What fertilizer is best for peony?

Peony fertilization time

1. Peony needs to be fertilized three times a year, usually during the growing season. The first time is in late March to early April in spring, the second time is in late April, and the third time is in November in autumn.

2. According to the fertility requirements of peony at different development stages, topdressing should be applied according to the season every year. Its flowering period is in May. Since flowering requires a lot of nutrients, "flower fertilizer" should be applied before flowering.

3. Peony should be fertilized in time after the flowers fade. At this time, the plant is in a state of fertilizer deficiency. Fertilize in time to supplement nutrients. During the summer growth period, foliar fertilization should be carried out twice in combination with spraying.

What fertilizer to use for peony

1. Apply "flower fertilizer" before peony blooms. You can apply quick-acting fertilizer and appropriately increase the proportion of phosphorus and potassium fertilizers. This can promote the healthy growth of the plant and add a large amount of nutrients for bud development and flowering.

2. For peony after flowering, it is best to use high-phosphorus fertilizer as the main fertilizer, so that sufficient fertilizer can be replenished in time, making the next flower bloom more vigorously, which is related to the quality of flowering and growth in the next year.

3. During the summer growth period of peony, foliar fertilization should be carried out twice in combination with spraying. Fertilizers containing potassium can be applied. Generally, 1%-2% potassium dihydrogen phosphate solution can be sprayed to promote root absorption.

Peony Fertilization Method

The fertilization method for peony varies depending on the type of fertilizer. Solid fertilizer should be buried in the soil. If quick-acting fertilizer is used, it should be kept away from the roots to avoid damage. Liquid fertilizer should be diluted with water to be more easily absorbed. Foliar fertilizer is sprayed on the leaves of the plant.

Notes on fertilizing peony

When fertilizing peonies, you need to control the concentration. If you apply too much fertilizer, the roots can easily be burned. In this case, you need to remove the plant from the pot, cut off the roots with scissors, spray it with carbendazim solution to prevent wound infection, and then replant it with new soil.
