Can camphor freeze to death at minus 5 degrees Celsius?
In the area south of the Yangtze River. Cinnamomum camphora grows tall and straight without frost damage. "Of course, the statement 'no freezing damage' is just a summary of experience in the usual sense and is not absolute. For example, in some years, areas south of the Yangtze River may also encounter extreme low temperature weather. Camphor will also suffer from extreme low temperature weather. Suffered a certain degree of freezing damage," Jin Biao explained.
According to researchers’ observations, camphor’s cold tolerance is at minus 10°C as the critical point. When the minimum temperature is below minus 10°C, the trunks of saplings and the twigs and leaves of large trees are susceptible to freezing damage. Generally, as a tree gets older, frost damage becomes less common. Moreover, there is little individual difference in the cold and freezing tolerance of camphor trees of similar age.
Small trees are like babies and children, with poor physical ability to withstand cold; large trees are like young men in their prime, with good physical fitness and strong cold resistance. "However, as long as the low temperature below minus 10 degrees Celsius does not last long, the small trees affected by the freeze can continue to sprout and eventually grow into big trees as long as the frozen branches are cut off.
Interesting Yes, if camphor trees in areas north of the Yangtze River are introduced and transplanted from nurseries in adjacent areas, the survival rate will be greatly improved. "This actually shows that because of the geographical proximity, there is no significant climate difference, allowing camphor trees to grow to the maximum extent. Adapt to the local climate after transplantation.
