The reason and treatment of peony yellow leaf

Forget to apply fertilizer: not applying fertilizer for a long time may cause the peony to turn yellow. At this time, we should add some flower fertilizer to it, and increase the frequency of later fertilization. Sunburn: too much light can cause yellow leaves. At this time, first cut off the yellow leaves, and then use the shading network to properly shade the light. Soil discomfort: improper soil may cause yellow leaves. At this time, we should take it out of the basin and wash its roots, and then plant it into the soft and thick, weak acid new flower soil.

I. forget to fertilize

1. Reason: peony is a kind of relatively fat flower. Fertilization is needed when it is in the growing season and when it is pregnant. If it does not fertilize for a long time, resulting in its lack of nutrition, it may appear yellow leaves.

2. Treatment method: first, water some thin liquid fertilizer for the plant, and spray a small amount of foliar fertilizer. After that, improve the frequency of fertilization, provide nutrients, and help it recover.

2. Strong sunlight and sunburn

1. Reason: its growth and flowering need sunshine. However, if the light given to it is too strong, it may Tan its leaves, which is not good for its growth.

2. Treatment method: first cut off 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.

III. soil discomfort

1. Reason: it likes slightly acidic flower soil and does not like to grow in alkaline soil. If the soil pH is too high, it may be unable to adapt to the soil conditions and yellow leaves.

2. Treatment method: wash the root system in the plant soil basin, and then put it in a well ventilated place to dry. After that, prepare some weak acid flower soil and plant it into it for maintenance.
