Watering, pruning, propagation, and repotting details from plant data
Allow the soil to dry out between waterings. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering significantly during winter dormancy. Avoid waterlogging, which can lead to root rot.
Ensure good drainage in the pot.
Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Pruning can also be done to shape the plant and control its size.
This vigorous vine benefits from regular thinning.
Easily propagated from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in moist, well-draining potting mix. Rooting can also be achieved through layering.
Seeds can be sown, but germination can be erratic.
Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one. Repotting is best done in spring.
This plant tolerates being slightly pot-bound.
