1、 How do you spend the winter in the open air in the north
1. Cultivating soil to prevent cold: the temperature in northern China is relatively low, so it is necessary to cultivate soil regardless of the shape and size of the plant. Usually, the height of soil cultivation is about 15 to 20 cm. This height can be determined according to the cold degree of the area. If the temperature is too low, train more. Pay attention to it before freezing p>
2. Wrap branches: for some small plants, wrap their branches to prevent freezing. It's better to wrap the weeds tightly with plastic bags, so that they can be compacted first p>
3. Greenhouse: if there are many Peony Seedlings planted or the plant shape is relatively large, which is very troublesome to operate, a simple greenhouse can be built to prevent cold. The specific size depends on the number of seedlings and plant shape. Just put it all in after it is built p>
2、 Do leaves fall in winter
Peony is a deciduous shrub. It will lose its leaves in winter, stop growing and begin to sleep. Only winter dormancy, accumulate more nutrients, so that the next spring can bloom. Therefore, when managing in winter, we must control the temperature well, neither too high nor too low. Too high, it will germinate in advance and consume nutrients. If it is too low, it will be frostbitten, which is also bad for next year's flowering p>
