What if the core of peony flower turns black?

Peony is a very common flower in China, and there are many people who breed it. During the growth period of peony, there are often many problems affecting the growth of peony. This leads to a decline in production and thus a decrease in ornamental value. The blackening of the peony core is one of them, so what if the peony core is blackened? The following editor will give you a brief introduction, let's have a look!

1. Pruning treatment

We should often observe the growth of peonies when we are conserving them. When the flower core is found to be blackened, it must be dealt with in time, if it is not dealt with in time, then the plant is very easy to be infected with diseases and insect pests, seriously endangering the growth of peony flowers, resulting in a decrease in ornamental value. It should be pruned frequently to improve the permeability between plants. Then it is found that the blackened part of the flower core should be trimmed off in time after blackening, so as to avoid the plant consuming too much nutrition, resulting in a decline in resistance and promoting the plant to gradually restore its original growth.

2. Lighting control

Light is one of the main reasons for the blackening of peony flower core. In the cultivation of peony flowers, if the light is insufficient or too weak, then it is also very easy to cause the core of peony flowers to turn black. When the flower core is found to be blackened, check the cause of the blackening in time, if it is caused by light. Then it is necessary to provide sufficient sunshine for the plant in time, promote the photosynthesis of peony, improve the flowering rate of peony, avoid and prevent the vigorous growth of peony and improve the ornamental value of peony.

3. Water and fertilizer management

Peony is the same as other plants in its growth, which is inseparable from the irrigation of water and fertilizer. If there is a lack of fertilizer and water in the growth, it is also very easy to lead to the blackening of the peony core. Therefore, when we are conserving peony flowers, we must pay attention to irrigating more fertilizer and water to meet the requirements of peony growth. If there is a blackening phenomenon, then it should be watered in time, but be careful not to flood irrigation, mainly drip irrigation with small water. Then it is necessary to apply nitrogen, phosphorus and potassium fertilizer properly, even if the peony has little demand for water and fertilizer, but the right amount of water and fertilizer is also very important for the growth of the peony.

4. Disease and pest control

Peony is often harmed by diseases and insect pests in its growth, which is also the main reason for the blackening of peony flower core. The blackening of peony flower core caused by diseases and insect pests will not only lead to a decline in ornamental value, but also seriously harm the normal growth of the plant, and sometimes lead to death. At this time, we should not only do a good job of pruning and ventilation, but also timely check specific diseases and pests, and then spray corresponding pesticides for pest control.
