The fluffy bits on the branches are most likely a result of a sap sucking insect known as Pulvinaria regalis. Some of the symptoms you describe also infer another bug called Pulvinaria hydrangeae. It is difficult to make a diagnosis with the limited information but, the principles of dealing with any of these wooly bug infections would be consistent. Deal with it if the plant is suffering with symptoms such as yellowing of the leaves. Because the adults are protected within wooly, waxy cocoons an oil based chemical insecticide should be used to control the pests in late summer when the juvenile larvae are actively feeding on the leaves. Please consult your local garden centre for a recommended proprietory spray.
