Before plastic surgery, a solid scaffold should be set up. Scaffolding styles vary according to different design requirements, such as square, rectangle, circle, polygon and compound shape.
Then plant the seedlings next to the shed column, generally each shed species 1 ~ 2 plants.
After planting, select strong branches as the trunk, select 2 ~ 3 main vines on the trunk, and then prune.
In the second year, the main vine was fixed on the scaffolding column manually, and then induced to the top of the scaffolding in the same year or the third year. Leave 2 ~ 3 secondary branches for each main vine, and cut off several robust buds from the main vine to cultivate secondary main vines.
Then, the original main vine is also cut short to promote the occurrence of lateral vines and the auxiliary branches at the base become thinner.
After 3 ~ 4 years of cultivation, most of the branches at the top of the trellis are covered to form the trellis form.
