About Angel's Trumpet Hybrid
Brugmansia × candida · also called Angel's Trumpet Hybrid, White Angel's Trumpet · flowering
Brugmansia × candida is the most widely cultivated Brugmansia hybrid, a cross of B. aurea and B. versicolor, bearing large pendulous white or cream trumpets with a powerful sweet fragrance strongest in the evening. Fast-growing and floriferous, it thrives in sun with rich feeding. All parts are severely toxic to people and pets.
Growth habit: Fast-growing, large, upright to spreading shrub or small tree
Watch for — Failure to come out of dormancy: Plants kept too cold or too dry over winter may be slow to break dormancy — move to a warmer spot in early spring, resume moderate watering, and apply a dilute balanced fertiliser to stimulate growth.
What fertiliser angel's trumpet hybrid actually wants — and why
Angel's Trumpet Hybrid is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for angel's trumpet hybrid: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed angel's trumpet hybrid, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For angel's trumpet hybrid:
Feed every 7–14 days with a balanced liquid fertiliser in spring, switching to high-potassium tomato fertiliser from early summer through to late summer to fuel flowering. This hybrid is a heavy feeder — underfeeding is the most common reason for reduced flowering. Stop feeding entirely in late September. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when angel's trumpet hybrid is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for angel's trumpet hybrid
Half strength is the safe default for angel's trumpet hybrid — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water angel's trumpet hybrid first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the angel's trumpet hybrid watering schedule.
Signs you are over-feeding angel's trumpet hybrid
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for angel's trumpet hybrid:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding angel's trumpet hybrid
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full angel's trumpet hybrid care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of angel's trumpet hybrid with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for angel's trumpet hybrid
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Lower leaves yellow and drop while the soil is correctly watered. Feeding angel's trumpet hybrid year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of angel's trumpet hybrid?
Flush the pot of angel's trumpet hybrid with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
