Will hydrangeas die in winter?
This article introduces the topic of caring for hydrangeas at home. Will hydrangeas die in winter? Let's find out together.
In recent years, hydrangeas have become quite popular among flower enthusiasts, and many have gathered a lot of experience in caring for them. Today, let's talk about whether hydrangeas will die in winter and other related questions such as whether they lose their leaves in winter and how to care for them.
Hydrangeas are relatively cold-tolerant, but it's important to distinguish between potted and in-ground plants, as well as between large and young plants. In-ground large plants have the highest cold tolerance, while potted plants have the lowest. Based on the feedback from flower enthusiasts, hydrangeas planted in the ground can survive the winter outdoors in Beijing, Tianjin, and Hebei without any issues (if the temperature is extremely cold in the area, you can wrap the trunk with old clothes). For potted hydrangeas, they can survive the winter outdoors in the Jiangsu, Zhejiang, and Shanghai regions, but in the northern regions, they should be moved to a relatively warm place like a balcony to spend the winter, as the winter there can easily freeze the entire pot solid.
So the answer to the first question is that whether hydrangeas die in winter depends on extremely cold weather and varies by region and plant condition.
The second question is whether hydrangeas lose their leaves in winter?
Hydrangeas are deciduous shrubs of the Hydrangeaceae family, so they do lose their leaves in winter.
Below are some cares tips for hydrangeas in autumn and winter (from a post by Kunpeng on the bar forum)
1. Once the leaves of hydrangeas turn red in winter, they should be manually removed to prevent bud rot caused by gray mold and to eliminate the source of the pathogen. Flower enthusiasts in warmer regions may need to wait until mid-to-late January for the leaves to turn red.
Note: The "red leaves" mentioned in this article are a sign to determine whether the hydrangea has entered complete dormancy. A completely dormant hydrangea is not affected by light cycles, water, and fertilizer on bud differentiation.
2. If the leaves have not turned red during winter care, please place the plant in the sunniest spot in your home, as sufficient sunlight can promote bud differentiation and reduce the formation of "blind branches".
3. Flower enthusiasts in Guangdong, Guangxi, Fujian, and other regions, whose leaves are still green, can apply fertilizer, using monopotassium phosphate to water the roots once a week.严格控制氮肥的使用, and it is recommended not to use nitrogen fertilizer.
4. In regions where the plants have lost their leaves and are bare, you can dig a trench along the pot and bury an appropriate amount of organic fertilizer, but avoid using fertilizers like Huaduo.
5. Flower enthusiasts whose hydrangea leaves have not turned red should control the water management, keeping the soil slightly dry. A slightly dry soil environment can increase the concentration of vacuoles in hydrangea cells, which is beneficial for bud differentiation.
6. In areas where it is cold enough to freeze, you don't need to worry about the potted soil of hydrangeas outdoors after it freezes. However, it is still recommended to protect young plants during the winter.
