I am having a problem with Mealy bugs in all of my customers viburnums after I trim them. Each account that I have picked up has had over grown shrubs and needed heavy shearing and it seems that this opens the plants up to instant infestation. Is this common with viburnum? Should I shear them again or do like I have done and just selectively prune until the PCO can treat the infestation? It really worries me that I will do more harm than good if I go shearing again. Could it be the Fluid Film I use calling the bugs in? I use it religiously, I just don't hear other LCO's talking about pests in their customers ornamentals. Any advice as to how to proceed would be truly helpful. These bugs are driving me crazy!!
