tetraploid daylily

Tetraploid daylilies (Hemerocallis 'Call To Worship') require 1 to 2 inches (2.5 to 5 cm.) of water a week during the growing season. During hot, dry weather, the plants may need more frequent watering—as often as every other day. Water the plants in the morning to give them a chance to dry. Avoid wetting the leaves as this can lead to fungal problems. In the winter, the plants should receive less water, around 1 inch (2.5 cm) per month. Soaking the root zone with a deep watering is better than light, daily sprinklings, as this encourages deep roots and helps promote drought tolerance.

Tetraploid daylilies (Hemerocallis 'Call To Worship') thrive when grown in full sun. They perform best when receiving at least 6 hours of direct sunlight each day, however, they will tolerate some light shade depending on growing conditions. A location where the plant is in full sun for most of the day is ideal, as the plant can benefit from the extra light and warmth throughout its growing season. In areas with high temperatures, it is advised to provide some light shade during the hottest part of the day to protect the daylily from scorching.

Tetraploid daylilies (Hemerocallis 'Call To Worship') should be pruned in early to mid-spring for best results. Pruning should involve the removal of dead, damaged, or diseased foliage, as well as the thinning of canes or stems to promote air circulation and aid in production of new growth. Stems should be cut back to a pair of healthy buds. Cutting back too much may prevent new growth and reduce blooms. Every 3 or 4 years, it is recommended to cut the daylily back to the basal foliage after flowering has finished. Doing this will rejuvenate the overall plant health and production of blooms.
