they're not fun when you're battling with them every year! we have tons of it overgrowing on one level in the back garden and on the roof of the garage!
Its a bloomin pain, i chop them down, put weed killer down, they grow back!!!!
As I write this I can see a stem dying to grow over the window
I gave up with the garden this year, nearly killed me last year
Hope what you took Fish has worked out for you, sorry I wasn't in at the time...had to go and get some surprises for my dd's b/day.
