How to keep camphor trees warm in winter?

In recent years, the safe wintering of camphor trees has become a difficult problem in garden maintenance, especially in northern regions. If you are not careful, the branches, leaves and other parts of the camphor tree will suffer from frost damage. So how to keep camphor trees warm in winter? Let’s take a look below.

1. Why is camphor tree susceptible to freezing in northern regions?

1. The winter in the north is colder than that in the south: Camphor tree is a tree species with poor cold resistance. Generally speaking, when the low temperature of -7℃ lasts for more than 3 days, the branches and leaves of camphor trees are likely to suffer frost damage.

2. Yellowing tree species are more susceptible to frost: Due to the acidity and alkalinity of the soil in the northern region, the roots of camphor trees cannot absorb iron in the soil, and the leaves are prone to yellowing. The yellowing camphor leaves will not only turn yellow, but also become thinner than healthy leaves, and their resistance to the cold air from the outside will be weakened.

3. Snowfall increases the probability of freezing: There is relatively more snowfall in northern regions in winter. As an evergreen tree species, camphor trees will have a large amount of snow accumulated on their leaves after snowfall, which greatly increases the probability of frost damage to camphor trees.

2. How to prevent frost damage in winter when planting camphor trees in northern regions?

1. Improve the chlorosis of camphor trees: March to September in the northern region is the growing season of camphor trees. The roots and leaves absorb various nutrients better, which is the best period for the prevention and control of chlorosis. At this time, it can be improved by watering with ferrous sulfate, Qilin Sui Da and other measures.

2. Before the weather turns cold, spray antifreeze on the leaves: When the weather turns cold and deciduous trees begin to shed their leaves, you can use antifreeze (such as Qilin Antifreeze Frost) to spray the leaves of camphor trees to enhance the cold resistance of the leaves.

3. For the trunk and branches of camphor trees, you can use wrapping cloth, plastic film, etc. to wrap them to resist the cold. The protected parts are mainly the trunk of the seedlings and large branches. The wrapping height should be as high as possible, and then removed after the temperature stabilizes in the spring of the second year.

4. Clean up promptly after snowfall: After snowfall in northern regions, greening workers should be organized in time to use bamboo poles and other tools to knock down the snow on the tree crowns to avoid excessive snow accumulation and breaking of branches . At the same time, it can also reduce the damage of snow to the leaves of camphor trees.

That’s it
