Blue Spot on Azaleas

highroller2 added on February 14, 2012 | Answered

Something is causing almost all of the foliage (leaves) to drop off the branches as if my azaleas are dying. I think I can see what I have been told is BLUE SPOT. What can I use to save my azaleas?

It sounds like it may be Cercospora Leaf Spot. It causes blue spots in some varieties of azalea (and red in others). The defoliation is unsightly, but will not kill the plant. To treat it, just spray the plant with a fungicide. You may want to repeat the treatment every few weeks until you are sure it is cleared up.
