This article will provide you with a detailed analysis of the reasons for the yellowing of茉莉 leaves in autumn and winter and offer corresponding prevention and control measures.
Reasons for the yellowing of茉莉 leaves in autumn and winter1. Environmental factors
In autumn and winter, the temperature gradually decreases, and the day-night temperature difference is significant. Such environmental changes may cause the leaves of茉莉 flowers to turn yellow. Insufficient light and dry air may also cause the leaves to turn yellow.
2. Improper water management
Both excessive and insufficient watering can cause the leaves of茉莉 flowers to turn yellow. Excessive watering can easily lead to root hypoxia and root rot, while insufficient watering will cause the茉莉 flowers to lack water, resulting in gradual yellowing of the leaves.
3. Improper application of fertilizers
Too much or too little fertilizer will affect the growth of茉莉 flowers. Excessive fertilization can easily cause fertilizer damage and leaf yellowing, while insufficient fertilization will make茉莉 flowers lack nutrition, leading to gradual yellowing of the leaves.
4. Pest and disease attacks
In autumn and winter,茉莉 flowers are susceptible to pest and disease attacks, such as aphids and red spiders. These pests will absorb the nutrients of茉莉 flowers, causing the leaves to turn yellow.
