About Aeschynanthus pulcher

Aeschynanthus pulcher · also called royal red bugler, beautiful lipstick plant · flowering

Aeschynanthus pulcher, the royal red bugler, is a trailing epiphytic lipstick plant from Southeast Asia with glossy green leaves and bright scarlet tubular flowers set in green-to-purplish calyces. A popular basket plant, it flowers freely given bright indirect light, warmth, moderate humidity and a slightly snug pot, and dislikes cold draughts and soggy roots.

Mature size: Stems trail 45-60 cm or more; spreads about 30-45 cm in a basket.

Watch for — Failure to flower: Low light and an oversized pot suppress blooming. Give bright indirect light, keep the plant slightly pot-bound, and feed with high-potash liquid in summer.

How to tell aeschynanthus pulcher needs repotting

Repotting on a calendar is less reliable than reading the plant. For aeschynanthus pulcher, 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 aeschynanthus pulcher 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 aeschynanthus pulcher

Every 2–3 years; top-dress in the in-between years. Aeschynanthus pulcher's growth habit — trailing, semi-woody epiphytic perennial with cascading stems of waxy leaves and tip clusters of tubular red flowers; a natural choice for hanging baskets. — sets the pace. Aeschynanthus pulcher, the royal red bugler, is a trailing epiphytic lipstick plant from Southeast Asia with glossy green leaves and bright scarlet tubular flowers set in green-to-purplish calyces. A popular basket plant, it flowers freely given bright indirect light, warmth, moderate humidity and a slightly snug pot, and dislikes cold draughts and soggy roots.

What size pot to step aeschynanthus pulcher up to

Move up exactly one pot size. A heavy aeschynanthus pulcher 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 aeschynanthus pulcher

Early spring, just as new growth restarts, is the ideal window for aeschynanthus pulcher. 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 aeschynanthus pulcher

Consider top-dressing first. If aeschynanthus pulcher 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 light, airy, free-draining epiphytic mix 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 aeschynanthus pulcher in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave aeschynanthus pulcher 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 aeschynanthus pulcher

Aeschynanthus pulcher wants light, airy, free-draining epiphytic mix. A well-aerated blend of peat-free potting mix with perlite, orchid bark and a little coir mirrors its epiphytic habit and protects the roots from rot. A snug pot encourages flowering. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting aeschynanthus pulcher — frequently asked questions

How often should you repot aeschynanthus pulcher?

Every 2–3 years; top-dress in the in-between years for aeschynanthus pulcher. Fully repot aeschynanthus pulcher 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 light, airy, free-draining epiphytic mix. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does aeschynanthus pulcher need?

When is the best time of year to repot aeschynanthus pulcher?

Should you top-dress or fully repot aeschynanthus pulcher?

For a big, heavy aeschynanthus pulcher, 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 aeschynanthus pulcher after repotting?

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