Causes and treatments for yellow leaves of purple-leaf plum

1. Insufficient light

Reason: Purple-leaf plum likes to grow in warm places, likes sunlight, and is not cold-resistant. Therefore, the place where purple-leaf plum grows needs to be kept in sufficient sunlight and the temperature should be maintained between 22 and 28 degrees Celsius. If there is insufficient light, it will cause yellow leaves problem.

Measures: Purple-leaf plum must not be placed in a shady place without light. Only sufficient sunlight can promote its growth. Therefore, it needs to be placed in a sunny place such as a balcony, but be careful to avoid direct sunlight.

2. Moisture problem

Reason: Purple-leaf plum needs sufficient watering to grow, especially during its growing period, it needs to be watered in time. If you don't water it in time, you may have yellow leaves problems. However, during the rainy season in July and August every year, you can simply stop watering it and pay attention to drainage. If the roots rot, it will also cause the leaves to turn yellow.

Measures: Pay attention to the growth status of the purple-leaf plum. If it is short of water, water it in time, control the amount, and not too thoroughly. If the purple-leaf plum has root rot problems during the rainy season, it should be pruned in time.

3. Improper fertilization

Reason: Purple-leaf plum likes fertilizer, and sufficient fertilizer can promote its plant growth. If there is no fertilizer or insufficient fertilizer, it will have yellow leaves due to lack of nutrients. However, even if it likes fertilizer, you cannot apply too much fertilizer. Excessive fertilizer can easily burn the seedlings and cause yellow leaves.

Measures: When fertilizing purple-leaf plum, you can apply an appropriate amount of fertilizer according to normal standards and use less chemical fertilizers. In late autumn, apply an appropriate amount of organic fertilizer. At the same time, pay attention to observation. If too much fertilizer is applied, stop fertilizing and immediately add water to dilute the fertilizer.

4. Soil issues

Reason: Purple-leaf plum likes to grow in deep, fertile, acidic soil with good drainage. If the soil is too alkaline, dry, and has poor water storage performance, the root absorption capacity of purple-leaf plum will be reduced, resulting in yellow leaves.

Measures: At this time, it is necessary to replace the soil with one that is slightly acidic, has a certain degree of fertility and is not easy to accumulate water. And during subsequent maintenance, change the soil every 1-2 years to ensure that the soil always meets its growth requirements. If it is a plant planted in the ground, you can consider lowering the pH value of the soil by watering it with ferrous sulfate solution to make it more suitable for the growth requirements of the plant.
