hydrangea . In addition to the variety of endless summer , if the local temperature of other horticultural hydrangeas drops to single digits, it is recommended that you move to your home in advance. The temperature at home is higher, which can ensure that hydrangeas are not frostbite. Especially for flower lovers in the northern region, pay special attention to temperature changes.
The impact of low temperature on plants is fatal. Don't ignore it. Most flowering plants are afraid of high temperatures. The temperature may be more than 20 degrees during the day, and at night, the temperature will drop rapidly and become six or seven degrees. Many plants will have leaves wrinkled and yellow at such temperatures, and will wither over time, and finally only the bare trunk is left.
The autumn cooling will definitely affect plants, especially in northern regions, such as north of the Yangtze River . In November of each year, the temperature at night is basically around six or seven degrees, and the temperature is still very low. Most of the plants and flowers we place on the terrace in the yard are affected by the low temperature for a long time. Most of the symptoms of entering the dormant period are that the leaves fall off. Once the leaves of the plant fall out, it will not be possible to perform photosynthesis normally, and the root system cannot absorb nutrients, so it will stop growing. There will be no signs of growth throughout the winter. If you move it to your home in advance, this will prevent the leaves from falling off, and the flowers, plants and green plants in the home can still continue to grow with photosynthesis.
hydrangea is just a typical example. It is the least resistant to freezing among flowering plants. Especially at present, the gardening hydrangea we buy online or offline stores have worse ability to resist low temperatures. However, the old varieties of endless summer have slightly higher resistance to low temperatures. The varieties of hydrangeas are different, and their ability to adapt to the environment is also very different.
Like the current Northeast region, if your hydrangea is still outdoors, then 100% may be frostbite. It may seem that there are leaves on the main trunk, but the roots in the soil have begun to wither slowly. When the roots completely stop absorbing water, the green leaves will wither immediately. It is important for plants to keep warm in advance.
The temperature in the north and south regions of my country varies greatly. The temperature in the southern region is still very high. Most of the time I bloom, I still bloom in large quantities. The cooling in the southern region does not have a great impact on plants. The temperature at night is still 20 degrees. In such an environment, it will not affect the growth of plants. If the temperature at night drops to single digits, it will have a certain impact on the plants.
