Why the leaves of orchids are yellow and how to remedy them
First, reasons
1. Growth and metabolism
Yellowing of plant leaves may also be a normal phenomenon in the process of growth, so just let it grow freely, wait for new leaves to grow, and trim off the yellowing leaves.
2. Moisture
When you give the plant too much water, it will fill the soil and water too little to dry the soil, which will cause the leaves of the plant to turn yellow.
3. Lighting
If the light is too hot, the leaves of the plant will be damaged, and the plant will turn yellow due to lack of nutrients when the light is insufficient.
4. Fertilizer
Too much fertilizer or too much fertilizer concentration will burn the leaves of the plant, and too little fertilizer will cause the leaves to turn yellow due to lack of nutrients.
5. Low temperature freezing injury
If the temperature is not high in winter, it will also cause the plant to turn yellow due to freezing injury.
6. Influence of diseases and insect pests
Yellowing leaves may also be infected with diseases and insect pests.
II. Remedial measures
1. Water the flower soil when you see it turn white. Watch the soil water.
2. The plants were placed in soft light and shaded in summer.
3. Apply fertilizer once in about 15 days and dilute it with fertilizer and water.
