1. Earthing up to prevent cold: The temperature in the northern region is relatively low, so earthing up must be carried out regardless of the size of the plant.Usually, the height of the earth is about 15 to 20 centimeters.This height can be determined according to the cold degree of the region, if the temperature is too low, more cultivation, pay attention to before freezing.
2. Wrap the branches: For some small plants, wrap the branches to prevent freezing.First gather and bind it, then wrap it tightly with grass felt or some weeds, wrap the outermost layer with plastic bags, and compact it with soil, so as to better windproof.
3. Greenhouse: If there are many peony seedlings or the plant shape is large, it is very troublesome to operate. A simple greenhouse can be built to prevent cold. The specific size depends on the number of seedlings and the plant shape.When it's set up, just put it all in.
The peony is a deciduous shrub that loses its leaves in winter, stops growing, and goes dormant.Only winter dormancy, accumulate more nutrients, so that the next spring can blossom.Therefore, the temperature must be well controlled in winter management, neither too high nor too low.If it is too high, it will germinate ahead of time and consume nutrients.If it is too low, it will be frostbitten and harmful to next year's flowering.
