Water Alkekengi regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during hot weather.

Reduce watering in the fall and winter when the plant's growth slows down.

Prune Alkekengi in late winter or early spring before new growth emerges. Remove any dead, damaged, or weak stems. You can also prune to control the plant's size and shape, or to encourage bushier growth.

Deadheading spent flowers can prevent self-seeding if undesired.

Alkekengi can be easily propagated from seeds sown in spring or by division of established clumps. Seeds can be sown directly outdoors after the last frost or started indoors a few weeks prior.

Divisions are best performed in early spring as new growth appears.

Alkekengi is a vigorous grower and may benefit from repotting every 2-3 years, preferably in early spring. Choose a pot that is only slightly larger than the current one.

Ensure the new pot has adequate drainage holes to prevent root rot.
