I have a honeysuckle which is very old, at least 20years I guess. It was covered in greenfly last year, I cut it well back and this year it looked pretty healthy, but now it is absolutely infested with greenfly again. I have never seen anything like it, can't think how it would be possible to get rid of them. Have I to get rid of it, which seems a shame in view of it's age. It is scrambling over an arbour so is difficult to reach. Any suggestions welcome. Thank you.
