Powdery mildew . Honeysuckles are susceptible to powdery mildew when they're too dry at the roots. They need a lot of watering, especially when they're planted at the base of a wall.
I would give it a bucket full of water three times a week, whether it rains or not, from now until the end of September.
Start doing the same again at the beginning of March right through to September every year and also in March give it a sprinkling of Fish Blood and Bone as directed on the pack.
