Water Grona triflora thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during the dormant winter months, allowing the soil to dry out more between waterings to prevent waterlogged conditions.

Prune Grona triflora in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain a healthy structure and encourage bushier growth.

Light pruning can also be done after flowering to shape the plant.

Propagate Grona triflora by softwood cuttings taken in late spring or early summer. Dip the cut ends in rooting hormone and plant them in a well-draining potting mix.

Keep the cuttings moist and provide bottom heat for best results.

Repot Grona triflora every 2-3 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix and repot in spring before active growth commences to minimize transplant shock.
