What is the yellowing of orchid leaves?

The yellowing of orchid leaves may be due to improper watering, affecting root respiration, and the discomfort of potted soil will also lead to root decay, resulting in yellowing. If yellowing occurs in summer, it may be caused by excessive light. It needs to be moved to a cool environment, and 5 hours of astigmatism is needed in winter.

Causes of yellowing of orchid leaves 1. Improper watering

In the process of breeding, it may be caused by improper watering. Orchids have relatively high requirements for water. If they are watered too much, the respiration of the roots will be affected, and the leaves will turn yellow. At this time, it is best to discharge the excess water, and then water it according to the principle of dry and wet.

2. Root rot

The yellowing of orchid leaves may also be due to the fact that the root system has rotted, which can be removed from the basin to check whether the root system is rotten, and then pruned the rotten root system and treated with carbendazim at the same time. Planting with loose and high drainage capacity soil can improve the yellowing phenomenon of orchid leaves.

3. Shading and sunscreen

The yellowing of orchid leaves likes to grow in a semi-shady environment, but if exposed to strong light in summer, the leaves of the plant will turn yellow and scorch, which needs to be moved to a cool environment for a period of time. It can improve the yellowing of leaves.

4. Lack of light

Although orchids like to grow in a semi-shady environment, they can not be short of light for a long time, otherwise the leaves are short of light, which affects the formation of chlorophyll. It is best to move it into the environment of astigmatism and irradiate it for about 5 hours a day. It can improve the yellowing of leaves.
