In the community of flower enthusiasts, Dracaena fragrans is highly favored for its unique tree shape and lush green leaves. Many flower lovers find that the leaves of Dracaena fragrans sometimes turn yellow during the maintenance process, which not only affects the ornamental value but may also indicate health issues in the plant. Why do the leaves of Dracaena fragrans turn yellow? This article will unveil this mystery and provide corresponding prevention and treatment methods.
Reasons for the yellowing of Dracaena fragrans leaves1. Improper water management
Dracaena fragrans is sensitive to water requirements, and both excessive and insufficient watering can cause the leaves to turn yellow. Excessive watering can lead to root hypoxia, affecting the normal growth of the plant; while insufficient watering can cause the soil to dry out and the leaves to lose water.
2. Insufficient lighting
Dracaena fragrans prefers a semi-shaded environment. Prolonged direct sunlight or insufficient lighting can cause the leaves to turn yellow. Excessive sunlight can burn the leaves, while insufficient lighting can affect photosynthesis, leading to yellowing of the leaves.
3. Soil issues
Poor soil quality, soil compaction, or unsuitable pH levels can cause the leaves of Dracaena fragrans to turn yellow. Suitable soil should have good breathability and drainage, with a pH value between 5.5 and 6.5.
4. Improper fertilizer application
Excessive or improper application of fertilizer can cause the leaves of Dracaena fragrans to turn yellow. Overuse of nitrogen fertilizer can lead to excessive plant growth, while a lack of other elements can affect normal plant growth.
5. Pest and disease infestation
Dracaena fragrans is susceptible to infestation by pests such as red spiders and scale insects. These pests absorb nutrients from the plant, causing the leaves to turn yellow.
