The hedge is Eugenia Myrtifolia. Planted a year ago. The leaves started curdling a few months ago now some leaves are covered with this sticky black dust. The ones that got the black stuff earlier are starting to lose leaves. Only one section of the hedge is getting this but afraid it will spread. The areas that are infected are even discoloring the retaining wall beneath it making it look like it's constantly wet. TIA.
