Why are the peony leaves turning yellow?

1. Too much light

Peony is a relatively light-loving plant, but under strong light, the plant's growth and development will still be problematic. Exposure to the sun in summer can easily cause the leaves to lose water, causing them to turn yellow. In this case, the plant needs to be placed in semi-shade to avoid continued exposure to sunlight, or it can be given appropriate shade. After it resumes growth, you can expose it to the sun in the early morning or evening.

2. Lack of water

Lack of water will cause yellow leaves on any plant, and peony is no exception. Although it has fleshy roots and is relatively drought-resistant, long-term lack of water will cause the leaves to turn yellow. If the yellowing of leaves is caused by lack of water, the plant will recover quickly with proper watering. Normally, water thoroughly when the soil is dry. This will meet the water needs without making the soil too moist.

3. Pruning too early

If the peony is pruned too early, the nutrients absorbed by the plant will not have time to be transferred to the leaves, which will cause the upper leaves to turn yellow. Therefore, you must pay attention to the time when pruning to ensure that the plant recovers and grows vigorously. The pruning should not be too large, otherwise it will affect the photosynthesis of the plant.

4. Improper fertilization

Peony cannot do without various nutrients during its growth process. The lack of any element will cause its leaves to turn yellow. At the same time, excessive fertilization can also cause root burn, which can lead to yellow leaves. During its growth period, the amount of fertilizer must be controlled. Adequate dilution can reduce the harm caused by concentrated fertilizers. In addition, the use of compound fertilizers can also fully supplement nutrition.
