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.

Mature size: 3–5 m tall, 2–3 m wide (container specimens typically 1.5–2.5 m)

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.

How to tell angel's trumpet hybrid needs repotting

Repotting on a calendar is less reliable than reading the plant. For angel's trumpet hybrid, watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and angel's trumpet hybrid wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot angel's trumpet hybrid

Every 2–3 years; top-dress in the in-between years. Angel's Trumpet Hybrid's growth habit — fast-growing, large, upright to spreading shrub or small tree — sets the pace. 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.

What size pot to step angel's trumpet hybrid up to

Move up exactly one pot size. A heavy angel's trumpet hybrid dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

The best time of year to repot angel's trumpet hybrid

Early spring, just as new growth restarts, is the ideal window for angel's trumpet hybrid. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting angel's trumpet hybrid

Consider top-dressing first. If angel's trumpet hybrid is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh rich, fertile, well-draining loam or container compost beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave angel's trumpet hybrid in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave angel's trumpet hybrid in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for angel's trumpet hybrid

Angel's Trumpet Hybrid wants rich, fertile, well-draining loam or container compost. A nutrient-rich, peat-free compost blended with perlite (3:1) works well in containers. This hybrid is a vigorous feeder; soil quality directly affects flower quantity and size. pH 6.0–7.0. Repot into a larger container each spring when roots appear through drainage holes. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting angel's trumpet hybrid — frequently asked questions

How often should you repot angel's trumpet hybrid?

Every 2–3 years; top-dress in the in-between years for angel's trumpet hybrid. Fully repot angel's trumpet hybrid only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with rich, fertile, well-draining loam or container compost. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does angel's trumpet hybrid need?

When is the best time of year to repot angel's trumpet hybrid?

Should you top-dress or fully repot angel's trumpet hybrid?

For a big, heavy angel's trumpet hybrid, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise angel's trumpet hybrid after repotting?

Not immediately. Wait about 4 weeks after repotting angel's trumpet hybrid. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
