Honeysuckle

Jocelyn A

I have a 3yr old Honeysuckle in a pot in a shadey back yard. Having fed and watered it well this year, it flowered beautifully. I think it got too dry in the warmer weather as I was worried about over-watering. Now the powdery mildew has taken hold of it and although the plant has been fighting back with new growth and berries, the leaves have been dropping now for about 3 weeks...so do I prune it back now, leave it to struggle through winter or what?? It's looking a bit sad now. Thanks for any thoughts
