Causes and treatments for yellowing orchid leaves

1. Too much light

1. Reason: Compared with an environment with sufficient light, orchids are more suitable for growing in a semi-shaded environment. If the sunlight is too strong where it is grown, it may get sunburned and its leaves may turn yellow.

2. Treatment method: Move the sunburned plants to a semi-shaded place and keep them ventilated. Then use scissors to cut off the leaves that have turned yellow and wait for new leaves to grow.

2. Too much watering

1. Reason: Orchids are relatively delicate and cannot grow normally in a substrate with stagnant water. If you water too much during maintenance and water accumulates in the substrate, it may be waterlogged and its roots may rot, resulting in yellow leaves.

2. Treatment method: First take the plant out of the original pot and cut off all the rotten roots and yellow leaves on it with scissors. Then plant it in new soil without water accumulation, stop watering for a while, and wait for it to recover.

3. Fertilizer is too concentrated

1. Reason: It likes fertilizer, but not concentrated fertilizer, because concentrated fertilizer may burn its roots. If the concentration of fertilizer applied to it is too high during maintenance, it may damage its root system, causing its leaves to turn yellow.

2. Treatment method: First use water to flush out the remaining fertilizer in the soil, then place it in a ventilated place to dry the soil, then temporarily stop fertilizing for a while and wait for it to recover.
