Causes and treatments for yellow leaves of peony flowers

1. Forgetting to fertilize

1. Reason: Peony is a relatively fertilizer-loving flower. Fertilizer is needed during its growing season and bud formation period. If no fertilizer is applied for a long time, it may lack nutrients and cause yellow leaves.

2. Treatment method: First water the plants with some thin liquid fertilizer and spray a small amount of foliar fertilizer. After that, increase the frequency of fertilization, provide nutrients, and help it recover.

2. Sunburn

1. Reason: Its growth and flowering require sunlight. However, if the light given to it is too strong, its leaves may turn yellow, which is not conducive to its growth.

2. Treatment method: First cut off all the yellow leaves, and then use the shading net to adjust the light intensity of the maintenance environment so that the light is sufficient but not too strong to burn the plants.

3. Unsuitable soil

1. Reason: It likes slightly acidic soil and does not like to grow in alkaline soil. If the pH of the soil in which it is grown is too high, it may develop yellow leaves because it cannot adapt to the soil conditions.

2. Treatment method: Place the plant in a pot, clean the roots, and then place it in a well-ventilated place to dry. After that, prepare some slightly acidic flower soil and plant it in it for maintenance.
