Non Flowering Honeysuckle

Thanks for your help with another problem I had.
My friend has asked me to ask you if you have any idea with his problem.
See below:-

Please can any one help I have two Honeysuckle plants approx four years old, my problem is at the start of each year they seem to put on lots of new growth then about his time of year start to drop their leaves and produce little or no flowers at all.
They have been like this for quite a while now. I have tried severe puning and again at the start of the year all looks promising, lots of new strong growth then nothing. Any ideas would be most welcome.

Many thanks.

 

Basically, Gaz, he should stop pruning and start feeding. Preferably with tomato fertiliser.:thumb:
