Pruning group
Pruning group 1
Suitable for: Deciduous and evergreen trees, and some deciduous shrubs.
Pruning: Minimal pruning required. Prune wayward or crossing branches to maintain a healthy framework.
When: When dormant in the late winter/early spring. Some in the summer/autumn to prevent bleeding of sap.
Pruning group 8
Suitable for: Wall trained shrubs and less vigorous climbers.
Action: For climbers 'spur prune' by cutting back 3-4 buds of the permanent framework. For wall trained shrubs cut back flowered shoots to within 2-4 buds of permanent framework.
When: Annually after flowers if on previous year's growth, or in late Winter or Spring if on current year's growth.
