About Aeschynanthus radicans 'Curly Q'

Aeschynanthus radicans 'Curly Q' · also called Twisted lipstick plant · flowering

Aeschynanthus 'Curly Q' is a lipstick plant whose waxy dark leaves twist and curl along trailing stems, ending in tubular red flowers that emerge from dark calyx 'tubes'. An epiphytic tropical, it likes bright indirect light, a chunky airy mix and a slight dry-down between waterings. Ideal in hanging baskets, and ASPCA pet-safe.

Mature size: Trailing stems reach 30-60 cm or more; spread depends on training and pruning.

Watch for — Yellowing leaves / root rot: Overwatering or a dense, water-retentive mix suffocates the roots; use an airy epiphytic blend and let the surface dry between waterings.

How to tell aeschynanthus radicans 'curly q' needs repotting

Repotting on a calendar is less reliable than reading the plant. For aeschynanthus radicans 'curly q', watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for aeschynanthus radicans 'curly q') flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to 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 radicans 'curly q'

Only every 2–4 years, when genuinely crowded. Aeschynanthus radicans 'Curly Q' is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Trailing, vining epiphytic evergreen with cascading stems of curled leaves, well suited to hanging baskets..

What size pot to step aeschynanthus radicans 'curly q' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Aeschynanthus radicans 'Curly Q' positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping aeschynanthus radicans 'curly q' into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot aeschynanthus radicans 'curly q'

Early spring, just as new growth restarts, is the ideal window for aeschynanthus radicans 'curly q'. 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 radicans 'curly q'

Confirm it actually needs it. Slide aeschynanthus radicans 'curly q' out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip aeschynanthus radicans 'curly q' out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh light, airy, free-draining epiphytic mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water aeschynanthus radicans 'curly q' again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. 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 radicans 'curly q'

Aeschynanthus radicans 'Curly Q' wants light, airy, free-draining epiphytic mix. Use a chunky blend such as peat or coir with bark, perlite and a little sphagnum, mimicking its life perched on branches and preventing soggy roots. 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 radicans 'curly q' — frequently asked questions

How often should you repot aeschynanthus radicans 'curly q'?

Only every 2–4 years, when genuinely crowded for aeschynanthus radicans 'curly q'. Only repot aeschynanthus radicans 'curly q' every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using light, airy, free-draining epiphytic mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does aeschynanthus radicans 'curly q' need?

When is the best time of year to repot aeschynanthus radicans 'curly q'?

Does aeschynanthus radicans 'curly q' like to be root-bound?

Yes — aeschynanthus radicans 'curly q' genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise aeschynanthus radicans 'curly q' after repotting?

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