What causes orchid leaves to turn yellow?

1. Insufficient nutrients

1. Reason: If you forget to fertilize orchids for a long time and the soil lacks nutrients, it will be difficult for the plants to obtain the necessary nutrients from it. Its leaves also turn yellow due to lack of nutrients.

2. Treatment method: Increase the frequency of fertilizing it to ensure that the nutrients provided are sufficient to meet its growth needs. But be careful not to apply it too frequently, otherwise the excess fertilizer will remain in the soil and cause damage to the roots of the plant.

2. Too much light

1. Cause: If this problem occurs in summer, this is most likely the reason. It prefers partial shade and does not like and cannot withstand prolonged exposure to strong sunlight. If the light is too strong, it will burn its leaves and turn them yellow.

2. Treatment methods: There are mainly two methods. One is to use a shading net to block some of the light when the light is too strong. Instead, change its location and place it in the shade of a tree or some other place where it won't be hit by direct sunlight.

3. Dry the accumulated water

1. Reason: Its root system is not very strong and it is afraid of waterlogging. If you water it too frequently and water accumulates in the soil, it will become waterlogged and rot, causing the leaves to turn yellow.

2. Treatment method: Place the flower pot in a ventilated place and blow dry the moisture in it. Then reduce the frequency of watering and wait for it to recover slowly.
