Can peonies be planted in northern courtyards (how to manage peonies in northern courtyards over the winter)

Peonies can be planted in the north of China . Peonies are relatively cold-resistant and can even withstand temperatures as low as minus ten degrees Celsius . Purple-spotted peonies can even be grown outdoors in the northeast.

Therefore, there is no need to worry about frost damage. The most important thing is that peonies like the soil in the north , and a slightly colder climate is conducive to the peony's beautiful dormancy.

Moreover, peony is a common garden flower . Although it is elegant and dignified, it is not delicate. It can be planted in the open field or in pots for viewing .

In daily management, we only need to respect its growth habits, follow the laws of nature, and manage it scientifically. So, how to manage peonies in the north in winter?

Key points for winter management of northern garden peonies

In the north, the winter management of garden peonies can follow the following points.

1. Pruning

Although peony is cold-resistant, it does not mean that it is cold-resistant to an extreme. In the north, from mid-November, the plant begins to enter a dormant or semi-dormant state.

At this time, not only the leaves turn yellow and the branches wither, but the sap also gradually stops flowing. Therefore, this is the best time to prune.

When pruning, first remove the dead leaves that have not fallen, then cut off the dry, diseased and weak branches and densely growing crossed branches, and finally cut off the overly long branches that affect the appearance of the plant.

2. Kill insects

In winter, the pupae and eggs of many pests will hide in the ground around the plants. At this time, you can take advantage of the dry and cold weather in the north to deep plow the surrounding soil and freeze the insects.

After several turns and cooling, spray disinfectant and insecticide. In this way, many hidden dangers of diseases and insects can be prevented.

3. Water and fertilizer

In terms of water and fertilizer, peonies in winter have already "fallen asleep" and consume almost no water and nutrients.

Therefore, water and fertilizer can be almost omitted. But when there is nothing to do in winter, bury some decomposed farmyard manure around the rhizomes, they will not refuse it, anyway, there is no risk of burning roots and fertilizer damage.

4. Weeding

Although the winter in the north is dry and cold, there are also tenacious plants that can tolerate drought and cold. In the winter, you can remove or pull them out, which not only makes the courtyard clean and tidy, but also prevents the breeding and hiding of pests and diseases.

5. Keep warm

Although peonies are cold-resistant, freezing weather that is too cold often injures the plants, affecting their growth and flower bud differentiation next year. Therefore, it is best to cover them with large black plastic bags or straw after pruning and disinfection.

Precautions for winter care of peony flowers

1. Avoid frequent watering

In winter, peonies are almost in a "no food, no drink" state and do not require much water. Therefore, it is advisable to water them less or not at all. Avoid frequent watering.

2. Avoid cutting off all stems and branches

Peony is not a peony, but a woody shrub in the genus Paeonia. Therefore, it is best not to cut off all its stems and branches.
