when it gets too big or dies out in the middle.
