If the foliage is too dense, it will cause the air to not flow smoothly, causing the lower leaves to turn yellow.

2. The soil is airtight

The fact that the soil is not permeable is also one of the reasons. Guangdong Evergreen is a plant with fleshy roots. It needs good drainage and breathable soil. Otherwise, it will affect the healthy growth of plants and cause yellow leaves.

In this regard, Xiaobian summarized three reasons for the whitening of Guangdong evergreen leaves, and attached solutions, we then look down.

Second, Guangdong Evergreen leaves white reasons and solutions

1. The environment is too bad

To say why Guangdong Evergreen leaves turn white, in fact, the most important reason is environmental problems. This can be divided into the following two points:

① Guangdong Evergreen potted plant bought from the Internet, due to the large geographical cross-service, the environment changes too much, the plant temporarily can not adapt, may appear the phenomenon of white leaves.

② Guangdong Evergreen shade tolerance, very suitable for indoor breeding, even if long-term in the dark, but also normal growth. But indoor than outdoor, especially in winter, often do not appear ventilated situation. A long time, Guangdong evergreen leaves may be white.

3. Basin soil discomfort

In addition to environment and light, the discomfort of basin soil is also one of the reasons for the whitening of evergreen leaves in Guangdong. There are also two situations:

① Guangdong Evergreen likes wet environment, but it is fleshy root, can not soak in water, so its cultivation soil needs loose, good drainage. Once the pot soil hardens, it is easy to appear in the pot water situation, the result is that the plant root rot, the leaves above will also appear white signs.

② Guangdong Evergreen likes slightly acidic soil. If the soil is alkaline, or the soil is alkaline due to long-term irrigation of mineral water, the plant will grow poorly, and the yellow and white leaves of Guangzhou Evergreen will appear as a result.

Solution: If it is caused by pot soil discomfort, it is very simple, replace the soil, change the water loose fertile, slightly acidic soil with good drainage. And timely loose soil, I believe that soon, the plant will return to health.
