Choosing a place for azaleas
Azaleas belong to the wider rhododendron group and include both deciduous and evergreen plants. Most prefer an acidic, humus-rich soil that remains moist but does not become waterlogged. Light shade and shelter from drying winds are a sensible starting point. Test garden soil before planting; where it is alkaline, use a suitable container and peat-free ericaceous compost.
Planting, watering and mulching
Plant in spring or autumn, leaving room for the selected variety to reach its mature size. Water newly planted shrubs in dry spells, preferably using rainwater where available. A loose organic mulch helps retain moisture, but keep it clear of the main stems. Avoid deep planting, heavy feeding and standing water around the roots.
Pruning and potential problems
Most azaleas need only light pruning or removal of dead growth, ideally after flowering if shaping is necessary. Check discoloured foliage for possible pH or nutrient problems, and watch for vine weevil and root problems in poorly drained containers. Flower colour, height, hardiness and pruning needs vary by cultivar; do not apply a single rating to every azalea.
