Why is my small-leaf Ficus dropping leaves?
Ficus benjamina (weeping fig) and other small-leaf ficus species are sensitive and it is perfectly normal for them drop leaves and recover. There are several factors contribute to this behavior:
1. Changes in Environment
Benjamina and other small leaf Ficus are sensitive to changes in its environment, including light, temperature, and humidity. A sudden shift, such as moving the plant to a new location or a significant change in lighting conditions, can cause stress and result in leaf drop.
2. Light Conditions
- Too Little Light: Insufficient light can cause leaves to yellow and fall off. Ficus benjamina prefers bright, indirect light. If it is in a dimly lit area, it may shed leaves in response.
- Too Much Direct Sunlight: While it likes bright light, too much direct sunlight can scorch its leaves, leading to damage and leaf drop.
3. Overwatering or Underwatering
- Overwatering: This is a common cause of leaf drop. Ficus benjamina likes to dry out slightly between waterings, and soggy soil can lead to root rot, causing leaves to turn yellow and fall off.
- Underwatering: On the other hand, if the plant is not getting enough water, the leaves may become dry, brittle, and drop off. Consistent watering habits are key to avoiding this.
4. Temperature Fluctuations
Ficus plants prefer stable temperatures between 60-75°F (15-24°C). Sudden temperature changes, cold drafts, or exposure to hot air (e.g., from heaters) can stress the plant, leading to leaf loss.
5. Low Humidity
Ficus benjamina thrives in moderate to high humidity. Dry indoor air, especially in winter when heaters are running, can cause the leaves to dry out and fall. Increasing humidity with a humidifier or misting the plant can help mitigate this.
6. Pests
In some cases, pests such as spider mites, scale, or mealybugs can infest the plant and cause leaves to drop. Check the undersides of leaves and the stems for any signs of pests.
7. Natural Leaf Drop
Ficus trees naturally shed older leaves as part of their growth cycle. If the leaf drop is minimal and the plant is otherwise healthy, it might just be natural aging.
8. Transplant Shock
Repotting or moving the plant can sometimes cause stress that leads to temporary leaf loss as the plant adjusts to its new environment.
To minimize leaf drop, try to keep the plant's environment as consistent as possible, monitor its watering needs, and provide it with bright, indirect light.
