Madagascar jasmine Care (Stephanotis floribunda)

This tropical climber needs bright light to flower well without scorching its leaves.

• Provide 4–6 hours of bright, indirect light daily; gentle morning sun with afternoon shade suits Madagascar jasmine best.
• Outdoors, place where it receives filtered light through a canopy or light dappled shade, especially in hot summer climates.
• Too little light causes weak, stretched growth and few blooms, while harsh midday or afternoon sun can bleach or burn leaves, especially behind glass.

Stephanotis floribunda prefers evenly moist but never soggy soil, with slight drying between waterings.

• Water when the top 2–4 cm of soil feel dry, using enough water to moisten the full root zone, then let excess drain away fully.
• In warm, active growth, expect more frequent watering; in cooler seasons or reduced light, extend intervals as drying slows.
• Watch for yellowing, soft leaves or a sour soil smell as signs of overwatering, and for dull, limp, or curling leaves as signs of underwatering.

This species thrives in warm, stable temperatures with protection from cold drafts and frost.

• Aim for 65–80°F (18–27°C) during active growth; short peaks to 85°F (29°C) are tolerated if humidity and watering are adequate.
• Growth slows below about 60°F (16°C); protect the plant if temperatures approach 50°F (10°C), where cold stress becomes likely.
• Stephanotis floribunda is not frost hardy; even light frost can damage foliage, while prolonged heat above 90°F (32°C) may cause bud drop and leaf scorch.

This vine benefits from moderately high humidity to keep foliage and buds healthy.

• Aim for 50–70% humidity, as very dry central-heated rooms often cause bud drop and leaf edge browning in Madagascar jasmine.
• If air falls below ~40%, monitor for curled leaves, crisp tips, and flowers that fail to open or fall prematurely.
• Increase humidity with a nearby humidifier, grouping plants, or a pebble tray under the pot, but avoid misting heavy buds to limit fungal spotting.

Stephanotis floribunda grows best in a loose, airy, sharply draining mix that still holds steady moisture.

• Use a peat- or coco-based potting mix amended with 20–30% perlite and 10–20% fine bark to keep structure open and well aerated.
• Aim for slightly acidic to neutral pH around 6.0–7.0, which supports nutrient uptake and reduces the risk of micronutrient lockout.
• Ensure water drains freely in under 30 seconds; if it pools on the surface or the pot feels heavy for days, lighten the mix with more perlite or bark.
• Avoid heavy garden soil, pure compost, or mixes dominated by clay, which compact easily, suffocate roots, and promote root rot when kept damp.

This species is well suited to container growing when the pot supports its vining, top-heavy habit.

• Choose a broad, weighty container or place the pot in a heavy cachepot to counterbalance the climbing vine and prevent tipping when trellised.
• Select a pot deep enough for a firm support stake or trellis so root disturbance is minimal when securing vertical growth.
• Use slightly porous materials like unglazed clay only if you can water more often, as they dry the mix faster than plastic or glazed containers.

This tropical vine benefits from moderate, targeted feeding to support foliage and flower production.

• Use a balanced liquid fertilizer (around 10-10-10 or 20-20-20) diluted to 1/2 strength for Madagascar jasmine in active growth.
• Apply every 2–4 weeks during spring and summer, always on moist soil to prevent root burn.
• Switch to a balanced slow-release or organic compost-based feed if you prefer fewer applications.
• Reduce feeding to once every 6–8 weeks, or stop entirely, during fall and winter dormancy.

Thoughtful pruning helps keep Stephanotis floribunda compact, tidy, and flowering well on its support.

• Carry out main pruning in late winter or very early spring before active growth resumes.
• Remove dead, damaged, or tangling stems first, then thin crowded shoots to improve light and airflow.
• Shorten overly long vines to maintain the desired shape and encourage side shoots with more flowering points.
• Use clean, sharp pruning shears and make cuts just above a leaf node to reduce dieback.

Container-grown plants appreciate careful, infrequent repotting to avoid disturbing their sensitive roots.

• Repot every 2–3 years in spring when roots circle the pot, emerge from drainage holes, or growth slows noticeably.
• Choose a container only 2–5 cm wider than the old one and use a free-draining, rich potting mix.
• Water the plant well the day before, then gently loosen and lift the root ball to limit tearing.
• After repotting, water thoroughly, keep in bright indirect light, and avoid heavy feeding for 2–3 weeks to reduce stress.

New plants are most reliably produced from semi-ripe stem cuttings rather than seed.

• Take 8–10 cm semi-ripe cuttings in late spring or early summer from healthy, non-flowering shoots.
• Remove lower leaves, dip the cut end in rooting hormone, and insert into a sterile, free-draining mix.
• Maintain high humidity, bright indirect light, and a stable temperature around 70–75°F for rooting.
• Keep the medium slightly moist, then pot on gently once strong new roots and growth appear.

This vine is frost-sensitive and needs sheltered winter conditions in most temperate climates.

• Keep outdoor containers in a frost-free spot or move indoors before temperatures drop below 50°F.
• Grow indoors in bright, cool conditions around 60–68°F, away from cold drafts and heating vents.
• Water less in winter, allowing the top layer of soil to dry slightly while preventing full dryness.
