Shaping a smaller climbing rose (Jazz) as a shrub
We have the rose 'Jazz' (Previously called 'That's Jazz' I believe). It is described variously as a 300cm or 200-300cm climbing rose. Due to circumstances it ended up a stand-alone shrub. Occassionally I struggle with it; this year because it grew quite a few branches on top with many flowers on the new growth of about 3 feet in length, and these branches start to weep heavily. Is there a method I can use? Or am I torturing the poor shrub? Its described height seems to make my quest a tantalising possibility.
