Keep the soil consistently moist but not waterlogged, especially during active growth. Reduce watering in winter to prevent root rot.

Brugmansia versicolor thrives with regular watering, but ensure good drainage to avoid standing water.

Prune to maintain desired shape and size, typically in late winter or early spring before new growth begins. Remove dead or crossing branches. Pinching back new shoots can encourage bushier growth and more flowers.

Remove spent flowers to prolong blooming.

Easily propagated from semi-hardwood cuttings taken in summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep moist and warm, ideally with bottom heat, to encourage root development.

Seed propagation is also possible but slower.

Repot young plants annually and mature plants every 2-3 years into a slightly larger container. Use a rich, well-draining potting mix. Repot in spring before the onset of active growth.

Ensure the new pot has adequate drainage holes.
