Causes and treatments for yellow leaves of Toona sinensis

Causes and treatments for yellow leaves of Toona sinensis

1. Too little water

1. Reason: Toona sinensis requires sufficient water to grow. If there is too little water, the root system cannot effectively supply water to the tree, resulting in the transpiration of the leaves being greater than the water supply from the roots, and yellowing symptoms will appear.

2. Treatment method: In the later stage, water should be irrigated in time, shade nets should be set up, branches with leaves should be pruned and the saw cuts should be sealed with paint.

2. Too little fertilization

1. Reason: Certain nutrients are needed during the growth period to help growth. If the soil is too poor and no fertilizer is applied in time during maintenance, the plant may also have yellowing leaves due to lack of nutrition.

2. Treatment method: prepare some liquid fertilizer and pour it into the soil. Then increase the frequency of top dressing, preferably once every 10-15 days.

3. Leaf rust disease

1. Reason: The main disease of Chinese toon is root rot, which will harm the roots of Chinese toon, causing root rot, and unable to provide nutrients normally, which will cause the leaves of Chinese toon to turn yellow.

2. Treatment method: Diseased leaves should be removed in time, fertilizer and water management should be strengthened, and 10% alkaline water, 10% anthracene oil or 5% thiophanate should be applied for prevention and control.
