Crape Jasmine (Carnation of India) care

Light

Bright but filtered. Crape Jasmine burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Performs best in partial shade to filtered bright light. Full afternoon sun in hot climates can scorch the glossy leaves; morning sun or bright dappled light is ideal. Avoid deep shade, which suppresses bloom production significantly. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering crape jasmine: every 5–7 days during growing season; reduce in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water when the top inch of soil dries out. Keep evenly moist during active growth. Avoid waterlogging, which leads to root rot. Once established in ground, moderately drought-tolerant, but container specimens need consistent moisture.

Soil and pot

Crape Jasmine grows best in moist, fertile, well-draining loam or enriched potting mix. Best in slightly acidic to neutral soil (pH 6.0–7.0). Incorporate compost or organic matter to retain some moisture while still draining freely. On alkaline soils, supplement with chelated iron to prevent chlorosis. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Crape Jasmine sits happiest at around 50–70% humidity and 15–32°C (59–90°F). Thrives in moderate to high humidity matching its South Asian origin. Indoors, mist the foliage lightly or use a humidity tray. Avoid placing near heating vents or air conditioners that strip moisture from the air. If you keep the room above 15–32°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed crape jasmine sparingly. Apply a balanced fertiliser (NPK 10-10-10) monthly from spring through summer. After the main flowering flush, switch to a phosphorus-rich formula to promote bud set. Withhold feeding in winter when growth slows. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on crape jasmine in the Growli community. Each is annotated with the most common cause so you know where to start.

• Mealybugs — Cottony white clusters in leaf axils and along stems are a frequent pest. Remove by hand with an alcohol-soaked cotton swab for light infestations; spray with diluted neem oil or insecticidal soap for heavier outbreaks.
• Leaf drop or yellowing — Sudden temperature drops below 10°C or cold draughts cause rapid leaf yellowing and drop. Maintain temperatures above 15°C indoors and avoid cold windowsill draughts in winter.
• Failure to flower — Insufficient light is the primary cause. Move to a brighter position with at least 4 hours of indirect sun. Overfertilising with nitrogen encourages leafy growth at the expense of blooms; balance with phosphorus feeding.

Propagation

Propagate by semi-ripe stem cuttings (10–12 cm) in spring. Wipe the cut end to minimise latex, allow to dry briefly, dip in rooting hormone, and place in a humid propagation chamber at 24–27°C. Rooting takes 4–6 weeks. Air layering is highly effective for larger, woody stems and results in faster establishment. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Crape Jasmine is toxic to pets. Tabernaemontana coronaria contains ibogamine-class alkaloids and a milky toxic latex throughout all plant parts, consistent with the Apocynaceae family. Not individually listed by ASPCA, but the genus is established as toxic — the alkaloid profile causes gastrointestinal distress and central nervous system effects if ingested. Treat as toxic to pets and children; latex can irritate skin and eyes. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
