Why do orchid leaves turn yellow? How to remedy the problem after they turn yellow?

1. Overwatering

1. Reason: If the leaves of the orchid turn yellow, it may be because the frequency of watering is not controlled well and too much water is poured in. If this water cannot be absorbed in time, it will remain in the soil and cause the plants to be waterlogged. This results in it being unable to absorb nutrients normally, resulting in yellow leaves.

2. Treatment method: First prepare some flower soil with good drainage and no water accumulation, replace it for the plants, and then control watering during the subsequent maintenance process.

2. Forget to fertilize the flowers

1. Reason: It needs certain nutrients to synthesize pigments to make the leaves appear normal green. If you forget to apply fertilizer when growing it, it will not be able to synthesize these pigments normally, and its leaves will turn yellow.

2. Treatment method: Add some flower fertilizer to it in time. But don't apply concentrated fertilizer, but apply thin fertilizer. You can apply it more often, but not too much at one time.

3. Too much light

1. Reason: It prefers shade. If the leaves are exposed to the sun for a long time, they will be burned and turn yellow.

2. Treatment method: Cut off the severely injured leaves, then move it to a semi-shaded place, slowly maintain it, and wait for it to recover.
