1. Causes of orchid leaves turning yellow

1. Improper lighting

Why is it said that orchid leaves turning yellow is due to improper lighting? This is mainly judged from the orchid's growth habits. Orchids like a semi-shaded environment, and light that is too strong or too weak can cause leaves to turn yellow. For example, exposure to the sun in summer causes the leaves to dry up and turn yellow, or being placed in a place without light for a long time causes nutrients to be insufficient and the leaves to turn yellow.

2. Improper watering

The growth of orchids cannot be separated from daily watering. They have high requirements for air humidity and like a relatively moist environment. If watered too much, water will accumulate in the pot, which will naturally rot the roots and cause the leaves to turn yellow; if the air is too dry and watering is insufficient, it will also cause the leaves to turn yellow.

3. Improper fertilizing

Too much fertilizer can cause the leaves to turn yellow. The growth of orchids does not require too heavy a fertilizer, and soil that is too fertile can easily burn its roots and stems.

4. Caused by pests and diseases

Any plant may encounter pests and diseases during growth. Generally, the diseases that cause orchid leaves to turn yellow include anthracnose, leaf spot disease, and so on.

Natural growth cannot be separated from aging. This is true of people, and the same is true of plants. Therefore, the appearance of yellow leaves in orchids is also a natural growth process. Metabolism will cause new leaves to replace old leaves, yellow leaves to wither and fall, and green new shoots to climb onto the branches.
