What Causes the Yellowing of Moorchide Leaves

The yellowing of Moorchide leaves is caused by metabolism, soil waterlogging, and insufficient nutrition. The shedding of old leaves and the growth of new leaves are normal natural phenomena. You can cut off the yellow leaves to prevent attracting pests. If excessive watering occurs, it is important to drain the water promptly. In severe cases, you can remove the plant from the pot and change the soil. Note that Moorchide grows vigorously in spring and August each year, and the frequency of fertilization should be moderately increased.

Reasons for the Yellowing of Moorchide Leaves

1. Metabolism: If there are no other symptoms and the Moorchide is not growing too poorly, there is no need to worry. The shedding of old leaves and the growth of new leaves are normal natural phenomena and part of the plant's self-regulation mechanism to adapt to the surrounding environment.

2. Soil Waterlogging: Although Moorchide requires ample water during its growth, its roots are not tolerant to waterlogging. Therefore, it is crucial to prevent soil waterlogging. Roots in a waterlogged environment can easily rot, preventing the plant from absorbing water from the soil, which leads to yellowing leaves.

3. Insufficient Nutrition: In August each year, Moorchide enters a stage of vigorous growth. If the soil lacks fertilizer, it cannot support the plant's normal growth and development, leading to yellowing leaves.

Methods to Treat Yellowing Leaves of Moorchide

1. Prune Yellow Leaves: If Moorchide is only experiencing normal shedding, there is no need to worry too much. Cutting off the yellow leaves can prevent attracting pests, and careful care for a period of time can restore the plant to normal.

2. Drain Water Promptly: First, clear and drain the accumulated water around the Moorchide, then observe the condition of the rotting roots. If the situation is severe, dig out the plant along with some soil, cut off the yellow leaves, and then transplant it into well-draining soil, reducing the watering frequency.

3. Apply Fertilizer Moderately: It is important to note that Moorchide is in a stage of vigorous growth during spring and August each year. During this period, the frequency of fertilization should be moderately increased, with a focus on applying dilute fertilizers and avoiding concentrated ones.

Prevention and Control of Yellowing Leaves in Moorchide

Moorchide prefers a sunny environment. In spring and winter, the plant can be placed in full sunlight all day. In summer and autumn, when the sun is too strong, it should be given appropriate shade. This type of plant grows normally at temperatures between 20-28°C. In winter, it can be moved indoors to ensure it survives the cold.

The comprehensive explanation of the reasons for the yellowing of Moorchide leaves shared above aims to act as a starting point to help solve your green plant problems.
