It's time to: December
Gazania, euphorbia and pigface are three summer stunners that stand up to hot weather.
Azaleas need a trim after flowering to promote compact, disease-free growth. Remove tall, irregular, sucker-like growth that can cause the shrub to become leggy.
Cut back may bush (spiraea), removing the oldest canes at ground level to encourage arching waterfalls of new growth.
Hydrangea and agapanthus give a cool look to the Christmas table. To make hydrangea last longer, pick early in the morning and submerge the flower heads in water for an hour before draining and arranging.
How are the hoses? Fittings need replacing? When not in use roll the hose into a neat coil to avoid trip hazards and preserve the hose. Retractable hoses make the job easier.
Divide and repot late-flowering cymbidium orchids.
Keep an eye out for lacebug on azaleas, identified by the silver cast of infected leaves. Insects peak in summer: try a Confidor tablet or Richgro Bug Killa granules beneath azaleas to control them.
In summer choose tube stock or the smallest pot-size possible, to help establish root systems over summer.
The huge and heavy heads of dahlias can break the fragile stems so offer support.
Mulch the garden before the summer scorchers arrive.
