How to Multiply Creeping Phlox

Creeping phlox (Phlox subulata) is a slow-growing ground cover that reaches a height of only 6 inches tall. It has deep-green foliage that resembles the needles of an evergreen tree. In mid to late spring, small, dainty-looking blooms form. The blooms are available in a variety of colors, including red, pink, white and purple. Creeping phlox can be multiplied by dividing the roots after the blooms have faded in summer. The new divisions can then be replanted in a sunny or partially shaded area of the garden that has good drainage.

Instructions

    • 1

      Water the creeping phlox plants to be divided one or two days before lifting them from the ground.

    • 2

      Loosen the soil at the new planting site 6 inches deep with a garden fork.

    • 3

      Mix 2 to 3 inches of organic compost with the soil of the new planting site. This adds nutrients and improves drainage.

    • 4

      Dig around the creeping phlox with a sharp spade, beginning about 4 inches from its base.

    • 5

      Work the spade under the clump gradually, until it can be lifted from the ground without pulling.

    • 6

      Shake the clump gently to remove excess soil and dead foliage.

    • 7

      Cut the clump apart with a sharp knife. Discard any woody, unproductive portions.

    • 8

      Replant the divided creeping phlox at its previous depth and water until the soil is moist at root level.
