Our Wisteria (25 years old and old friend) isclimbing in and has pushed a double glazed window off its hinges!! It will no longer shut properly . Can I cut the plant back to the main stem or will this kill it? It holds fond memories so I don't want to take it right out.
Cut it right back or it will attck you in your sleep! Quite thuggish these so you are unlikely to kill it.
I saw one once that had pulled a cast iron verandah off a house.
cut it back hard and keep it well pruned, and it will flower its socks off.
THANKYOU. You've put my mind at rest.
I'll introduce it to my saw!
Wisteria need to kept under control and will flower better if they are properly pruned - lots of info and an explanatory video here http://apps.rhs.org.uk/advicesearch/Profile.aspx?pid=242
