Gustavia angustifolia prefers consistently moist soil, but avoid waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during cooler months, but never allow the soil to dry out completely. Ensure good drainage to prevent root rot, especially in containers.

Prune Gustavia angustifolia to maintain shape and remove any dead, damaged, or crossing branches. Light pruning can be done anytime to encourage bushier growth.

Major pruning should be done after flowering to avoid removing flower buds. Use clean, sharp tools for precise cuts.

Propagation of Gustavia angustifolia is primarily done through seeds, which may require stratification or pre-treatment to germinate. Cuttings can also be taken from mature stems, but success rates can vary.

Ensure cuttings are treated with rooting hormone and kept in a humid environment.

Repot Gustavia angustifolia every 2-3 years or when it becomes root-bound. Use a well-draining potting mix amended with organic matter.

Choose a pot that is only slightly larger than the current one to avoid overwatering. Repot in spring before the active growing season begins.
