How does peony survive the winter? What should I do if it sprouts in winter?

1. How does peony survive the winter?

1. Peonies are usually planted in the ground, so it is very easy to survive the winter. In the autumn of each year, when the stems and leaves of the peony on the ground turn yellow, keep about 5 cm of the stems and cut off all the yellow stems and leaves. You don't have to take care of it anymore. Because the fleshy roots underground of peony are very resistant to frost, they can safely survive the winter even in the Northeast region and will sprout again in the spring of the following year.

2. If it is a potted peony, it is important to note that the peony must not be kept in a heated room in winter, otherwise the flower buds of the peony will not undergo low-temperature vernalization during the winter and will not bloom in the second year. Peony potted plants must be stored in an environment of 2°C for 1-2 months. No watering is required during the low-temperature storage period to allow the peony to successfully undergo vernalization so that it can bloom normally.

2. What to do if peony sprouts in winter

There are only two reasons why peony sprouts in winter. First, the maintenance temperature is too high during the winter. We must find a way to lower the temperature so that the peony can successfully enter vernal dormancy and sprout again when the spring comes. The second is that the peony is divided too early in autumn. The temperature is too high after division, causing the peony to sprout. The best time to divide the peony is from early September to late October. If the peony is divided too early, it will sprout and emerge from the ground in the same year and will easily be frozen. If the peony is divided too late, it will not be able to sprout new roots, which will reduce the plant's ability to survive the winter and make it easy to freeze to death.
