It prefers loose, deep, well-drained and fertile soil.When potted plants are planted, attention should be paid to the selection and preparation of soil, which can ensure normal growth and flowering.In addition, we should pay attention to the acidity and alkalinity of the soil.It likes to be neutral or slightly alkaline, do not like acidic soil, to control the acidity and alkalinity at any time, otherwise it is easy to grow poorly and hinder flowering.
1. When mixing soil for peony flowers, six parts of garden soil, three parts of rotten leaf soil and one part of rice chaff ash can be mixed, so as to ensure the porosity, drainage and not easy to accumulate water.
2. Four parts of rotten leaf soil and four parts of garden soil can also be used, and then a proper amount of coarse sand is mixed to improve the drainage property. After mixing, a small amount of rice husk ash is added, which can also meet its needs.
3. In addition to the above two methods, garden soil, barnyard manure and coarse sand can also be mixed according to the ratio of 1:1:1, so that the plants can grow vigorously in the later period.
III. Precautions
In addition to the method of soil preparation, attention should also be paid to the disinfection of the soil.Before potting, the soil should be exposed to strong light, so that the high temperature environment can kill insect eggs and eliminate pathogens.If the weather does not permit, disinfectant can also be used for disinfection.Potassium permanganate solution is commonly used, diluted and sprayed on the soil, and can be used safely after drying.
