Autumn care of daylilies

With your bloom finished, it’s time to prepare your daylilies for the winter to come. 

  • Finish dividing and planting all cultivars. All daylilies should be planted no later than four to six weeks before your typical first hard frost. 
  • Remove all dead and dying foliage and pull old bloom stalks. Leave the healthy foliage for winter protection. 
  • Add mulch in colder climates to protect against winter freeze damage. Mulch in warmer climates if needing to improve soil quality, retain soil moisture, or assist in weed prevention.
