How to Grow Brugmansia
Brugmansia suaveolens
Frost-tender shrub with spectacular pendant trumpet flowers. Grow in a large pot, move outdoors in summer, overwinter frost-free indoors. Feed heavily and water generously during the growing season. All parts are highly toxic.
Yearly Lifecycle
Care Essentials
Heavy feeder. Apply a high-potash liquid feed weekly from late spring through autumn while actively growing and flowering. Reduce to monthly in winter under glass.
Watch For
- Whitefly
- Red spider mite
- Aphids
- Tobacco mosaic virus
- Root rot from overwatering

☀️ Light
Full sun to light dappled shade; sheltered from strong wind.
Brugmansia performs best in a warm, sunny, sheltered position — at least 6 hours of direct sun per day encourages the most flowers. Avoid exposed windy sites which shred the large leaves and reduce flowering.
💧 Watering
Water deeply every 1–2 days in summer; reduce significantly in winter.
These plants have enormous leaves and transpire heavily in warm weather. Water until it flows freely from the drainage holes, then allow the top few centimetres to dry before watering again. In winter under glass, keep the compost barely moist but never bone dry.
🌱 Fertilizing
High-potash liquid feed weekly from late spring to autumn.
Apply tomato feed or a dedicated high-potash fertiliser at the recommended strength once a week from May to October while the plant is actively growing and flowering. Without generous feeding, flowering is sparse. Reduce to monthly in winter.
✂️ Pruning
Prune hard in early spring; tidy lightly after each flush of flowers.
In late February or March, before new growth begins, cut back all shoots to leave a framework of main branches. This keeps the plant to a manageable size and stimulates vigorous new flowering growth. Always wear gloves — all parts are toxic.
❄️ Overwintering
Move indoors before the first frost; keep frost-free at 5–10°C.
Before overnight temperatures drop below 5°C (usually October in the UK), move the plant into a frost-free conservatory, heated greenhouse, or cool bright room. Reduce watering and stop feeding. Some leaf drop is normal. Move back outdoors after the last frost in spring.
Growing Tips
Always wear gloves
Every part of brugmansia — leaves, stems, flowers, seeds and roots — is highly toxic. Wear gloves whenever handling the plant and wash your hands thoroughly afterwards. Keep children and pets well away.
Feed generously for flowering
Brugmansia is an extreme heavy feeder. Without weekly high-potash liquid feeds from late spring through autumn it will produce foliage at the expense of flowers. Tomato feed is an economical and effective choice.
Move outdoors after the last frost
Once overnight temperatures stay reliably above 5°C (usually late May to early June in the UK), move the plant to a sheltered sunny spot outside. The combination of warmth, sunlight, and fresh air dramatically boosts flowering.
Hard pruning rejuvenates old plants
If the plant becomes leggy or too large, cut it back hard in early spring before new growth begins. It will reshoot vigorously and often flowers more prolifically after a hard prune.
Pests & Diseases
Pest Whitefly
Identification: Clouds of tiny white-winged insects fly up when foliage is disturbed; sticky honeydew and sooty mould develop on leaves below.
- Hang yellow sticky traps near the plant to monitor and reduce adult populations.
- Spray thoroughly with insecticidal soap or diluted neem oil, covering leaf undersides where eggs and nymphs cluster.
- Apply a pyrethrin-based contact spray in the evening to avoid harming beneficial insects. Repeat every 5–7 days for three applications.
Pest Red Spider Mite
Identification: Fine pale stippling on upper leaf surfaces; delicate webbing on undersides; leaves eventually turn bronze and drop.
- Increase humidity by misting regularly — mites thrive in hot, dry conditions.
- Spray with diluted neem oil or insecticidal soap, concentrating on leaf undersides.
- Use a miticide containing bifenazate or abamectin; rotate products to prevent resistance.
Pest Aphids
Identification: Clusters of small soft-bodied insects (green, black, or grey) on new shoot tips and flower buds; sticky deposits and distorted growth.
- Blast off with a strong jet of water from a hose.
- Encourage natural predators such as ladybirds and lacewings; spray with soft soap solution if populations explode.
- Apply a systemic insecticide containing thiacloprid or acetamiprid as a soil drench for long-lasting control.
Disease Tobacco Mosaic Virus Tobacco mosaic virus (TMV)
Symptoms: Irregular yellow-green mosaic mottling on leaves; leaf distortion, stunting, and reduced flowering; symptoms may vary with temperature.
Treatment: There is no cure. Remove and destroy affected plants immediately to prevent spread. Disinfect tools with a 10 % bleach solution or methylated spirits between cuts.
Prevention: Control aphid vectors rigorously. Avoid handling tobacco products before touching the plant (TMV can persist on hands). Never compost infected material.
Disease Root Rot Phytophthora spp. / Pythium spp.
Symptoms: Sudden wilting despite moist soil; yellowing lower leaves; soft, dark, foul-smelling roots when the plant is removed from its pot.
Treatment: Remove all rotten roots, dust with sulphur or cinnamon powder, repot in fresh free-draining compost and a clean pot. Reduce watering frequency.
Prevention: Ensure the pot has adequate drainage holes. Never allow the plant to sit in a saucer of standing water. Water deeply but allow the top of the compost to dry slightly between waterings.
