Watering rhythm
Every 5–7 days
Monstera is a large climbing plant native to Central America, prized for its distinctive appearance—as it matures, characteristic holes develop in its leaves. It's remarkably hardy and easy to grow, thriving indoors with minimal fuss. Thanks to its excellent shade tolerance, it's become a go-to choice for plant beginners.
Monstera prefers bright, indirect light, but its shade tolerance means it'll do fine tucked away in a corner too. Aim for temperatures between 15–25°C, with a minimum of 10°C in winter. Humidity between 50–70% is ideal, and it's happiest away from direct air-conditioning drafts.
Light and temperature change a plant's metabolism, so the ideal cadence shifts with the seasons.
Spring
Every 4–6 days
Summer
Every 4–6 days
Autumn
Every 5–7 days
Winter
Every 10–14 days
Water thoroughly when the soil surface feels dry—keep going until water drains from the bottom of the pot. Always empty the saucer afterward to prevent root rot. Since the leaves are quite large, misting them once or twice a week keeps them looking fresh while naturally boosting humidity. Scale back watering during winter.
Quick lookup from symptom to likely cause and action.
| Symptom | Likely cause | What to try |
|---|---|---|
| Leaves turn yellow and drop off | Usually the result of overwatering causing root rot, or underwatering weakening the plant. Cold temperatures in winter can also trigger this. | Check your soil moisture level—if it's too wet, ease up on watering. In winter, move the plant to a warmer spot (above 10°C) and reduce watering frequency. |
| Leaves curl or have dry, crispy edges | The plant isn't getting enough humidity, often from direct air-conditioning airflow or dry indoor air. | Mist the leaves regularly to raise humidity levels, and relocate the plant away from direct AC vents. |
| New leaves are small or growth has stalled | Either insufficient light or the plant has become root-bound and isn't getting adequate nutrients. | Move it to a brighter location. If roots are cramped, consider repotting into a slightly larger container in spring. |
| Sticky residue on stems and leaves, with tiny insects visible | Scale insects or mealybugs have colonized the plant and are sapping its strength. | Gently wipe affected areas with a soft cloth to remove the pests. If the infestation is severe, consider using an insecticide spray. |
| Leaf undersides turn white or appear powdery | Fungal infection like powdery mildew, typically triggered by high humidity combined with poor air circulation. | Wipe affected areas clean and improve air flow around the plant. Apply a fungicide if needed, and avoid leaving foliage wet for extended periods. |
