azalea bushes seem infected or dying

Question

Most of my azalea bushes and some other flowering bushes I don’t know the name of are drying up, the bark looks black, leaves are falling off and the flowers barely came in. These plants are in a new home I purchased so I don’t know their history other than the first two years they all seemed healthy. This year they have all taken a turn. No images at this time.

Answer 1

Could it possibly be azalea bark scale? See: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/azalea-bark-scale.htm
