angel's-trumpet Care (Brugmansia × candida)

Brugmansia × candida grows best in bright, direct light with some protection from intense midday sun.

• Provide 4–6 hours of direct morning sun plus bright, filtered light in early afternoon for strong flowering and compact growth.
• Tolerates light afternoon shade, especially in hot climates; deep shade leads to weak, leggy stems and few blooms on angel's-trumpet.
• In summer, protect from harsh sun between 1–4 p.m. to reduce leaf scorch; in cooler months, choose the sunniest possible position to maintain flowering.

Brugmansia × candida needs consistently moist but not waterlogged soil to support its large leaves and heavy flowering.

• Water when the top 3–5 cm of soil feels dry, soaking the root zone thoroughly so moisture reaches deeper layers.
• Use deep, well-drained soil; yellowing, soft leaves and a sour smell suggest overwatering, while drooping, dry leaves and brittle stems indicate underwatering.
• Increase watering frequency during hot, windy periods and peak flowering, then reduce gradually in cooler seasons while still preventing the root ball from fully drying out.

This species prefers mild, frost-free conditions with warm days and cooler nights.

• Aim for daytime temperatures of 65–80°F (18–27°C) for vigorous growth and flowering, with slightly cooler nights around 55–65°F (13–18°C).
• Brugmansia × candida is very frost-sensitive; sustained drops below 32°F (0°C) can kill top growth, and roots may die if soil freezes solid.
• Tolerates short heat spikes to about 90°F (32°C) if soil moisture is maintained, but prolonged extreme heat can reduce flowering and cause leaf scorch.

This species prefers moderately humid air but tolerates typical home conditions if soil moisture is kept steady.

• Aim for 40–60% humidity, which suits both outdoor and indoor placements in most regions.
• Dry air can cause curled, browning leaf edges and flower bud drop on angel's-trumpet.
• Increase humidity locally with grouped plants, a nearby water tray, or by positioning above but not inside a pebble tray with water.

Brugmansia × candida performs best in deep, moisture-retentive yet free-draining soil that supports fast seasonal growth.

• Use a loamy, organic-rich mix, for example 50% peat or coco coir, 30% compost, and 20% perlite or coarse sand.
• Ensure fast drainage so water runs through within seconds while the mix still feels slightly spongy, not compacted.
• Keep pH slightly acidic to neutral, around 6.0–7.0, avoiding strongly alkaline or salty soils that reduce nutrient uptake.
• Improve aeration by incorporating chunky bark or perlite and avoid heavy, unamended clay or dense garden soil in containers.

This species adapts well to container growing when the pot supports its vigorous, top-heavy growth.

• Select a large, deep container to allow substantial root volume, which helps sustain dense foliage and repeated flowering.
• Choose a wide, heavy pot or add weight at the base to prevent tipping in wind as the canopy becomes top-heavy.
• Use a container material that matches climate, such as thicker, less porous pots in hot areas to reduce rapid moisture loss.

Brugmansia × candida is a heavy feeder and benefits from consistent nutrition during warm, active growth.

• Use a balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) at 1/2 strength every 7–14 days in spring and summer for lush growth and blooms.
• Supplement container plants with slow-release granules or a thin layer of well-rotted compost at the soil surface at the start of the season.
• Water before applying soluble feeds to prevent root burn and ensure even nutrient uptake in angel's-trumpet.
• From late fall through winter dormancy, stop or reduce feeding to once every 4–6 weeks at 1/4 strength, if the plant retains foliage.

Pruning Brugmansia × candida supports strong branching, manageable size, and better flowering.

• Carry out main structural pruning in late winter or very early spring before vigorous new growth begins.
• Remove dead, damaged, crossing, or inward-growing branches first, then thin crowded stems to open the canopy.
• Use sharp, clean bypass pruners or loppers, cutting just above outward-facing buds or branch junctions.
• Avoid cutting off all Y-shaped branches, since flower buds form on the horizontal growth that develops above these forks.

This fast-growing shrub often outgrows containers and benefits from timely repotting or transplanting.

• Check for roots circling the pot, emerging from drainage holes, or for slowed growth and quick drying soil as cues to move up.
• Plan repotting or transplanting for spring, just as consistent warm weather returns and new growth starts.
• Shift to a container 5–8 cm wider, using a rich, free-draining mix; set garden plants at the same soil depth as before.
• Water thoroughly after moving, provide shade and shelter from strong wind for 5–7 days, and keep soil evenly moist to limit transplant shock.

Brugmansia × candida is commonly propagated from cuttings to maintain desired flower traits.

• Take 10–20 cm softwood or semi-ripe stem cuttings in late spring to summer, choosing non-flowering shoots with several nodes.
• Remove lower leaves, optionally dip the base in rooting hormone, and place cuttings in a sterile, free-draining mix such as perlite and peat or coco coir.
• Maintain bright, indirect light, high humidity, and soil temperatures around 70–75°F to encourage rooting.
• Seeds can be sown in warm conditions but often produce variable offspring, so are mainly used for breeding rather than exact clones.

This plant is frost tender and needs specific winter care in most temperate climates.

• In regions below USDA zone 9, grow Brugmansia × candida in containers or treat as a plant that must be lifted or heavily protected.
• Before first frost, move potted plants indoors to a bright, cool room or an unheated but frost-free garage or basement.
• Outdoors in mild climates, apply a 5–10 cm mulch layer over the root zone and shelter stems from freezing winds.
