Regular pruning after flowering results in a lovely bushy tree.
Timing: Annually; after flowering for those that flower on the previous year's growth, or in late winter or early spring for those flowering on the current year's growth.
Pruning: Shorten sideshoots to within two to four buds of the permanent framework of branches. Remove shoots growing towards the wall.
Pruning at the wrong time of year may result in a poor display the following flowering season. Plants should recover and flower again fine in their second flowering season after pruning, so no long-term damage will have been done. Renovated plants that have been hard-pruned may take longer to re-start flowering.
