Angel's Trumpet, known botanically as Brugmansia, is a small tropical tree prized for its large, fragrant, trumpet-shaped flowers. They bloom in a wide range of colors and sizes depending upon the cultivar, of which there are several hundred. Brugmansia does not require regular pruning for bloom performance but will need to be pruned to remove dead plant material. Light pruning can be done throughout the year but significant pruning for size should be conducted in the spring.
Prune back spent flower heads throughout the growing season to keep the tree tidy looking and encourage fresh bloom production. Snip the flowers from their short green stems with clean sharp secateurs and compost or discard the blooms.
Prune your brugmansia as needed during the growing season to remove broken, dying or diseased branches or blooms or any other sign of distressed plant material. Cut away any troublesome areas back to the point of healthy tissues and discard the clippings in the trash. Bypass the compost pile if disease is in any way suspected for the damage to the cuttings.
Prune the brugmansia for height and spread as you desire in keeping with your garden space. Cut each individual branch back to the desired length with secateurs (pruning shears). Don't remove more than one third of the bulk of the tree in any single pruning session.
