Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry periods, to maintain consistent soil moisture. Avoid waterlogged conditions, which can lead to root rot. Allow the top few centimeters of soil to dry out slightly between waterings.
Reduce watering in cooler months.
Prune in late winter or early spring before new growth begins to control size and shape, and remove any dead or damaged stems. Summer pruning can be done to manage errant growth and encourage denser foliage.
This vigorous vine benefits from regular trimming.
Propagate by semi-hardwood cuttings taken in summer or hardwood cuttings taken in late autumn or winter. Cuttings should be treated with rooting hormone and planted in moist, well-draining soil or a perlite/peat mix.
Keep them in a protected environment until rooted.
Repot young plants annually in spring as they outgrow their containers. Mature plants can be repotted every 2-3 years or when root-bound. Use a good quality, well-draining potting mix.
Ensure the new pot is only slightly larger than the previous one.
