Water moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as Erythroxylum havanense is susceptible to root rot.

Reduce watering during cooler months, allowing the soil to dry out slightly more between waterings to mimic its natural habitat's drier periods.

Prune to maintain desired shape and size, and to remove any dead or crossing branches. Light pruning can be done anytime.

For more significant shaping, prune in late winter or early spring before the main growth flush begins. This encourages bushier growth.

Propagate from semi-hardwood cuttings taken in late spring or early summer. Dip cuttings in rooting hormone and plant in a well-draining medium.

Maintain high humidity and consistent warmth for successful rooting, which typically takes several weeks to a few months.

Repot young plants annually or every two years in spring. Mature plants can be repotted less frequently, every 3-4 years. Use a well-draining potting mix.

Choose a pot only slightly larger than the current one to avoid waterlogged soil and encourage healthy root development.
