Angel's Trumpet (Angel's tears) care

Light

Most houseplants will scorch where angel's trumpet thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Full sun (6+ hours) for best flowering; tolerates light afternoon shade in very hot climates and in zones 9-11. Indoors or under glass, give the brightest spot available. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

Aim for every 1-3 days in peak summer growth; far less when dormant or overwintering for angel's trumpet, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. A thirsty heavy drinker when in active growth and flower — keep the soil consistently moist but never waterlogged, letting the top partially dry between waterings. Large potted plants in heat may need daily water. Cut back sharply for dormant winter storage, keeping the rootball barely moist.

Soil and pot

Angel's Trumpet grows best in rich, loam-based, free-draining potting mix or humus-rich garden soil. Prefers fertile, organically rich, moisture-retentive but well-drained soil. Use a loam-based (peat-free) compost in containers; ensure drainage holes, as roots rot in standing water. 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

Angel's Trumpet sits happiest at around Moderate to high (50%+) humidity and 15-30C ideal; keep above 7-10C (60-86F ideal; keep above 45-50F). As a tropical plant it appreciates ample humidity. Outdoors in summer this is rarely an issue; indoors over winter, dry air encourages spider mites, so a pebble tray or grouped plants help. If you keep the room above 15 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 angel's trumpet sparingly. Heavy feeder. During active growth feed every 1-2 weeks with a balanced or bloom-boosting (higher potassium/phosphorus) liquid fertiliser; water-soluble feeds at full strength suit established container plants. Stop feeding in autumn before dormancy. 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 angel's trumpet in the Growli community. Each is annotated with the most common cause so you know where to start.

• Spider mites — Common indoors and in dry air, especially over winter. Look for fine webbing, stippling, and yellowing on leaf undersides; treat with insecticidal soap or neem and raise humidity. Breaking the cycle takes 3-4 weeks of repeat treatment.
• Whiteflies — Tiny white moth-like insects clustering under leaves; heavy infestations distort foliage and weaken the plant. They excrete honeydew that leads to sooty mould. Treat with insecticidal soap and sticky traps.
• Aphids and mealybugs — Sap-suckers that cause curling, thickened or crisp leaves and honeydew/mould. Knock back with insecticidal soap, neem, or beneficial insects like ladybirds.
• Failure to flower — Blooms appear only after stems fork into the characteristic Y branching, which needs maturity. Too little sun, too little feed, or over-potting delays flowering — give full sun and regular high-potassium feed.
• Wilting / leaf drop — Usually water stress: these heavy drinkers wilt fast in heat if underwatered, but soggy soil causes root rot. Keep evenly moist with good drainage; some wilting in intense midday heat is normal and recovers by evening.
• Frost damage — Not frost-hardy. Foliage and soft growth are killed below freezing. Move containers in or overwinter dormant in a cool (above 7-10C / 45-50F) frost-free space before the first autumn frost.

Propagation

Easily propagated from stem cuttings: take semi-hardwood tip or stem sections in spring/summer, root in water or moist gritty compost — they root readily and bloom faster than seed-grown plants. Can also be grown from seed, though slower. Wear gloves and wash hands, as sap and all plant parts are poisonous. 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

Angel's Trumpet is toxic to pets. Angel's trumpet is highly toxic to cats, dogs, horses and humans. Brugmansia is not individually listed in the ASPCA database, but the Pet Poison Helpline and toxicology sources classify it toxic: all parts (flowers, leaves and especially seeds) contain tropane alkaloids (atropine, scopolamine, hyoscyamine) that cause dilated pupils, dry mouth, rapid heartbeat, agitation, seizures and can be fatal. Keep it well away from pets and seek immediate veterinary care after any ingestion. 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.
