My neighbor's yard has hemlocks which have been dying for several years from woolly hemlock disease. About a month ago, I started seeing little white puffs (which have identified as woolly adelgids or woolly aphids) on my 16 Japanese maples. They have started looking very droopy with branches dying. The white puffs have also attacked my hollies (2 lost already), rhododendrons, and vine hydrangeas. Has anyone had experience dealing with these pests on Japanese maples? I have sprayed with generic insecticide/fungicide, insecticidal soap, and am waiting for a delivery of Imidacloprid granules for systemic control. My garden is being destroyed! Pictures of the white puffs are on leaves of a vine hydrangea. Any advice would be appreciated.
