Beautiful plant @ctrl-alt-nwo! Azaleas can give months of flowering  pleasure from winter to summer, but as with most plants, the best results require a little bit of attention. Watering should be done on demand and the plants kept moist, but be careful not to overdo it, especially in autumn and winter as azaleas need less water as the weather cools. Never water over the buds or flowers as this can cause fungal problems that result in a shorter flowering at best, and no flowering at worst.

Although Autumn conditions are not as conducive to "petal blight" as are the warm days of late Spring, it may be necessary to use Zayleton to control these problems if they occur at any time. Generally though, if overhead watering and torrential rain are avoided (Good luck with the latter), and dead flowers are picked off from time to time (put them in the bin not the garden), there is nothing to stop a wonderful display for many spring weeks, providing conditions remain fine.

As far as fertilising of Azaleas (and for that matter most plants) is concerned, monthly applications of Harvest or a Fertiliser for acid loving plants, as well as a measure of Osmocote, Organic Life or Cow manure every three or four months, should be all that's required to keep your plant in good shape. Remember not to use granular chemical fertilisers on azaleas in Autumn and Winter as you may destroy the Spring flowers. "Azalea & Camellia food" can be used after flowering to encourage new growth, but only sparingly on established plants in the ground, and never on plants in pots!
