Cut off too dense branches, dead branches and pest branches etc.
When thinning branches the stubs can not be left too long, generally should cut begin from the branching point, cutting with an inclination angle of 45 °, the incision should be kept smooth. Weak branches should be cut heavily while heavy branches should be cut lightly, 4-6 buds may be remained on each branch, the rest be cut off partly.
