How Do I Grow Hemerocallis (Daylilies)?

Growing Hemerocallis, commonly known as Daylilies, is easy and rewarding. These hardy perennials are adaptable, long-lived and suitable for a wide range of garden conditions. If you want to grow Hemerocallis successfully, providing the right soil, sunlight and care will help produce healthy plants and abundant flowers.

Choosing the Best Location

Hemerocallis thrive in full sun and will flower most prolifically when they receive at least six hours of sunlight each day. They will tolerate partial shade, although flowering may be reduced. Daylilies prefer fertile, well-drained soil but can adapt to a wide variety of growing conditions.

Planting Hemerocallis

The best time to plant Hemerocallis is during spring or autumn, although container-grown plants can be planted throughout the growing season. Dig a hole larger than the root system and improve the soil with compost or well-rotted organic matter before planting. Position the crown so it sits just at soil level and firm gently into place.

Watering and Feeding

Regular watering is important while plants are becoming established. Once settled, Hemerocallis are relatively drought tolerant. Avoid overfeeding, particularly with high-nitrogen fertilisers, as this can encourage excessive leaf growth at the expense of flowers. A balanced fertiliser applied in spring is usually sufficient.

Mulching and Maintenance

Applying a mulch of compost or well-rotted organic matter helps retain moisture, suppress weeds and improve soil structure. Remove spent flower stems after blooming and tidy old foliage in autumn or early spring to keep plants looking their best.

Dividing Daylilies

Established clumps can be divided every few years to maintain vigour and increase your stock of plants. Lift the clump in spring or autumn, separate the fans and replant them immediately into prepared soil.
