Plant guide
マダガスカルジャスミン
Watering rhythm
Every 5–7 days
Madagascar Jasmine is a vining plant native to Madagascar, prized for its delicate white star-shaped flowers and lovely fragrance. It's an excellent choice for beginners—easy to care for and forgiving with most plant parents. It loves warmth and can be sensitive to cold, so keeping it in a consistently warm spot is key to its happiness.
Bright indirect light is your sweet spot. A sunny windowsill works beautifully. Aim for temperatures between 15–25°C (59–77°F), and try to avoid dropping below 10°C (50°F). Humidity around 50–70% keeps it thriving; a light misting every now and then will be much appreciated.
Light and temperature change a plant's metabolism, so the ideal cadence shifts with the seasons.
Spring
Every 4–6 days
Summer
Every 3–5 days
Autumn
Every 5–7 days
Winter
Every 10–14 days
Water thoroughly once the soil surface feels dry to the touch. Pour until water flows from the drainage holes at the bottom—that's your signal you've watered enough. Always empty any standing water from the saucer underneath. The main thing to watch for is overwatering, which can lead to root rot, so let the soil dry out between waterings rather than keeping it constantly moist.
Quick lookup from symptom to likely cause and action.
| Symptom | Likely cause | What to try |
|---|---|---|
| Leaves turning yellow and dropping | Usually triggered by cold stress or root rot—either the plant has been exposed to temperatures below 10°C (50°F), or humidity levels have crept too high. | Move it to a warmer spot (at least 15°C/59°F). During winter, dial back watering so the soil stays on the drier side. |
| Stems becoming soft and mushy | This indicates root rot has set in, typically from overwatering combined with poor air circulation. | Don't hesitate to trim away the rotted sections. Refresh the soil completely with fresh potting mix, move the plant to somewhere with better airflow, and ease up on watering. |
| No flowers appearing, or vines growing slowly | Usually a sign of insufficient light, or the plant has been in a cold environment during its winter rest. | Relocate it to a brighter spot. As spring and summer arrive, make sure it gets plenty of light and warmth (20°C/68°F or higher) to encourage flowering. |
| White powder or visible insects on leaves | Likely scale insects or powdery mildew—both thrive when air circulation is poor. | Gently wipe away the affected areas. Spray the entire plant with an insecticidal or fungicidal spray, and improve airflow around it. Regular check-ins help catch these early. |
| Leaves appearing small and pale in color | Generally points to either inadequate light or nutrient deficiency. Check whether it's been stuck in a dark corner through winter. | Move it somewhere brighter. During the growing season (spring and summer), feed it with diluted liquid fertilizer once or twice a month. Repotting into fresh soil can also give it a boost. |
