How to prune red angel's trumpet

Autumn (when overwintering indoors) or late winter before new growth emerges. Maintain a permanent framework of well-spaced main branches and cut current season's growth back hard to within 2.5 cm (1 in) of older wood. Remove dead, diseased, or crossing branches and any basal suckers entirely.

Annually; remove suckers and dead growth as they appear. Brugmansia sanguinea blooms on new wood, making annual pruning important for heavy flowering. Cut new growth back to within about 2.5 cm of the older woody framework in autumn when moving the plant indoors, or prune in late winter before growth resumes. Always wear gloves — sap is a skin irritant and all parts are toxic.
