The season of transplanting and selecting the tree
The season of transplanting
If the cherry bay is transplanted too early, the temperature is high and the evaporation is great. The root of the tree may be hurt. The capacity of absorbing water is weakened. The tree will defoliate or even wither. As the big cherry bays are mostly transplanted from the southern area, if they are transplanted too late, there will be no transition period for them to be seasoned with the weather in the north. The tree is easy to be winterkilled. Even if the tree survives, there will be few branches and leaves. Many experiences prove that it is the best time to transplant the big cherry bays in mid November in Zhengzhou area. At that time, the air temperature begins to fall, there is less evaporation, the ground temperature is high, and the cut of the hurt root heals rapidly. At the same time, some capillary root will grow to make up for the deficiency of nutrient-absorbing capacity. The cherry tree can live through the winter successfully.
Selecting the tree
Choose the tree that is plump, has flourishing branches and leaves, has no plant disease and insect pests, and is easy to dig and transport.
Preparation before transplanting
Dig planting pit
The planting pit should be dug one week before transplanting. The diameter of the pre-dug pit should be 1m longer than the package diameter of the transplanted tree (to make it easy for the workers to work in the pit), and the height of the pit is the same as that of the package. Separate the surface soil and subsoil dug out of the pit. Spread out the soil to dry it in the sun. Clear the bricks and tiles in the soil. Mix ferrous sulphate into the soil at the ratio of 10:1 (10 for soil). This increases the acidity of the soil and sanitizes it. The fertility is also increased.
Pruning is a key factor to the survival of transplanted cherry bay. The cherry bay is not good at sprouting. Therefore trunk cutting and lopping is not advisable. Only the leaves can be pruned. Cut off the leaves with scissor and reserve the leafstalks to protect the axilliary bud. Reserve one-third of the leaves on the tree. This can reduce evaporation and preserve the beautiful shape of the crown.
Lifting and transporting
Hard packaging is best for transplanting cherry bay. The cherry bay that is about to be transplanted should be watered thoroughly one week in advance so that its root can absorb enough water. This way, the earth ball will be sphered and not falloff. The diameter of the earth ball should be 6-8 times the crown diameter at the height of 1m above ground; the height of the earth ball is 70% of its diameter. Itll be better to dig bigger if possible. When the tree is dug, remove the surface soil on the basis of the tree trunk. The shape of the earth ball should be trapeziform cube in required diameter. The lower diameter is 1/3 the upper diameter. The diameter of the earth ball should be 5-10cm longer than the template (so as to tighten the earth ball with the template). Get the template, threading (made of steel fiber) and iron wire ready to package the earth ball in time after it is dug. If some big roots need to be cut off, cut it with handsaw, dont chop with other device. The root transect should be treated with a mixture paste of sulfur powder and ABT rootager at the ratio of 3:2. When the earth ball is dug, buckle the template immediately and tighten it with threading. Wrap the tree trunk with grass ropes and lift the tree into the vehicle.
When the cherry bay is lifted onto the vehicle, it needs to be set erectly. Put some original soil (the soil from which the earth ball is dug) around the earth ball and pack it with wovenbag. Wrap the tree crown with plastic film to prevent it from swinging in the process of transportation.
Planting and management of later stage
Before the tree is planted, the pre-dug pit should be backfilled with the original soil for 10-15cm. Cherry bay is not endurable to waterlogging, so that the tree should be planted 10-15cm higher than the original ground. Lift the tree down to the pit, set it at its original exposure. Then put a plastic tube at each of the four corners of the pit. This will increase the air permeability of the root when the pit is filled. Remove the template in proper order and backfill the pit to 1/3 the height of the earth ball. Fill the original soil closely by the earth ball. Tramp solid every layer of soil when it is filled to prevent the earth ball from splitting. When the pit is wholly filled, set a cofferdam and a brace, and water it thoroughly.
Later stage management
Firstly, water the tree thoroughly 3-4 days after the tree is watered for the first time. Secondly, when the water is dried in the shade, surround the base of the tree with the remaining soil around the pit to form a heap, which is higher in center and lower in the outside. This will prevent the cherry bay from being drowned by seeper. Thirdly, water the tree thoroughly in the next spring. Fourthly, spray the leaves and branches with a mixed liquid of KDP and bactericide when the average temperature is about 20. This is to apply the topsoil dressing on the leaves and kill the viruses.
