Water Oxypetalum coeruleum regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogged roots, especially during its active growing season.

Reduce watering in winter to mimic its dormant period, preventing root rot.

Prune Oxypetalum coeruleum in late winter or early spring to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing stems.

Light pinching of new growth can promote a more compact and floriferous plant.

Propagate Oxypetalum coeruleum from seed sown in spring or from semi-hardwood cuttings taken in summer. Seeds require warmth and consistent moisture to germinate.

Cuttings should be rooted in a well-draining medium in a warm environment.

Repot Oxypetalum coeruleum every 2-3 years, or when root-bound, preferably in spring before new growth begins. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
