How to Care for Angel's Trumpet

Angel's trumpet (Brugmansia spp.) is a large, tender woody shrub or small tree famed for its enormous pendulous, trumpet-shaped flowers that hang like bells and often release fragrance in the evening. It is a heavy feeder and vigorous grower that puts on a spectacular show when given warmth, moisture, and rich soil.

Light

Grow angel's trumpet in full sun to partial shade. In cooler climates give it as much sun as possible for the strongest flowering, while in very hot regions some afternoon shade helps prevent wilting and leaf stress. Indoors or overwintered plants need the brightest spot available or supplemental grow lights to stay compact and healthy.

Water

Brugmansia is thirsty and likes to be kept consistently moist. Its large leaves transpire heavily, so during warm weather and active growth it may need frequent, even daily, watering, especially in containers. Never let it dry out to the point of wilting during the growing season, but ensure the soil drains so roots are not left standing in water. Reduce watering markedly in winter when growth slows or the plant is dormant.

Soil & Potting

Use rich, fertile, well-drained soil with plenty of organic matter to support fast growth and heavy feeding. In containers, choose a large, sturdy pot with good drainage and a quality potting mix enriched with compost. These plants grow quickly and become top-heavy, so a heavy or wide-based pot helps prevent tipping. Consistent moisture retention combined with drainage is the goal.

Humidity & Temperature

Angel's trumpet is a tropical to subtropical plant that thrives in warm, humid conditions and is frost-tender, typically hardy only in USDA zones 9 through 11. It grows best between about 60 and 85 F. In colder regions grow it in a container to move indoors, or overwinter it in a cool, frost-free space. Protect it from cold snaps, as frost damages or kills the top growth.

Feeding

This is one of the heaviest-feeding ornamentals you can grow. During the growing season feed frequently with a balanced or bloom-focused fertilizer; many growers feed weekly with a diluted liquid fertilizer or use a combination of slow-release and regular liquid feeding. Well-fed plants flower far more abundantly. Cut back or stop feeding in late autumn and winter as growth slows.

Propagation

Brugmansia is very easy to propagate from cuttings. Take stem cuttings several inches long in spring or summer, and root them in water or in moist, well-drained mix; hardwood sections often root readily. Keep cuttings warm and humid until roots and new growth appear, then pot them up. This is the standard way to increase named plants and share them.

Repotting / Pruning

Repot container plants annually into fresh, rich mix, moving up a size as the vigorous roots fill the pot. Prune to shape and control size, ideally in late winter or early spring before growth resumes; the plant tolerates hard pruning and regrows strongly. Note that flowers form on the upper, mature branching above the point where the stem forks into a Y, so avoid removing all of that mature wood if you want blooms the same season. Remove dead or weak stems and any suckers at the base.

Common Problems & Pests

Spider mites, whiteflies, aphids, and mealybugs are the most common pests, thriving especially on stressed or indoor-overwintered plants; inspect leaf undersides regularly and treat with insecticidal soap or repeated rinses. Wilting despite moist soil can indicate root problems from poor drainage, while sudden midday wilting in heat often recovers by evening. Yellowing leaves may signal underfeeding in this hungry plant or overwatering in poorly drained soil. Cold damage blackens foliage and stems.

Seasonal Care Tips

In spring, resume watering and heavy feeding, repot, and prune to shape as growth restarts. In summer, water generously, feed regularly, and enjoy peak bloom; watch for pests in heat. In autumn, taper feeding and prepare to protect the plant before frost. In winter, either keep it growing in a bright warm indoor spot with reduced water, or overwinter it dormant in a cool, frost-free place with only occasional light watering.
