Growth Stages
Establishment
4-8 weeksNewly planted divisions develop roots and expand foliage. Little to no flowering may occur the first year.
Keep soil consistently moist for the first 4-6 weeks. Remove any flower buds the first season to encourage root establishment. Apply 2-3 inches of mulch around the base.
Vegetative Growth
Spring to early summerDense clumps of long, narrow, arching green leaves form. The plant rapidly expands and matures.
Water regularly and maintain consistent soil moisture. Apply balanced fertilizer (10-10-10) in spring as growth begins. Remove any dead or damaged foliage.
Flowering (Repeating)
Early June to frost (3-4 months or longer)Bright golden-yellow trumpet-shaped flowers appear on tall, branching scapes. Each flower lasts one day but is continuously replaced by new buds throughout the season.
Deadhead spent flowers daily or every other day to encourage more blooms. Continue regular watering to sustain flowering. Avoid excessive nitrogen fertilizer, which reduces flowering.
Decline & Dormancy
4-6 weeks in fall; dormancy through winterAs temperatures cool in late fall, foliage yellows and dies back. The plant enters dormancy over winter.
Cut back dead foliage to 2-3 inches above ground in late fall or early spring. Reduce watering. Ensure good drainage to prevent crown rot during wet winter months.

Harvest Tips
Daylilies are ornamental flowers; harvest for arrangements by cutting scapes at the base in early morning. Each flower lasts only one day. Cut multiple scapes to extend bouquet longevity. Flowers can also be eaten: harvest unopened buds or just-opened flowers in early morning, chill, and use in salads or stir-fry within a few hours. Remove spent flowers daily to promote continuous blooming throughout the season.
