Base fertilizer before planting:

Before planting peony, make enough base fertilizer for the flowerpot. The base fertilizer is mainly rotten bone powder, stable manure and compost, which is covered with soil

Fertilization after flowering:

The flowering period of Paeonia lactiflora is generally around the first ten days of May. The flowering period is long, which can last for at least one month. Fertilization should be carried out 2 weeks after flowering. At this time, it is in the state of lack of fertilizer. Because when the flowers bloom, they almost absorb all the nutrients in the soil. At this time, high phosphorus fertilizer is the best fertilizer, which can lay a good foundation for the second flowering period and make the second flowering period bloom more vigorously

Fertilization in autumn and winter:

In autumn and winter, additional fertilization can be applied, so as to prepare for the next year's flowering

Fertilization techniques:

In daily nursing, we can observe the color of the soil to judge whether there is lack of fertilizer. The color of the soil is dark, which can reduce the amount of fertilizer. When the condition of plants can be observed, if the color and plumpness of plants are different, fertilization should be increased

Precautions:

After each fertilization, we should actively carry out relevant work, such as watering and loosening the soil in time. Especially in the early stage of flowering, we must do a good job in fertilization. A lot of nutrients are needed at the flowering stage. After the flower is unloaded, the pedicel should also be cleaned in time to avoid the loss of unnecessary nutrients
