What kind of fertilizer should be applied in peony flower bloom?

Peony flowering period to apply rotten organic fertilizer, it is best to use solid fertilizer, to control the concentration of diluted fertilizer, fertilizer can be shallow applied in the roots, can also be sprayed on leaves to avoid burning seedlings, so that plant growth is exuberant. Fishbone meal can also be added to increase the content of phosphorus and potassium fertilizer, promote plant flowering, and cooperate with watering to reduce the concentration.

How to apply fertilizer at flowering stage of peony

1. When to apply fertilizer

The most important thing for peony to apply winter fertilizer is to apply solid fermented organic fertilizer, apply sufficient base fertilizer and cultivate soil at the same time. When peony blossoms in spring, it is necessary to apply solid fermented organic fertilizer once, peony rarely applies liquid fertilizer, and topdressing is often buried with solid fertilizer. You can also spray leaves with diluted fertilizer to control the concentration and avoid burning seedlings.

2. Fertilizer selection

Fermented organic fertilizer can choose fermented pig manure, sheep manure or compost to provide rich organic matter for the soil, improve soil fertility and make plants grow better. At the same time, some bone meal can be added, fish bone meal can increase the content of phosphorus and potassium fertilizer, and phosphorus and potassium fertilizer can also be added to the fertilizer to promote plant flowering.

3. Sensitive to water and fertilizer

Peony is a fleshy root, and the underdeveloped root system is very sensitive to water and fertilizer. Do not use fertilizer with too high concentration when fertilizing, whether it is extra-root topdressing or organic fertilizer, we must pay attention to the amount of fertilizer. When organic fertilizer is used, it must be fully fermented, which is beneficial to the absorption of roots, and fertilization should be combined with watering to reduce the concentration.

4. Avoid summer fertilizer

Peony can not be fertilized in summer, the temperature in summer is relatively high, the growth is exuberant, the transpiration rate will be accelerated, and the plant water loss is serious, but the peony is still in the stage of growth stagnation in summer. At this time, if you continue to apply fertilizer, it will cause the situation of burning seedlings, plants can not absorb water from the soil, can not absorb nutrients, affecting plant growth.
