Hydrangeas have a dormant period.
Hydrangeas bloom from June to August.After the flowering period, hydrangea branches and leaves began to wither and yellow slowly.When winter comes, hydrangeas will gradually enter the dormant period, and their nutritional needs for water and nutrients will gradually decrease.
During this time, watering can be controlled to reduce the amount of water, as long as the surface of the pot soil is kept wet.If you water too much, the roots can not be absorbed in time, it will form water, in the case of low temperature is very easy to frostbite the roots.Fertilization should also pay attention to the winter dormancy period can not be fertilized, otherwise it will lead to its inability to hibernate, and then because it can not resist the cold temperature and freeze to death.Attention should be paid to placing it in a suitable temperature environment so that it can survive the winter safely.
The dormancy period of hydrangea is usually in winter, from November to January of the next year, about three months before and after.During this period, if the plant is cultivated in the open field, it should be given soil to keep warm.If it is a potted hydrangea, you can maintain it indoors in the south to the sun, to avoid its cold wind and low temperature.
However, in the early winter, when the temperature is not very low, it can continue to be tested by the cold outdoors.In this way, it can enhance its cold resistance and help it blossom smoothly in the coming year.When the temperature is below six degrees or even zero, it must be moved to indoor maintenance.
