What colour were the flowers, white or yellow? If they were white, this plant should be thinned out after flowering, so around June. Cutting back hard at any time usually means you'll get no flowers at all the following year, which is why they suggest you 'thin out'. If it had yellow flowers in early spring and the stems remain green all winter, that one can be cut back hard, immediately after flowering has finished.

Thanks Bamboo. The flowers are tiny white ones.
So when it dies back this year don't do anything with it ? Then what do I need to do in June, not quite sure what to "thin out" means. Sorry I am a bit of a novice.

So probably J. officinale then - that's why it hasn't been flowering, you've been cutting it back every year, lol! Thinning out just means removing flowered shoots, maybe taking out a quarter of stems at the base as well. Be aware that this climber gets 35 feet by 12 feet eventually, and it flowers best if its never pruned at all, but leaving two thirds of the growth untouched each year should mean you get flowers.

Thanks Bamboo, OK I will have to prune at some point. so leave as it is now, don't trim back, then in June remove 25% of the stems at the base. Then in 2015 I might get some flowers lol. Might think about replacing it then :)

You should get some flowers next year, as you haven't done a heavy cutback this year. Fingers crossed!
