    I would just take a pair of pruning shears and trim away the azalea, branch by branch, from around the nandina. Trim away until just the stumps are left. Paint the fresh cuts on the azalea stumps with Round-up to finish off the root system.

    It sounds like an azalea stem borer. This article will help you:

    Unfortunately, it is most likely root rot. This article will explain more about it:

    Sooty mold or sooty canker can give leaves a burned look, but they normally do not manifest as spots, but rather as large areas that look to have been burned.

    Older azaleas are susceptible to a condition called leaf spot. It is caused by a fungus and happens after cold winters. Normally it clears up on its own, but you can treat the plants with a fungicide to help clear it up faster.
