Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter when the plant is dormant.

Ensure good drainage to prevent waterlogging, which can lead to root rot, especially in potted specimens.

Pruning is typically minimal for Licorice Milkvetch. Remove any dead, damaged, or diseased stems in early spring before new growth begins.

Deadheading spent flowers can encourage further blooming and prevent excessive seed production if desired. Avoid heavy pruning.

Propagate by sowing seeds in early spring or autumn. Seeds may benefit from a period of cold stratification. Alternatively, take cuttings from semi-hardwood in late spring or early summer.

Ensure cuttings are placed in well-draining soil and kept moist.

Repot Astragalus glycyphyllos only when it becomes root-bound, typically every 2-3 years. Use a well-draining potting mix. It's best to repot in spring before active growth commences.

Handle the root ball gently to avoid disturbing the roots excessively, as they can be sensitive.
