Got a couple of calls from customers with Gumbo Limbo trees in decline. Showed up, trees and leaves covered in sooty mold. The leaves had the classic spiral egg pattern of the fly. Remarkably the nearby Crotons, Corn Stalk & Bougainvilleas were covered with the soot and appeared to be infested although not as heavily as the Gumbo Limbo. We pulled out the pressure cleaner and injected Dawn soap into the reduced pressure flow to clean as much soot from the trees and plants as possible. Next we applied topical and systemic drench to the foliage followed by a systemic bark drench; Safari has a formula for bark drenches. We'll see what the trees look like in a month. Curious to know if I should do a basal soil fertilizer injection or let the tree recover and then fertilize.
