The year-round bloom _may_ also be weakening your tree. They do need a
rest from the energy expended in creating buds. And azalea also need a
short period of cold (or at least very cool) dormancy.

I agree with all Jim said ,I have few Azaleas since
many years and are kept as Jim says.. one more thing , they
need acidic soil so sometimes to time some iron will help
Azaleas belong Rhododendrums family and withstand cold very
well

keep them in mid sun only when are flowering
