Lipstick plant Care (Aeschynanthus radicans)

This plant prefers bright, filtered light that mimics dappled sun under a tree canopy.

• Provide 6–8 hours of bright, indirect light each day, such as near an east or bright north window or under light shade outdoors.
• Allow only gentle early morning sun; protect Lipstick plant from harsh midday or afternoon sun that can scorch leaves or fade color.
• In winter, move it closer to the light source or supplement with grow lights if stems stretch or new leaves emerge small and pale.

Watering should keep the root zone lightly moist but never saturated for healthy growth.

• Water when the top 2–3 cm of soil feel dry, letting water flow freely through drainage holes, then discard excess from saucers or cachepots.
• Use a loose, well-drained mix; persistent wet soil, yellowing leaves, and black, mushy roots indicate overwatering and possible root rot in Aeschynanthus radicans.
• Slightly reduce watering in winter or in lower light; increase checks in warm, bright seasons if leaves wrinkle, curl, or feel thin from drought stress.

Stable, warm conditions support strong growth and flowering.

• Aim for 65–80°F (18–27°C) for active growth, avoiding sudden swings that can cause bud drop or leaf shed.
• Protect the plant from temperatures below 55°F (13°C); it is not frost tolerant and should be sheltered before any risk of freezing.
• In hot weather above 85°F (29°C), keep it shaded from intense sun, ensure good air movement, and monitor soil moisture so roots do not overheat or dry out completely.

This species prefers moderately high humidity and reacts quickly to very dry air.

• Aim for 50–70% humidity to keep leaves firm and flowering regular in Lipstick plant.
• In prolonged dry air, leaf tips brown, buds drop before opening, and foliage may curl slightly inward.
• Increase humidity with a nearby humidifier, grouped plants, or a pebble tray, but keep leaves dry to reduce fungal risk.

This species performs best in a loose, airy, organic-rich potting mix that drains rapidly.

• Use a base of all-purpose houseplant or African violet mix, then add 30–40% perlite plus fine orchid bark for structure and air pockets.
• Target slightly acidic to neutral pH around 6.0–7.0, which supports nutrient uptake and root health in Aeschynanthus radicans.
• Ensure the mix feels springy rather than dense when squeezed; it should fall apart easily instead of forming a tight ball.
• Avoid heavy garden soil, pure peat, or any mix that stays wet for days, as this encourages root rot and weak growth.

This trailing species is very suitable for container growing, including hanging baskets and planters.

• Choose a container depth that allows roots to spread laterally, as they form a fibrous mat rather than a deep taproot.
• Use a stable hanging basket or a weighted pot to prevent tipping as stems become long and foliage-heavy on one side.
• Select slightly porous materials like coir or unglazed ceramics when possible to help excess moisture evaporate from the root zone.

Aeschynanthus radicans benefits from light, consistent feeding during active growth for steady foliage and flowering.

• Use a balanced liquid fertilizer (such as 10-10-10 or 20-20-20) diluted to 1/4–1/2 strength for Lipstick plant.
• Feed every 2–4 weeks in spring and summer when growth is active.
• Stop or reduce feeding to once every 6–8 weeks in fall and winter.
• Avoid heavy applications; flush the pot with plain water occasionally to limit salt buildup.

Pruning Aeschynanthus radicans helps maintain a compact, trailing shape and encourages better flowering.

• Carry out main pruning in late winter or early spring before strong new growth starts.
• Remove dead, damaged, or very woody stems back to healthy tissue with clean, sharp scissors or snips.
• Shorten overly long or sparse vines to promote branching and denser foliage.
• Pinch soft tips after flowering to stimulate side shoots and more future blooms.

Repotting keeps the root system healthy and supports flowering in this trailing houseplant.

• Check for roots circling the pot, pushing from drainage holes, or slowed growth as signals to repot.
• Plan to repot every 2–3 years in spring, just as new growth begins.
• Move into a pot only 2–4 cm wider, using a well-drained, airy mix formulated for epiphytes or indoor tropicals.
• Water lightly after repotting, keep in bright but indirect light, and avoid heavy feeding for 2–3 weeks to reduce root stress.

New Aeschynanthus radicans plants are most commonly produced from stem cuttings taken in the growing season.

• Take 7–10 cm non-flowering stem cuttings in late spring or summer, just below a node.
• Remove lower leaves and place cuttings in moist, well-draining mix or perlite, with nodes buried slightly.
• Maintain warmth around 70–80°F, high humidity, and bright, indirect light for reliable rooting.
• Once roots are 2–3 cm long, pot several cuttings together to create a fuller plant.

This species is frost-sensitive and needs mild, stable conditions during winter, especially in temperate climates.

• Keep indoor temperatures around 60–70°F and avoid drafts or sudden cold air near windows.
• If grown outdoors in warm seasons, move containers indoors before temperatures drop below 55°F.
• Provide bright, indirect light and slightly drier soil, allowing the top layer to dry more between waterings.
• Reduce or stop fertilizing in winter to match slower growth and prevent weak, soft tissue.
