Kalanchoe is loved by many gardening enthusiasts for its long blooming period and auspicious meaning. Many gardeners encounter a problem during the care of Kalanchoe: the leaves turn yellow when the plant is flowering. What exactly causes this? And how should we deal with it? This article will unveil the secrets behind the yellowing of Kalanchoe leaves and provide practical care tips to help keep your Kalanchoe evergreen throughout the year.
Reasons for the yellowing of Kalanchoe leaves1. Improper water management
Kalanchoe prefers a humid environment, but excessive watering or waterlogging can lead to root rot, which in turn causes the leaves to turn yellow. Improper watering can also lead to soil compaction, affecting the absorption of water and nutrients by the roots.
2. Insufficient light
Kalanchoe requires ample sunlight. If it is kept in a dark environment for a long time, the leaves can easily turn yellow. This is because insufficient light weakens photosynthesis, thus affecting the plant's growth.
3. Soil issues
Poor soil, poor drainage, or compacted soil can lead to yellowing of Kalanchoe leaves. High salinity or excessive acidity in the soil can also affect plant growth.
4. Pest and disease attacks
Common pests and diseases include aphids, spider mites, and whiteflies, which extract nutrients from the plant, causing the leaves to turn yellow.
5. Improper temperature
The optimal growth temperature for Kalanchoe is between 15-25°C. If the temperature is too high or too low, it will affect the plant's growth and cause the leaves to turn yellow.
Solutions for the yellowing of Kalanchoe leaves1. Water appropriately
Water according to the dryness or moisture of the soil, avoid waterlogging, and try to water thoroughly while preventing water from splashing onto the leaves.
2. Increase light exposure appropriately
Place Kalanchoe in a sunny location but avoid direct sunlight. If indoor lighting is insufficient, you can use a plant growth lamp to supplement light.
3. Improve the soil
Choose well-drained, breathable soil, change the soil regularly, maintain soil fertility, and apply organic fertilizer appropriately to promote plant growth.
4. Control pests and diseases
Regularly inspect the plant and take timely measures when pests and diseases are found. Use pesticides and fungicides for prevention and control, and ensure proper ventilation to reduce the occurrence of pests and diseases.
5. Control temperature
Place Kalanchoe in a suitable temperature environment and avoid high or low temperatures.
Kalanchoe care tips1. Prune regularly

3. Maintain ventilation
Keeping indoor air circulation helps reduce the occurrence of pests and diseases.
If the leaves of Kalanchoe turn yellow during flowering, it may be due to reasons such as improper water management, insufficient light, soil issues, pest and disease attacks, or improper temperature. After understanding the causes, take appropriate solutions and master the care tips for Kalanchoe, and your plant will surely remain evergreen and bloom beautifully throughout the year.
