Why are the leaves of the four-season plum turning yellow?

1. The culture soil is alkaline

1. Specific reasons: The requirements of the four-season plum for the soil include the requirements for its pH, and acidic or neutral soil is best. If alkaline soil is used, especially saline-alkali soil, it will greatly affect its health and easily cause its leaves to turn yellow.

2. Solution: It is best to replace the soil in time and choose acidic or neutral soil. Alternatively, you can lower the pH of the soil and add vinegar to the water to achieve this effect.

2. No potting for a long time

1. Specific reason: It is best to replace the culture soil of Prunus armeniaca regularly. If you don't change it for a long time, the soil will become clumping, which will hinder the root breathing and the leaves may turn yellow.

2. Solution: Repotting should be done regularly, preferably once every one to two years. You should also pay attention to the choice of soil, loose and breathable soil is better.

3. Too much watering

1. Specific reason: Four-season plum is particularly afraid of waterlogging. If there is too much water, its roots will rot and its leaves will turn yellow.

2. Solution: Stop watering and place it in a ventilated place to dry. After that, wait until the soil is dry before watering again, and never allow water to accumulate.

4. High fertilizer concentration or large amount

1. Specific reasons: Both situations will cause fertilizer damage. This can then endanger the leaf, causing it to turn yellow.

2. Solution: Water the plant to wash away the fertilizer. When applying fertilizer later, it must be diluted sufficiently and the amount must be moderate.
