Water Cynanchum acidum thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain completely to prevent root rot.

Reduce watering significantly during the cooler, dormant winter months, allowing the soil to dry out more between waterings to mimic its natural arid environment.

Pruning Cynanchum acidum is minimal and primarily involves removing dead, damaged, or crossing branches. This can be done in late winter or early spring before new growth begins.

If the plant becomes leggy, light shaping can be done after flowering to maintain a desired form.

Propagation of Cynanchum acidum is best achieved through stem cuttings taken during the spring or early summer.

Use a sharp, sterile knife to take cuttings of about 10-15 cm, remove lower leaves, and dip the cut end in rooting hormone. Plant in a well-draining potting mix and keep moist.

Repot Cynanchum acidum every 2-3 years, or when it becomes root-bound. Spring is the ideal time for repotting, just as new growth begins.

Use a slightly larger pot with a well-draining potting mix, such as a cactus or succulent blend, to ensure good aeration and prevent waterlogging.
