Re: heading back wisteria

Hello Susan,

Yes. your friend's wisteria will re-sprout.  However very often, not where you expect or want: either below the graft union if there is one, or from below ground.  If I were to do this, I'd try to leave one or two fairly long branches and just tie or brace them back while the new arbor is being built.  Then she'll have to be faithful to pull, cut off, or dig out those lower sprouts as they come in the next years.

Cathy R. (of this list) and I were just having a wisteria discussion concerning its roots lifting patio floors.  Perhaps she'll have additional advice for you.

Can anyone help me advise a friend about severely cutting back an old wisteria vine? It is at least 30 years old, with a large braid of a trunk. The arbor that it sprawls on needs to be replaced, so I am wondering if it is possible to head back the trunk at the height of the new arbor. Will the wisteria re-sprout out of the trunk? I know they are tough but will it accept this abuse?

 

Thanks for your help.
