Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during the first few years and dry spells, to maintain consistent soil moisture. Reduce watering in winter.
Prune immediately after flowering to shape the plant and remove any dead or crossing branches. Avoid heavy pruning in late summer or fall as it can remove next year's flower buds.
Easily propagated from semi-hardwood cuttings taken in mid-summer. Layering is also effective. Seed propagation is possible but slower and may not produce true-to-type plants.
Not typically repotted as it is a large climbing vine. For container-grown specimens, repot every 2-3 years into a larger container with fresh potting mix.
