Dracaena, also known as麒麟掌 (Kylin Palm), is a common indoor ornamental plant loved by many families for its unique tree shape and bright leaves. Many plant enthusiasts have noticed that the leaves of Dracaena can turn yellow during the maintenance process. This not only affects the plant's appearance but may also threaten its growth. This article will thoroughly analyze the reasons for the yellowing of Dracaena leaves and provide corresponding solutions.
Reasons for the yellowing of Dracaena leaves1. Improper water management
Dracaena is sensitive to water demand. Excessive or insufficient watering can lead to yellowing of the leaves. Too much watering can cause root hypoxia and lead to root rot; too little watering will make the leaves lose water and turn yellow.
2. Insufficient lighting
Dracaena prefers a semi-shaded environment. Excessive direct sunlight can damage the leaves, resulting in yellowing.
3. Improper application of fertilizer
Excessive or improper fertilization can cause an imbalance of nutrients in the soil, leading to poor plant growth and yellowing of the leaves.
4. Pest and disease infestation
Pests and diseases are also among the reasons for the yellowing of Dracaena leaves, including common pests like red spiders and scale insects.
5. Environmental factors
Changes in environmental factors such as temperature and humidity can also affect the growth of Dracaena, such as too high or too low temperatures, and inappropriate humidity.

3. Reasonable fertilization
During the growing season, apply a compound fertilizer once a month. Be careful not to over-fertilize, and after fertilizing, water promptly to prevent fertilizer residue.
4. Pest and disease control
