Can camphor trees be planted in the north?

It can be planted, but it is not suitable.

The adaptive altitude of Cinnamomum camphora is below 1800 meters, and it can reach 1000 meters in the south and southwest growing areas of the Yangtze River. It mainly grows on sunny slopes, valleys and river banks, and the subtropical soil is fertile. It is also often planted on hillsides or valleys.

Cinnamomum camphora likes warm and humid climate conditions and is not cold-resistant. It is suitable to live in areas where the annual average temperature is above 16 ~ 17℃ and the absolute low temperature is above -7℃. Cinnamomum camphora is not strict with soil, and it grows well in deep and fertile clay loam, sandy loam, acidic soil and neutral soil, and can also grow in saline-alkali soil with salt content below 0.2%.

Matters needing attention in planting Cinnamomum camphora:

1, planting season:

According to the experience in recent years, Cinnamomum camphora is easy to survive when transplanted in late winter and early spring, and the best transplanting season is when the bud is about to germinate. There are many favorable factors at this time.

If the temperature is low, there is much rain, the soil temperature rises, the transpiration of branches and leaves is weak, and the root system has certain activity ability. When the sap begins to flow, its roots have begun to regain their vitality. At this time, the bud has just germinated, and the new root system can absorb water and nutrients to meet the needs of respiration, transpiration, leaf opening and germination on the ground.

2. Dig and wrap the earth ball:

Prune some branches before digging trees, and remove some leaves after digging, so as to reduce transpiration of branches and leaves, adjust the balance between the ground and underground parts, and improve the survival rate. The roots of the tree are very big, and it is easy to survive if it is dug into a soil ball of the right size. Generally, the perimeter of the ground diameter is taken as the radius of the soil ball, and a circle is made along the trunk, which is the appropriate size of the soil ball.

The height of soil ball should be determined according to the distribution of root system and soil properties, and generally 40 ~ 60 cm is appropriate. The excavation method should break the ground 3 ~ 5 cm away from the round edge, so that there is room for trimming the soil ball. With a four-toothed rake or a pointed hoe, people face the trunk to dig trenches, and the thick roots should be sawed off with a saw to avoid shaking the soil ball.

When the soil ball is dug to a height of 2/3, it is trimmed into a complete circle with appropriate size and vertical up and down, and tied tightly from top to bottom with thick straw rope to prevent the soil ball from shaking down during deep digging. Then, the lower part of the soil ball is deeply dug to make the pot bottom shape, but the main root is not stopped to keep the tree upright.

Then, like winding a round yarn ball, wrap the whole soil ball tightly with a thick straw rope, cut off the main root with a sharp weapon, and slowly fall down the tree to avoid shaking the soil ball, and then tie the crown tightly with a thick straw rope to wrap the trunk, so as to protect the trunk and crown from damage.
