Causes and treatments of yellow banana leaves

1. Unsuitable soil quality

1. Reason: If bananas are grown in acidic soil, their growth will be affected and they will not be able to maintain nutrient supply, causing the leaves to turn yellow and become susceptible to diseases.

2. Treatment methods: First, apply soil conditioners to improve the properties of the soil at the bottom of the ridges; second, input a large amount of calcium fertilizer and magnesium fertilizer, and at the same time increase the frequency of fertilization and irrigation to expand the effective improvement range.

2. Excessive fertilization

1. Reason: Bananas do not require too much fertilizer to grow. If too much fertilizer is applied during cultivation, it will not have time to absorb the fertilizer. The excess fertilizer will remain in the soil, damaging the root system and causing yellow leaves.

2. Treatment method: Stop fertilizing first, then pour water into the soil to wash away the accumulated fertilizer in the soil.

3. Disease Problems

1. Reason: The yellowing of banana leaves is mostly caused by wilt disease, which will harm the rhizomes and leaves of bananas, affect the normal growth and development of bananas, and cause the leaves to turn yellow and wither.

2. Treatment method: You can choose high-efficiency fungicides to treat crop wilt diseases, while promoting bananas to resume growth better and faster and enhance disease resistance.
