アエオニウム
Watering rhythm
Every 14–21 days
Aeonium is a striking succulent prized for its distinctive rosette-shaped foliage. Native to the Canary Islands, these plants come in a wonderful range of colors—from deep black leaves to golden varieties. What makes aeonium special is its unique growth rhythm: it grows actively in winter and goes dormant in summer. This means your care approach changes with the seasons.
Aeonium thrives in bright indoor spaces or outdoors in full sun. Keep temperatures above 10°C as a minimum, and avoid placing it outside during the coldest winter months. Low humidity is fine, but good air circulation is essential. Avoid environments warmer than 30°C, as heat and poor airflow can cause the plant to suffer.
Light and temperature change a plant's metabolism, so the ideal cadence shifts with the seasons.
Spring
Every 10–16 days
Summer
Every 14–21 days
Autumn
Every 10–16 days
Winter
Every 20–28 days
Let the soil surface dry completely between waterings. Since aeonium stores water in its fleshy leaves, overwatering quickly leads to root rot. During the growing season, you can water before the soil is bone-dry, but in the dormant summer period, let it stay drier for longer. You don't need to wait until the leaves shrivel—just err on the side of dryness.
Quick lookup from symptom to likely cause and action.
| Symptom | Likely cause | What to try |
|---|---|---|
| Leaves turn black and become mushy | The roots are staying too wet, causing rot to develop. This is especially common when people water too generously during winter dormancy. | Stop watering immediately and move the plant to an area with good airflow. If the rot has progressed significantly, remove the affected roots and repot into fresh soil. |
| Leaves look thin, droopy, and lose their color | The plant isn't getting enough light, or it's experienced a sudden change in conditions. Aeonium needs good light to maintain its vibrant colors. | Move it to a brighter spot, ideally near a window. Avoid shocking the plant with a sudden move—gradually introduce it to brighter light over time. |
| The stem stretches out and looks unbalanced | Insufficient light or warm temperatures are causing the plant to stretch. This happens frequently when aeonium is kept indoors during winter in dimmer conditions. | Move it to a brighter location. During the spring growing season, you can also trim back the stem to encourage side shoots and create a fuller shape. |
| White powdery coating or brown spots appear on leaves | Powdery mildew or scale insects have appeared. These usually show up when air circulation is poor or humidity is too high. | Gently wipe affected areas with a soft cloth. Improve ventilation around the plant and consider using a fungicidal spray if needed. |
| Leaves suddenly drop or the whole plant wilts in summer | Aeonium naturally goes dormant in hot, humid summer weather—and excessive water or poor airflow during this period can be fatal. | Accept that summer is dormancy time and water much less frequently. Prioritize good airflow and keep the plant out of direct sun during the hottest parts of the day. |
