Hanging orchids, with their elegant shape and fresh floral fragrance, have become the favorites of many families and offices as green plants. During the maintenance process, many flower enthusiasts encounter the problem of the middle leaves of the hanging orchid turning white. This not only affects the overall aesthetics of the hanging orchid but also causes concern about its health. This article will analyze the reasons for the whitening of the middle leaves of the hanging orchid and provide effective solutions.
Reasons for the whitening of the middle leaves of the hanging orchid1. Insufficient lighting
Hanging orchids prefer scattered light. If they are in a dark environment for a long time, it can lead to leaf whitening. This is because hanging orchids need ample sunlight to synthesize chlorophyll to maintain the green color of the leaves.
2. Improper watering
Watering is a crucial aspect of caring for hanging orchids. If the watering is excessive or insufficient, it can lead to leaf whitening. Excessive watering can cause root hypoxia, affecting the normal growth of the hanging orchid, while insufficient watering can lead to water deficiency and leaf whitening.
3. Soil issues
Soil is the foundation for the growth of hanging orchids. If the soil is too compact, has poor breathability, or lacks necessary nutrients, it can lead to leaf whitening in hanging orchids.
4. Pest and disease problems
Hanging orchids may be troubled by pests and diseases, such as leaf spot disease and red spider mites. These pests and diseases can cause leaf whitening and, in severe cases, even lead to the death of the hanging orchid.

Place the hanging orchid in a place with sufficient scattered light and avoid prolonged exposure to dark environments. If indoor lighting is insufficient, consider using a plant growth lamp to supplement the light.
2. Watering in a timely manner
Based on the growth habits of hanging orchids, keep the soil moist but not overly wet. Watering 1-2 times a week is sufficient, and during the hot summer, you can increase the frequency of watering.
3. Improve the soil
Choose soil with good breathability and drainage, such as decomposed leaf soil and pearl rock, and fertilize regularly to supplement the nutrients needed by the hanging orchid.
4. Control pests and diseases
Regularly inspect the hanging orchid and deal with pests and diseases promptly. You can use insecticides and fungicides for prevention and treatment while maintaining a clean environment to reduce the occurrence of pests and diseases.
The whitening of the middle leaves of the hanging orchid is a common maintenance issue.
