How many degrees below zero can peonies tolerate cold?

Theoretically, peonies can withstand low temperatures of about minus 30 degrees.

Peony flowers can generally withstand a cold of about minus 20 degrees, and some peony varieties can withstand a cold of about minus 30 degrees. Peony is a relatively cold-resistant plant with strong cold tolerance and can survive temperatures as low as minus 30 degrees. normal growth in the environment. Under normal circumstances, peonies are not afraid of freezing in the cold winter. However, to be on the safe side, in colder areas, measures should be taken to keep warm and keep out the cold. When maintaining peonies in winter, you can place them outdoors for maintenance. In order to prevent frostbite, water the peonies once before winter. Short plants can be cultivated in soil from the end of October to early November to prevent cold. You can lay a layer of straw at the roots of the peonies. Peonies with taller plants can be covered with film to keep warm. Potted peonies can be moved indoors to a sunny place. . Peonies are suitable for growing in a relatively humid environment, but water evaporates slowly in winter. Therefore, when maintaining peonies in winter, it is necessary to provide them with reasonable moisture. It is best to provide moisture to peonies in the afternoon when the temperature is higher. , just keep the soil moist. Peonies are light-loving plants. If they receive insufficient light during their growth, they will suffer from poor growth or their leaves will turn yellow. Therefore, when maintaining peonies, you need to provide them with appropriate light so that they can photosynthesize normally. function to store enough nutrients for winter. Peonies may suffer from diseases in winter, so when maintaining peonies in winter, you need to prune the plants appropriately and cut off the branches and leaves that grow too densely. At the same time, you also need to regularly spray pesticides on peonies to eliminate peony plants. The pathogens on the peonies allow peonies to grow healthily.

Although peonies are normally cold-tolerant and not afraid of freezing, peony seedlings that have just been transplanted that year or peony seedlings that are not growing well have relatively poor cold and frost resistance. Transplanted peony seedlings or peony seedlings with poor growth still need to be protected from the cold in the cold winter.

In addition, not all peony varieties are so frost-resistant. Some peony varieties are also more afraid of freezing, such as the yellow peony variety: Haihuang. This variety is very susceptible to frost, even if it is In Shandong, when the temperature is several degrees below zero in winter, people sometimes freeze to death. Therefore, for peony varieties that are not frost-resistant, they must be protected from the cold in winter to prevent them from being frozen.
