What disease could be killing my azaleas?

Answer by  worker1961 (14)

Microscopic worms, called stunt nematodes, can cause damage to the feeder roots of azalea plants. This root damage makes the plant susceptible to destructive soilborne microogranisms and pathogens which restricts plant growth causing the plant to become stunted and yellow. Heavy infestations of this microscopic worm can eventually kill the plant.

If the underside of the leaves are silver and black this could be mites or lacebugs. If buds are starting out well then drying and dropping off the problem could be thrips or botrytis. Dropping blossoms could indicate a watering issue or a need for repotting. Bright yellow spots is a fungal disease called azalea rust, brown with white Pestalotia.
