About Tweedie's Lipstick Plant

Aeschynanthus tweediei · also called Tweedie's Lipstick Plant, Tweedie's Basket Vine · tropical

Aeschynanthus tweediei is an epiphytic gesneriaceae species from the tropical rainforests of Southeast Asia, closely related to the common lipstick vine and sharing its characteristic tubular flowers and trailing growth habit. It is a specialist collector's species seldom seen outside botanical gardens and specialist nurseries, prized for its compact, neat trailing stems and vibrant blooms. Like all Aeschynanthus, it requires consistently warm temperatures and should never be exposed to temperatures below 15°C. The ASPCA lists Aeschynanthus (lipstick plant) as non-toxic to cats and dogs.

Mature size: Trailing stems to 45–70 cm (18–28 in) in length.

How to tell tweedie's lipstick plant needs repotting

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

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new tweedie's lipstick plant leaves are noticeably smaller than older ones despite good light.

How often to repot tweedie's lipstick plant

Every 12–18 months — sooner if roots show fast. Tweedie's Lipstick Plant's growth habit — trailing epiphytic evergreen with slender, arching stems suited to hanging baskets or mounted displays. — sets the pace.

What size pot to step tweedie's lipstick plant up to

Step up one pot size — about 2–3 cm (an inch) wider. Tweedie's Lipstick Plant grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

The best time of year to repot tweedie's lipstick plant

Early spring, just as new growth restarts, is the ideal window for tweedie's lipstick plant. 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 tweedie's lipstick plant

Time it for spring. Repot tweedie's lipstick plant in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip tweedie's lipstick plant out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh coarse epiphytic mix with excellent drainage in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water tweedie's lipstick plant once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for tweedie's lipstick plant

Tweedie's Lipstick Plant wants coarse epiphytic mix with excellent drainage. Combine fine orchid bark, perlite, and peat-free compost in equal proportions; the roots must never sit in standing water as this rapidly leads to rot in this epiphytic species. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting tweedie's lipstick plant — frequently asked questions

How often should you repot tweedie's lipstick plant?

Every 12–18 months — sooner if roots show fast for tweedie's lipstick plant. Repot tweedie's lipstick plant roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh coarse epiphytic mix with excellent drainage. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does tweedie's lipstick plant need?

When is the best time of year to repot tweedie's lipstick plant?

Can you put tweedie's lipstick plant straight into a much bigger pot?

No. Even a fast-growing tweedie's lipstick plant should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise tweedie's lipstick plant after repotting?

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