When and how to fertilize peony, what fertilizer does peony like?

1. Fertilization time

The best time to fertilize peony is during the growing season. If it is planted in the ground, it should be fertilized three times a year, the first time in late March to early April, the second time in late April, and the third time in November. If it is potted, it should be regularly topdressed according to the growth conditions of the plant.

2. Fertilizer selection

Different fertilizers are applied to peonies at different times. Usually when the plants are planted, sufficient basal fertilizer needs to be applied. The basal fertilizer is usually decomposed bone meal, manure and compost. Before the plant blooms, you need to apply some quick-acting fertilizer, mostly compound fertilizer or foliar fertilizer. After the flowers of the plant fade, nutrients need to be replenished in time, and high-phosphorus fertilizer should be applied at this time.

3. How to fertilize

The method of fertilizing varies depending on the type of fertilizer. Solid fertilizers are usually buried in the soil. If it is a quick-acting fertilizer, it needs to be kept away from the roots to avoid damaging them. Liquid fertilizer can often be directly applied to the plants. Since it combines with water, it is more easily absorbed. Foliar fertilizer is sprayed on the leaves, and the effect is also very good.

IV. Precautions

The concentration of fertilizer should be controlled when applying fertilizer to any plant, and peony is no exception. Once too much fertilizer is applied, the roots of the plant can easily be burned. In this case, it is often necessary to remove the plant from the pot in time, cut off the burned roots with scissors, and spray the plant with carbendazim solution to prevent wound infection. Then use loose and fertile new soil and replant.
