My potted azalea has finished flowering, how should I look after it?
Keep your azalea in an unheated room, and in a light place during the winter.
The leaves will drop off if the room is too warm and dry.
If the soil appears to be dry give it a good watering, overhead spraying of the leaves will help to keep the plant turgid.
If the plant is pot bound repot it in spring using an ericaceous (lime free) potting compost.
Trim/prune plant lightly to maintain shape.
Stand the pot outside in partial shade during the summer, returning it indoors around the end of September.
