Peperomia plants are popular houseplants known for their attractive foliage and easy care. However, if you notice your Peperomia’s leaves are dropping, it can be concerning. Understanding the common reasons for leaf drop can help you take the right steps to revive your plant and keep it healthy.
1. Overwatering
One of the most common causes of leaf drop in Peperomia is overwatering. These plants prefer well-draining soil and can suffer from root rot if kept too wet. Symptoms include wilting, yellowing leaves, and leaf drop. Always allow the top inch of soil to dry out before watering again.
2. Underwatering
Conversely, underwatering can also cause leaves to drop. When the plant does not receive enough water, it becomes stressed and sheds its lower or older leaves. Ensure you water your Peperomia thoroughly when the topsoil feels dry, but do not let it sit in water.
3. Improper Lighting
Peperomia plants thrive in bright, indirect light. Too much direct sunlight can scorch the leaves, causing them to drop. On the other hand, insufficient light can weaken the plant, leading to leaf loss. Place your Peperomia near a window with filtered light for optimal health.
4. Sudden Temperature Changes
Peperomia prefers stable temperatures between 65°F and 80°F (18°C to 27°C). Exposure to cold drafts, sudden temperature drops, or hot, dry air from heaters can stress the plant and cause leaf drop. Keep your plant in a consistent environment away from vents and drafts.
5. Pests and Diseases
Infestations of pests such as spider mites, mealybugs, or aphids can weaken the plant and lead to leaf loss. Fungal or bacterial diseases can also cause foliage to drop. Regularly inspect your Peperomia and treat any pests promptly with appropriate methods. Maintain good airflow and avoid overwatering to prevent diseases.
