2. Mechanical damage should be minimized as much as possible. Pruning of large branches should be completed in one go during the winter and spring dormant period. Apply whitewash to the branches and trunk to prevent frost damage and sunscald. Eliminate branch and trunk pests in a timely manner, and correctly master the types and concentrations of sprays.
