Why do orange trees drop leaves?

Why do orange trees drop leaves?

1. Excessive watering

Reason: Too much or too little watering will cause the orange tree to drop leaves. In addition, the quality of the soil and the size of the pot will also affect the roots' absorption of water.

Solution: Choose a pot that is the right size for your orange tree and a soil that is breathable and well-drained. Do not water too much at ordinary times to avoid water accumulation.

2. Excessive Fertilization

Cause: Too much fertilizer, or the fertilizer itself is not fully decomposed, resulting in root burns, which further causes leaf loss.

Solution: Change the soil in time to avoid fertilizer burning the roots. At the same time, choose organic fertilizer that is easily absorbed. Do not apply too much fertilizer at a single time. It is enough to apply it twice a week.

3. Pests and diseases

Reason: Red spider mites are the main pest that causes massive leaf fall. In addition, anthracnose can also cause leaf fall.

Solution: Different pesticides are needed to control different diseases and pests. Red spider mites can be killed with a diluted solution of mite control, and a diluted solution of lime sulfur can be used to eliminate overwintering larvae. Anthracnose needs to be treated by diluting thiophanate-methyl wettable powder with water and spraying it.

4. The temperature is too low

Reason: Mainly, the unseasonal low temperatures can cause leaves to fall.

Solution: For ground plants, you can build a plastic greenhouse around them to keep them warm, and move potted plants into a warm place indoors.
