Keep the soil consistently moist during the growing season, especially when the plant is in bloom. Water deeply at the base of the plant, avoiding overhead watering which can encourage fungal diseases.

Reduce watering in the fall as the plant begins to go dormant.

Remove spent flower stalks promptly to encourage continuous blooming and prevent seed formation. In late fall or early spring, cut back the old foliage to about 5-10 cm from the ground to maintain a tidy appearance and prevent overwintering pests.

Hemerocallis citrina is easily propagated by division. In early spring or fall, dig up the clumps and carefully separate them into smaller sections, ensuring each division has at least one eye and a good root system.

Replant immediately.

Daylilies generally thrive when slightly crowded and do not require frequent repotting. If necessary, typically every 3-5 years, divide and repot in early spring or fall.

Choose a spot with good drainage and ensure the crown is just at or slightly above soil level.
