How to Dig Out the Middle of a Grass Plant

Ornamental grass is a perennial plant that grows from a crown root system that dies out in the middle as it ages. Digging the plant from the ground and dividing the root mass prevents the entire plant from dying. Dividing ornamental grass prevents it from overgrowing, letting you make additional plants for your garden landscape. Cutting out the dead center rejuvenates the ornamental grass for many more years of enjoyment.

Things You'll Need

  • Pruning clipper
  • Shovel
  • Tarp
  • Sharp knife
  • Shovel
  • Gloves

Instructions

    • 1

      Cut the grass blades to a height of about 4 inches with a sharp pruning clipper once it begins to dry in the fall.

    • 2

      Dig around the clump of grass about 6 inches away from the edge of the foliage to remove as much of the root mass as possible. Dig about 12 inches deep and pry the root mass from the ground.

    • 3

      Place the clump of grass and roots on a tarp in a shaded area to keep the root mass moist.

    • 4

      Cut into the grass clump with a sharp knife and remove the dry center foliage and roots. Divide the remaining root mass into 4- to 5-inch clumps for replanting.

    • 5

      Plant the divided clumps immediately into the garden area to prevent the roots from drying out. Set the root mass at the same depth it was growing previously. The top of the root crown should be just below the ground level.
