Hedges of Escallonia can be trimmed or pruned immediately after flowering. This will produce fresh young growth which will harden up and ripen before the winter.
The Mount Etna Broom (Genista aetnensis) – one of the best summer shrubs, should be coming into bloom. Make sure it is well staked if necessary and does not “rock” on its roots.
Permanent plants in containers should be regularly fed to produce flowers with a high potash fertiliser but their foliage and growth might also need a boost with a high nitrogen feed.
