It's a little hard to tell by the close-up, but it appears to have mildew. Powdery mildew, which starts in dry weather, is easily controlled by regular spraying with a soap and baking soda mixture, or with diluted milk. Downy mildew, which appears in warm, moist weather, usually needs a fungicide specifically for it. Also, what have you been feeding it with?

Mine is exactly the same and I've decided to cut it to the ground this Autumn as it's been 'poor' for a few years...and always gets mildew! Comments?

On the Hall's Honeysuckle, it seems to get mildew worse in the shade, so I would double check the exposure. In the UK, I would expect a south or soutwest exposure, with no shade trees or large shrubs surrounding, to be essential.

Thanks for the comments, Its on a south facing wall, so gets plenty of sunshine, Not sure what i feed it with as i have had it for a few years and isnt in the original box, they are turquoise colour granules. I usually just cut about a third of the stems to ground level, but I think i will give it a drastic prune this year, is it okay to cut the main stem to ground level?

It should come right up again, but it may decide not to bloom. Do you mean that all that it has had in the way of food was what you had in the original container?

Yes, as the feed was a few years old it may not have been adequate do u think? Also are the roots supposed to be in the shade?

Even timed release feeds rarely last longer than 9 months, though their empty remains can stay visible for far longer, sometimes fooling even the experts! It sounds like it is long overdue for another dose. Be sure to read the label for frequency of application, but remember that it won't help during the winter, so a short term liquid food may be best to apply now, to pump up its health before fall.
