Tontelea cylindrocarpa prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.

Reduce watering slightly during cooler months or periods of dormancy. Ensure good drainage to prevent root rot, especially in containers.

Prune Tontelea cylindrocarpa to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to shape the plant and remove spent blooms.

For larger specimens, more significant pruning can be undertaken in late winter or early spring.

Propagate Tontelea cylindrocarpa from semi-hardwood cuttings taken in summer. Select healthy shoots, take cuttings of about 10-15 cm, and dip the cut end in rooting hormone.

Plant the cuttings in a well-draining potting mix, keep them moist, and provide bottom heat if possible. Rooting typically takes several weeks.

Repot Tontelea cylindrocarpa every 2-3 years, or when it becomes root-bound. The best time to repot is in early 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 and encourage healthy root development.
