If you own a kalanchoe plant and notice its leaves are dropping, you’re not alone. This list covers the six most common causes for leaf drop in kalanchoes and provides practical solutions to help revive your plant. Whether you’re a beginner or seasoned succulent grower, understanding these issues can keep your kalanchoe healthy and vibrant.
1. Overwatering Leading to Root Rot
Kalanchoes are succulents adapted to dry conditions, so excessive watering is a primary cause of leaf drop. When soil remains soggy, roots can suffocate and develop rot, preventing the plant from absorbing nutrients. To fix this, reduce watering frequency, ensure your pot has drainage holes, and use well-draining soil specifically designed for succulents, such as a cactus mix.
2. Underwatering Causing Leaf Stress
While overwatering is a common problem, underwatering can also cause leaves to shrivel and fall off. Kalanchoes store water in their leaves but still require consistent moisture during their growing season. If leaves become dry, crispy, or wrinkled, increase watering slightly, allowing the soil to dry out between sessions but never remain bone dry for long periods.
3. Insufficient Light Exposure
Kalanchoes thrive in bright, indirect sunlight and need at least 4-6 hours of light daily. Low light conditions weaken the plant, causing older leaves to yellow and drop. To correct this, move your kalanchoe near a south- or east-facing window or supplement with a grow light designed for succulents to maintain healthy foliage.
4. Sudden Temperature Changes or Drafts
Kalanchoes prefer stable temperatures between 60-85°F (15-29°C). Exposure to cold drafts, sudden drops below 50°F (10°C), or hot, dry air from heaters can shock the plant, resulting in leaf fall. Keep your kalanchoe away from windows or doors that open frequently in cold months and avoid placing it near heating vents or air conditioners.
5. Pest Infestations
Common pests like aphids, mealybugs, and spider mites can stress kalanchoes by feeding on sap, leading to leaf yellowing and drop. Inspect your plant regularly for small insects, sticky residue, or webbing. Treat infestations promptly with insecticidal soap, neem oil, or by wiping leaves with rubbing alcohol on a cotton swab.
6. Natural Leaf Aging and Pruning Needs
It’s normal for older, lower leaves on a kalanchoe to yellow and fall off over time as the plant grows. This natural process helps the plant focus energy on new growth. Regularly prune dead or dying leaves by gently pinching them off at the base to encourage healthy development and improve airflow around the plant.
How to Choose
When selecting a kalanchoe, prioritize a plant with firm, plump leaves and no signs of pests or disease. Look for vibrant green foliage and avoid plants with excessive leaf drop or discoloration, indicating stress. Choose a pot with drainage holes and consider soil mix quality—well-draining soil is essential for preventing root rot. Finally, think about the lighting conditions in your home to pick a kalanchoe variety that suits your environment, such as Kalanchoe blossfeldiana for brighter areas or Kalanchoe tomentosa for spots with indirect light.
Frequently Asked Questions
Q: Can I save a kalanchoe with most leaves dropped?
Yes, if the stem and roots are healthy, reduce watering and improve light. The plant can regrow leaves with proper care.
Q: How often should I water my kalanchoe?
Water when the top 1-2 inches of soil feel dry, usually every 7-14 days depending on environment.
Q: Does kalanchoe need fertilizer?
Yes, during active growth, feed monthly with a balanced, water-soluble fertilizer diluted to half strength.
Q: Why are my kalanchoe leaves turning yellow before falling?
Yellowing often indicates overwatering, nutrient deficiency, or low light.
Q: Can kalanchoe survive indoors year-round?
Yes, with adequate light and proper watering, kalanchoes adapt well as indoor houseplants.
Final Thoughts
Leaf drop in kalanchoes is usually a sign of environmental stress or care issues. By identifying whether the cause is watering habits, lighting, pests, or temperature, you can take targeted steps to restore your plant’s health. Remember, these resilient succulents thrive best in well-draining soil, bright indirect light, and moderate watering. With consistent attention, your kalanchoe will bounce back and continue to brighten your space with its charming foliage and flowers.
