The best time to transplant camphor trees is during the budding season, when the survival rate is at its highest—typically 10–15 days before and after Qingming. This period offers optimal conditions for root establishment and overall recovery. Below are the transplantation methods and technical measures that can be applied to ensure successful results.
First, let's explore the different transplantation methods:
1. **Dry Method**: This technique is commonly used for large camphor trees with a trunk diameter of 10 cm or more. Since these trees grow in place year-round, their root systems are extensive and deep, making them challenging to move. The dry method involves cutting the tree above ground, which allows for easier lifting and transport. It also reduces water and nutrient loss from the leaves, improving survival rates. However, the tree may appear less attractive for the first few years, and it may take over two years to regain a full canopy.
2. **Root Reduction Method**: This approach involves pruning the roots of the tree in advance before transplanting. When pruning, the basic structure of the tree should be maintained. The root cut should extend five times the diameter of the trunk, and rough roots should be removed. Afterward, a 0.1% naphthalene acetic acid solution is applied to the cut ends, and the area is covered with soil. After two years, the tree can be transplanted. This method increases survival rates and improves the greening effect, but it requires a longer preparation period and higher costs.
3. **Transplanting with Crown**: This method preserves the original canopy and is often used when immediate visual impact is needed. It is particularly suitable for smaller trees, but for larger ones (15 cm or more in diameter), specialized lifting equipment is necessary. Before transplanting, weak branches should be pruned, and about 50% of the leaves should be retained to reduce water loss. The root ball should be at least eight times the diameter of the trunk, and proper soil wrapping is essential for a successful transplant.
Now, let’s look at the key technical measures to follow during the transplanting process:
1. Apply 0.1% naphthalene acetic acid or rooting powder to the roots before planting to encourage new root growth.
2. Treat any wounds on the tree with a mixture of 0.1% naphthalene acetic acid and lanolin to prevent decay.
3. Add decomposed organic fertilizer at the bottom of the planting hole to enrich the soil and support healthy growth.
4. Plant the tree at an appropriate depth, ensuring that the top of the root ball is exposed by 1/2 to 1/4. Planting too deep can lead to root rot.
5. Water thoroughly after planting, then cover the root area with fine soil to help retain moisture and prevent excessive water infiltration.
6. Wrap the trunk with wet straw ropes and cover them with a thin plastic film to keep the bark moist and protect it from sun damage. Be careful not to use damp grass rope, as it may cause bark rot.
7. For large trees with a full crown, install sprinklers at the top of the canopy and apply foliar sprays on sunny days to maintain leaf moisture.
8. Provide shade if necessary, especially for trees with a full canopy. A shading shed can reduce light intensity and minimize water loss through the leaves.
9. Apply foliar fertilizer after new leaves begin to grow. Spraying 0.1% urea solution on the leaves helps replenish nutrients and supports new growth. Avoid doing this in the fall.
10. Prune newly grown shoots to remove weak branches and promote strong growth. Remove any adventitious buds that appear on the trunk to maintain a clean and healthy structure.
By following these methods and techniques, you can significantly increase the chances of successful transplantation and ensure long-term health and beauty of your camphor trees.
