Growth on Azalea Bark

Anonymous added on May 5, 2014 | Answered

Have a number of azaleas, most are doing great but a few have this pale blue-green, flaky looking growth on the bark, like you sometimes see on really old plants but these are fairly young. What is it and will it infect my other plants?
