1、 Fertilization time
The time of applying fertilizer to peony is mostly in the growth period. If it is planted in the ground, apply fertilizer three times a year, the first from late March to early April, the second in late April and the third in November. If it is potted, apply fertilizer regularly according to the growth status of the plant p>
2、 Fertilizer selection
In different periods, the fertilizer applied to Paeonia lactiflora is also different. Usually, when planting plants, it is necessary to apply sufficient base fertilizer, which usually selects rotten bone meal, manure and compost. Before flowering, a little quick acting fertilizer should be applied, and compound fertilizer or foliar fertilizer should be used more. After the plant withers, nutrients need to be supplemented in time. At this time, high phosphorus fertilizer should be applied p>
3、 How to fertilize
Depending on the type of fertilizer, the method of fertilization is also different. Solid fertilizer is usually buried in the soil. If it is quick acting fertilizer, it needs to be far away from the root to avoid damage to it. Liquid fertilizer can often be directly irrigated. It is easier to be absorbed because it is combined with water. Foliar fertilizer is sprayed on the leaves, and the effect is also very good p>
4、 Precautions
Control the concentration of fertilizer for any plant, and Paeonia lactiflora is no exception. Once fertilized excessively, the root of the plant is easy to be burned. In view of this situation, it is often necessary to take off the basin in time, cut off the burned roots with scissors, and spray carbendazim solution to avoid wound infection. Then plant again with loose and fertile new soil p>
