Early October is a perfect time to divide and replant perennials. It’s still warm enough for the plants to become established before the first hard frost.

Gardeners usually have three main reasons to divide perennials:

  • To reduce overcrowding.
  • Performance and flowering has declined.
  • Dieback in the middle has occurred.

Divide day lilies in fallMany varieties respond well to fall divisions. They include:

  • Asiatic lilies.
  • Bearded iris.
  • Chrysanthemum.
  • Daylilies.
  • Hosta.
  • Jacob’s ladder.
  • Peonies.
  • Tall phlox.
  • Siberian iris.

Tonkadale Greenhouse recommends these steps for dividing plants:

  • Dig up the entire root ball.
  • Cut or tease roots apart.
  • Discard woody old centers and soft or rotted plant material.
  • Create divisions with two or three new shoots and a solid segment of healthy roots.
  • Plant division at the same depth of the original plant.
  • Water new divisions in well and continue to water heavily for several weeks while new roots emerge.
