The pruning of flowers should be based on light pruning, and the principle is that natural trees are tall and strong, with dense branches and many symmetrical side branches. When pruning cherry blossoms, we should pay attention to the following questions:

First, shaping and pruning before flowering, properly thinning out overgrown branches, cutting off inner cavity branches, upright branches, delicate branches and pests and diseases. After pruning, apply fertilizer once.

Second: don't hurt the bark when pruning during the growth period to prevent wound infection. Because cherry blossom wounds heal slowly, they should be disinfected with drugs in time after pruning to prevent bacteria from invading after rain, leading to rot. Treatment after pruning: apply disinfectant such as 5 degree stone sulfur mixture or ink to the wound, and the effect is good.

Third: pruning after flowering should be carried out in the order of "from stem to tip, from inside to outside" First, observe the overall shape of the cherry blossom crown, then gradually trim the stems of the main branches from the inside out, and restrain or cut off the long branches, inner branches, combined branches, dead branches and diseased branches, paying attention to maintaining the symmetry and integrity of the crown.
