Transplanting Time for crabapple Trees
As a traditional famous tree in the courtyard, crabapple trees are deeply loved by horticulture enthusiasts for their magnificent flowering. Mastering the scientific timing and methods of transplanting is the key to ensuring the survival of the plant. This article will systematically analyze the entire process of transplanting crabapple trees from seasonal selection to operational details.
I. The Golden Period for Transplanting crabapple Trees
1. The Best Spring Transplanting Period
In March-April, after the soil thaws and before crabapple trees start to sprout, it is the best period for transplanting. At this time, the ground temperature rises to 5-10°C, the root system recovers quickly, and with the nourishment of spring rain, the survival rate can be increased by 70%. Special attention should be paid to avoiding the late spring cold period, as the cold tolerance of newly transplanted trees will decrease by 30%.
2. The Second Best Choice in Autumn
Transplanting in October-November after the leaves fall is necessary, ensuring there are 30 days for root growth before the soil freezes. In the northern regions, it is recommended to move it forward to late September, while in the south, it can be postponed to mid-November. Transplanting during this period requires enhanced winter protection, with a 5cm thick layer of pine needles for insulation.
II. Core Techniques for Transplanting crabapple Trees
1. Scientific Seedling Lifting Standards
Water thoroughly 10 days before lifting the seedlings, and the diameter of the soil ball should be 6-8 times the diameter of the trunk. Use the three-side trenching method for digging, and apply a healing agent to the cut-off main root. For precious varieties, it is recommended to cut the roots one year in advance to promote the growth of fine roots.
2. Key Points for Reasonable Pruning
Adult trees should retain 3-5 main branches, with the tips cut by 1/3 of their length. Prune the crossing branches and diseased branches, with the cut 0.5cm away from the bud eye at a 45-degree angle. Large wounds should be coated with tree wound protectant to prevent bacterial infection.
3. Detailed Planting Procedures
The diameter of the planting hole should be 40cm larger than the soil ball, with a 10cm layer of decomposed organic fertilizer at the bottom. Fill the hole in layers and compact it, ensuring the root collar is 3-5cm above the ground. Water immediately after planting, and complete three thorough waterings within 7 days, with the use of root growth powder for better results.
By precisely grasping the transplanting season and following standardized operational procedures, the survival rate of transplanted crabapple trees can reach over 90%. It is recommended to use shade nets for seedling acclimatization and apply phosphorus-potassium fertilizer monthly for the first three months to promote root development. Following the plant's growth rhythm will allow you to witness the flourishing scenery of crabapple trees with abundant flowers and leaves year after year.
