Transplantation, pruning and planting of evergreen trees and shrubs

Pruning evergreen trees and shrubs before transplanting

It is necessary to prune the newly transplanted evergreen tree shrubs before planting, and the amount of pruning should be properly pruned on the premise of maintaining the basic skeleton of the transplanted trees. Of course, the specific amount of pruning depends on the tree species, seasons, specifications, and the integrity of the soil ball.

In order to ensure the survival rate of transplanting evergreen trees and shrubs, it is advisable to control the pruning amount of the evergreen trees and shrubs in the range of 1max 4, 1pm 2 and 2pm 3. In particular, camphor and Duying should be trimmed heavily rather than lightly in order to achieve a survival rate of more than 95%.

When transplanting large trees or trees whose soil balls have been damaged, these wounds will accelerate the water loss of trees because they inevitably leave large wounds when cutting off the lateral roots of trees and pruning the lateral branches of the crown.

In this regard, the measures often taken are to apply wax or paint and medicament treatment to the wound, one is the wound tonic, which can prevent the loss of water and nutrients, help the wound to recover, and promote the wound healing; the second is the anti-rotting agent, which can inhibit the occurrence of rotten roots and create a good growth environment for tree roots, so as to improve the survival rate of trees; third, transpiration inhibitors can inhibit the evaporation of water in trees and improve the survival rate.

Transplanting of evergreen trees and shrubs

The transplanting of evergreen trees and shrubs is similar to that of deciduous trees and shrubs, but attention should be paid to "shallow planting in deep holes".

When digging the planting hole, the excavated soil (the shallow soil at 30 cm above the surface and the deep soil below 30 cm below the surface) should be placed on the edge of the hole respectively, so that the soil ball will be tamped while covering the soil after entering the hole. The diameter of the planting point must be 20cm to 30cm larger than the diameter of the soil ball, which is easy to operate, and the depth of the hole should be slightly shallower than the thickness of the soil ball. If you plant a larger size of evergreen trees, the thickness of the cushion at the bottom of the tree hole is also different, generally the bottom soil cushion is 20cm to 30cm.

When digging a hole, you should pay attention to the leveling of the bottom of the hole, the upper and lower caliber of the point should be generally large, and do not turn it into a pot bottom. When the earth ball enters the hole, you can first insert a small amount of soil into the lower part of the soil ball to make the tree upright and stable, and then cut the packaging material, paying attention to take out all the non-perishable materials, so as not to heat up the packaging in the process of decay and affect the growth of trees.

After the trees are positioned, they can be covered with soil, and the topsoil dug out during digging holes will be filled and compacted at the same time, and when the covered soil is slightly below the ground, it will stop covering. After watering, when the soil ball settles to the level of the ground, make a small ridge around the tree hole to form an irrigation Weir. Water the Weir again the next day until it is thoroughly watered. Then rake the soil flat and make it into the shape of steamed bread. Pay attention to moisture conservation and management within one month.
