Care at a glance

Light

Common Angel's Trumpet needs sun on the leaves, not just bright ambient room light. Requires full sun — at least 6 hours of direct sunlight daily — to flower freely. In hot climates, light afternoon shade prevents wilting but the plant should receive full morning sun. Inadequate light produces lush leafy growth but few or no blooms. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water common angel's trumpet every 2–4 days in summer (soil should be consistently moist but not waterlogged). The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Brugmansia arborea is a thirsty plant, especially in containers and during hot weather. Water deeply and frequently in the growing season. Reduce watering significantly in autumn when growth slows, and water only sparingly during winter dormancy.

Soil and pot

Common Angel's Trumpet grows best in rich, fertile, moisture-retentive but well-draining loam. A nutrient-rich loamy compost amended with perlite (3:1) works well in containers. In the ground, improve heavy clay soils with organic matter. Slightly acidic to neutral pH (6.0–7.0) is ideal. Repot container plants every 1–2 years as roots fill the pot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Common Angel's Trumpet sits happiest at around 50–70% humidity and 7–30°C (45–86°F). Tolerates average garden humidity. In dry climates or when grown indoors, occasional misting of leaves (avoiding flowers) or a nearby water source helps maintain a comfortable moisture level and reduces spider mite pressure. If you keep the room above 7–30°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed common angel's trumpet sparingly. Feed every 1–2 weeks during the growing season with a high-potassium liquid fertiliser (tomato-type) to encourage prolific flowering. In early spring, use a balanced NPK fertiliser to kick-start growth. Stop feeding entirely from mid-autumn through winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on common angel's trumpet in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Wilting despite moist soilUsually indicates root rot from poor drainage or fungal Phytophthora infection — check roots for brown, mushy tissue and improve drainage immediately; in severe cases, take healthy cuttings to restart the plant.
  • Spider mites and whiteflyBoth pests are common, particularly on indoor-overwintered plants; treat with insecticidal soap or neem oil and improve air circulation.
  • Failure to flowerBrugmansia arborea flowers only on mature wood above the first Y-shaped fork — avoid hard pruning of all new growth and ensure the plant receives adequate phosphorus and potassium in its feed.

Propagation

Take 15–25 cm softwood or semi-hardwood tip cuttings in late spring to summer, remove lower leaves, and insert into moist perlite or a 50:50 peat-free compost/perlite mix. Cover loosely and maintain warmth (20–25°C). Rooting takes 3–6 weeks. Can also be grown from seed sown at 20°C, but seedlings are slow. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Common Angel's Trumpet is toxic to pets. SEVERELY TOXIC. All parts of Brugmansia arborea — leaves, stems, flowers, seeds, and roots — contain high concentrations of tropane alkaloids including scopolamine, atropine, and hyoscyamine. These are toxic to dogs, cats, horses, and humans. Ingestion causes tachycardia, dilated pupils, dry mouth, hallucinations, seizures, and can be fatal. ASPCA lists Brugmansia species as toxic to dogs, cats, and horses. Keep completely out of reach; wear gloves when handling. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Common Angel's Trumpet care — frequently asked questions

What is the common name for Brugmansia arborea?

Brugmansia arborea is most commonly called Common Angel's Trumpet, but it is also known as Common Angel's Trumpet, Maikoa, Tree Datura. The names refer to the same species, so care instructions for Common Angel's Trumpet apply identically to anything sold as Maikoa.

How much light does common angel's trumpet need?

Common Angel's Trumpet grows best in direct sun (at least 4-6 hours). Requires full sun — at least 6 hours of direct sunlight daily — to flower freely. In hot climates, light afternoon shade prevents wilting but the plant should receive full morning sun. Inadequate light produces lush leafy growth but few or no blooms.

How often should I water common angel's trumpet?

Water common angel's trumpet every 2–4 days in summer (soil should be consistently moist but not waterlogged). Brugmansia arborea is a thirsty plant, especially in containers and during hot weather. Water deeply and frequently in the growing season. Reduce watering significantly in autumn when growth slows, and water only sparingly during winter dormancy. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is common angel's trumpet toxic to cats and dogs?

Common Angel's Trumpet is toxic to pets. SEVERELY TOXIC. All parts of Brugmansia arborea — leaves, stems, flowers, seeds, and roots — contain high concentrations of tropane alkaloids including scopolamine, atropine, and hyoscyamine.

What USDA hardiness zone does common angel's trumpet grow in?

Common Angel's Trumpet is rated for USDA zone 9–11 and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
