Why are the camellia leaves turning yellow?

Why are the camellia leaves turning yellow?

1. Caused by pests and diseases

(1) Specific reasons: The leaves may turn yellow due to the influence of some diseases and pests, such as "red spider" and "leaf blight".

(2) Solution: Spray specific pesticides for different diseases and pests, and pay attention to light, ventilation, etc.

2. Too much watering

(1) Specific reasons: Yellowing of leaves due to watering mainly refers to excessive watering, severe water accumulation, and root rot.

(2) Solution: Stop watering first, and then place it in a ventilated, cool place for a while. After the plant has almost recovered, slowly resume watering, and avoid water accumulation.

3. The soil is alkaline

(1) Specific reason: Camellia prefers acidic soil. Alkaline soil can easily cause the leaves to turn yellow.

(2) Solution: Change the potting soil for the plant regularly, replacing it with slightly acidic soil, and also pay attention to the nutrients it contains.

4. Lack of nitrogen

(1) Specific reasons: When the plant is in the growth stage, if there is a lack of nitrogen, the leaves may turn yellow.

(2) Solution: This element needs to be supplemented, such as bean cake water. In addition, some ferrous sulfate can be added.

5. Normal phenomenon

(1) Specific reasons: Camellia leaves generally do not fall off in a short period of time, but they may also be replaced. At this stage, the leaves turn yellow, which is a normal metabolic phenomenon.

(2) Solution: In this case, no special measures are needed, just normal maintenance will be sufficient.
