With the continuous pursuit of life quality by people, potted plants have gradually become popular in home decoration. Dendrobium, as one of them, has been favored by many flower enthusiasts due to its unique shape and elegant temperament. During the maintenance process, some enthusiasts may find that the leaves of Dendrobium turn yellow, which undoubtedly troubles those who love flowers. What should be done if the leaves of the potted Dendrobium turn yellow? This article will reveal the reasons for the yellowing of Dendrobium leaves and the solutions.
Reasons for Dendrobium Leaves Turning Yellow1. Improper Water Management
Dendrobium is native to tropical rainforests and requires a high amount of water. Excessive or insufficient watering can lead to yellowing of the leaves. Excessive watering can cause root hypoxia, affecting the normal growth of the plant; while insufficient watering can cause the leaves to lack water and turn yellow.
2. Insufficient Lighting
Dendrobium prefers a semi-shaded environment. If it is kept in a dark place for a long time, the leaves are prone to yellowing. Strong direct sunlight can also damage the leaves.
3. Soil Issues
Soil is the foundation for the growth of Dendrobium. If the soil has poor drainage and poor breathability, it can limit root growth, which in turn affects the normal growth of the leaves.
4. Improper Fertilizer Application
Excessive or insufficient fertilizer application can cause the leaves of Dendrobium to turn yellow. Excessive fertilizer can lead to high soil salinity, affecting root absorption; while insufficient fertilizer can cause malnutrition in the plant.
5. Pest and Disease Attacks
Dendrobium is susceptible to pest and disease attacks, such as leaf spot disease and red spider mites. These pests and diseases can cause the leaves to turn yellow and wither.
Solutions1. Adjust Watering Frequency Appropriately
Adjust the watering frequency based on the growth stage of Dendrobium and climatic conditions. Generally, keeping the soil slightly moist is sufficient.
2. Increase Lighting Appropriately
Place Dendrobium in a place with ample scattered light, avoiding strong direct sunlight. During the high-temperature period of summer, appropriate shading can be applied.
3. Improve Soil Conditions
Choose soil with good breathability and drainage, such as decomposed leaf soil and perlite. Regularly loosen the soil to ensure soil aeration.
4. Fertilize Reasonably
Apply fertilizer in a timely manner according to the growth needs of Dendrobium. Organic fertilizer or compound fertilizer can be used, avoiding excessive application.
5. Prevent Pest and Disease Attacks
Regularly inspect Dendrobium. If pests and diseases are found, handle them promptly. Biological pesticides or chemical pesticides can be used for control.
There are many reasons for the yellowing of Dendrobium leaves, but as long as the correct maintenance methods are mastered, this issue can be effectively avoided. I hope this article can provide help for your Dendrobium maintenance, allowing your beloved flowers to regain their vitality.
