If it is regularly watered and fed every two weeks, the spectacular display can last right through from June until the first frosts. Hedges Regularly trim hedges of Lonicera nitida and privet. Chrysanthemums Encourage chrysanthemum shoots to branch out and carry more blooms by pinching out shoot tips from June to early July. This technique is called stopping.
Cuttings Take cuttings from non-flowering shoots on many shrubs and climbers.
Flag iris Cut down the stems of bearded iris plants once the blooms have faded. It is also worth lifting and dividing congested clumps. Pruning perennials Immediately prune away faded flowers on lupins, delphiniums and other perennials. In some instances, early pruning can encourage a second flush of flowers late in the season. Cut the flower-spike down to just above a new shoot or leaf and give each plant a generous liquid feed to encourage fresh growth.
