Part 2 - Powdered Mildew on Lonicera

Looks like it. They seem very susceptible.

Further to my answer on part one, I think this has gone too far for the milk treatment. It looks saveable for future years though so go to a local, decent, garden centre or large nursery and get a fungicide or, if you are able to use it safely, get some Bordeaux mixture on-line and spray according to the instructions. Good luck.

Oh dear - second year running with this problem and still no flowers because of it. Do you think it could be the location? Off to GC now - Thanks for the help.

More likely all this rain. Spray it with a fungicide.
