Growing
Azaleas are available for shady spots as well as for sunny
positions. All Azaleas need an acid soil and will not grow in
alkaline soil. They have a shallow root system and therefore
need to be kept cool, moist and shaded especially in warmer,
dryer regions. The soil around them should not be disturbed,
instead a surface mulch of humus, leaf mould or well rotted
compost that is maintained all year will assure success. Avoid
strong manure or lime.
The evergreen types will grow in almost any climate except
the tropics and the deciduous types prefer cooler climates.
Pests
There are a number of things that can go wrong with Azaleas,
they are:
Insects like Aphids on young growth, Mites and Thrips can make
the foliage look yellow, dry and unsightly if they infest your
plants, as well as Sooty mould that sometimes follows the invasion
of sapsuckers. Spaying with Confidor, Mavrik or similar will
correct this problem.
Leaf
Gall (a thickening of leaves and flowers) and Petal
blight (discolouring and disintegrating disease of the flowers)
are corrected and usually avoided by removing spent or diseased
flowers and by avoiding to overwater.
