If we want to learn to plant peony flowers, the first thing we need to know is the habit of peony. After knowing the habit of peony, we can keep a clear idea of peony at any time. Next, I will elaborate on the habits of peony from several aspects to help you raise peony well. First, light peony is definitely not a shade-loving plant. On the contrary, it has a strong demand for light, so it is not only impossible to keep peony indoors, but also not in the north balcony, which lacks light. It needs to be kept in the south balcony and receive sufficient full sunshine. Only in this way can peony flowers produce the most beautiful flowers. If there is insufficient light in your home, it is not recommended to raise peony flowers, because even if you raise them, they will bloom badly, and the loss will outweigh the gain. Secondly, the water demand of watered peony is great during the growing period, especially potted peony. Because the size of the flowerpot is very limited, peony is easy to lack water, so the watering technique of potted peony is to see it dry and wet, which means to replenish water immediately when you see the flowerpot dry, and don&;t wait until the flowerpot is completely dry, so as not to cause water shortage in the root system. If it is planted in the ground, water it more frequently, as long as it is not below the slope and will not cause water accumulation. Thirdly, the soil peony has requirements for the soil. The soil it likes is loose, breathable, fertile and slightly acidic, and it is afraid of alkaline soil, where peony will bloom badly. Family potted Paeonia lactiflora can use ferrous sulfate once every other quarter to adjust the acidity of soil and adapt the soil to the acidity requirements of Paeonia lactiflora. Fourthly, the air permeability and leaf density of Paeonia lactiflora are very high, which also determines that it is a plant that needs air permeability very much and cannot be kept in an excessively closed environment. If your house is a closed balcony, you must open more windows for ventilation, otherwise peony will be easily infected with pests and diseases if it grows in a closed environment for a long time, which will lead to yellow and black leaves and eventually lead to serious consequences of seedling death. Fifth, fertilizing Paeonia lactiflora is a kind of fertilizer-loving plant. No matter whether it is planted in ground or potted, it must have the habit of continuous fertilization, especially in the growth and reproductive period of Paeonia lactiflora, it must be fertilized almost every 10 days. Fertilizer is mainly granular compound fertilizer, or plant nutrient solution, or phosphorus and potassium fertilizer, and thin fertilizer is applied frequently. Fertilization can not only promote the growth of Paeonia lactiflora, but also improve the stress resistance and disease resistance of Paeonia lactiflora. Sixth, I planted peony in the south for many years in winter. Experience tells me that peony has certain cold resistance, but it is also very limited. Potted peony can spend the winter in the open air in the south, and the cold resistance of ground planted peony will be stronger, but whether it is ground planted or potted, peony needs to spend the winter in greenhouse in the north, otherwise it will be easy to get frostbite.
