Chinese Trumpet-Creeper requires regular watering during its establishment phase, typically the first year. Once mature, it becomes quite drought-tolerant, but consistent moisture during dry spells will promote better flowering. Avoid waterlogging, as this can lead to root rot. Water deeply rather than frequently to encourage strong root development.

Pruning is essential to manage its vigorous growth and promote flowering. The best time to prune is in late winter or early spring before new growth emerges. Remove dead, damaged, or weak stems. Cut back side shoots to two or three buds from the main framework to encourage more blooms. Hard pruning can rejuvenate older plants.

Chinese Trumpet-Creeper can be propagated through several methods. Semi-hardwood cuttings taken in summer are a common approach, rooting easily in a moist, well-drained medium with rooting hormone. Layering is another effective method, where a stem is buried in the soil until it roots. Seeds can also be sown, but germination can be erratic.

While typically grown in the ground, if grown in a large container, repotting may be necessary every 2-3 years to refresh the soil and provide more space for root growth. Choose a container only slightly larger than the previous one. This is best done in late winter or early spring before active growth resumes.
