it’s worthwhile bearing in mind that it is good practice with all trees and shrubs to cut back or cut out the weakest shoots, and to avoid cutting the strongest shoots hard. You will remember that hard pruning results in strong shoot production and not necessarily more flowers. The one thing that can be said about cutting out strong shoots of bougainvillea, for instance, is that they will provide good wood for converting into cuttings.
