How to Divide up Hybrid Daylilies

Overview

Daylilies are a small to medium plant with grass-like leaves and large, palm-sized flowers which appear on the ends of stalks during the summer months. A single plant can produce dozens of flowers a season, each of which bloom for only one day. Daylilies grow into multiple plants as the years go by. Every five to six years you'll need to divide hybrid daylilies to give each new plant room to grow and encourage flowering to continue.

Step 1

Dig up the daylily area in late summer, after blooming has finished, starting 8 inches away from the base of the plant. Work the shovel toward and under the roots. Lift the entire root, intact, from the ground.

Step 2

Rinse the root cluster with clean, cool water to wash away dirt so you can see the roots better.

Step 3

Look over the root cluster to notice individual sections of plants with at least three leaves. Pull outlying plants away from the main cluster with your hands, working to loosen the roots to separate the plant, rather than ripping the roots apart.

Step 4

Use a spading fork or cultivator, if needed, to pry the tangled, thick roots toward the center apart without piercing the roots. Depending on the plant, this may be relatively easy, while older plantings with larger roots may be more difficult and require more force.

Step 5

Plant each of the individual plants 1 foot apart into soil similar to where it came from. Do this as soon as you've divided them. Keep the plants well watered for the first three to four weeks as the roots adjust and grow.

Tips and Warnings

  • Try not to cut any of the roots, if possible, to avoid introducing disease to your plant.
