Paeonia Suffruticosa are cold-hardy plants, and the paeonia rockii , in particular, can survive winters at -30°C without artificial protection. However, other varieties of chinese tree peonies may require protection to survive the winter.
Winter care methods for chinese tree peonies include the following:
- Watering and fertilization: During winter, tree peonies enter a dormant period, so reduce watering and keep the soil slightly moist, avoiding overwatering which can lead to root damage from freezing.
- Pruning: Timely prune dry and weak branches, retaining healthy flower buds to conserve nutrients.
- Temperature control: Potted tree peonies should be placed indoors in a warm environment, maintaining a temperature between 1-10℃ to promote flower bud development.
- Cold protection measures: When temperatures are low, mound soil around the base of the plant and tie the branches together with straw or weeds, then cover with a plastic bag to protect against cold winds.
- Weed removal: Regularly remove overwintering weeds to maintain healthy soil.
These methods can help tree peonies safely survive the cold winter and bloom beautifully in the following year.
