Recently, it has been hot summer, and many orchid enthusiasts have reported that the leaves of their orchids are turning yellow, probably due to root rot. Many新手 orchid enthusiasts lack experience in caring for orchids, and it is common for orchids to die in summer. How can we effectively prevent the yellowing of orchid leaves? The author summarizes four main reasons for the yellowing of orchid leaves:
First, the potting soil is too wet or too dry, with too much moisture causing root rot and too little moisture causing root shrinkage. The weakened absorption function of the roots leads to insufficient supply of water and nutrients, resulting in the yellowing of orchid leaves;
Second, direct sunlight in summer;
Third, damage caused by pests and diseases;

Fourth, leaf replacement, which means that every spring and autumn, there is always a batch of leaves from three to four-year-old plants that turn yellow, wither, and fall off, which is a normal metabolic process.

The last situation is a normal physiological phenomenon that cannot be avoided. For the first three situations, the following measures can be taken to solve them: adjust temperature and humidity to keep the potting soil moist and increase air humidity; strengthen shading to reduce light intensity; and promptly prevent and treat pests and diseases, especially paying attention to the prevention and treatment of scale insects.
In addition to the above reasons, poor ventilation, long-term lack of fertilization or repotting, unsuitable soil pH, and environmental pollution are also factors that can cause the yellowing of orchid leaves, and these should be addressed according to different situations.
The above sharing on why orchid leaves turn yellow and the specific introduction of the reasons and solutions for yellowing leaves of orchids are hoped to be liked by everyone!
