Pruning:
For tree and deciduous shrub species: remove crossing shoots, annually, in late winter or early spring, to maintain a healthy framework. For evergreen shrubs: annually, in mid to late spring, trim shoots that are ruining symmetry. Deadhead if necessary. For wall-trained species: cut flowered shoots back close to the permanent frame, leaving about 2-4 buds. Might also want to trim shoots that are growing outwards or into the wall.
