I meant to put up support wires for my jasmine last year but I didn't and it's now a real tangled mess. What can I do to get it back to a state where I can it on some support? Should I just cut it all down and start training the new vines? Or try to untangle each vine and then thread them onto wires?
Also, some vines have lots of flowers on but others have none at all and look quite different to the flowering ones. I thought these were sucker roots and started lopping them off but I Googled and now think they may be next year's flowering vines - oops! Is there a way to tell what's a sucker root and what's next year's flowering vine?
