The first year: planting 1 year cuttings with a height of 30-50 cm, then re-cutting the stems of the seedlings, airing for 20 cm, and cutting off 4-5 full buds, which can grow into 4-5 basic branches with a height of more than 50 cm in that year.
The second year: select 3~4 basic branches in different directions as the main branches, lightly cut short, leave 2/3 branches, leave lateral buds at the cut, and cut the rest branches from the base.
The third year: lightly cut the selected main branches and extended branches, each main branch selects 2~3 lateral branches, and lightly cut the short branches to form a happy crown. Cut off the branches below 40 cm from the ground from the base of the main branch. Pay attention to remove sprouted branches in time.
The fourth year: continue to cut short the extension branches of main branches and side branches at all levels, pay attention to cutting branches and sprouting branches below 40 cm, and continue to expand the crown. At this point, the crown was basically formed.
