Poorly Honeysuckle

Planted in large trough at the back garden in very sheltered spot last year. It gets sun for part of the afternoon. Suffered badly from powdery mildew last year. Treated with spray but did not really recover. Cut right back last Autumn. Started growing really well this year with loads of new shoots. Sprayed preventative mildew spray 3 weeks ago. Now all the leaves closest to the fence are all yellowing and dying off and it does not look at all like its planning to make any flowers. Help!
