Title: Wisteria
Post by: RDmom on April 07, 2013, 10:53 PM
I have 2 healthy Wisteria 12+ years old that have never bloomed.
I am trying to figure out why they have never produced blossoms and
what I can do now or during the growing season to encourage flowering
next spring.

Remove long tendrils as they suck energy from the short shoots where flower buds form.  Some say allow to become very pot bound (not hard  :)), and leave 3-5 buds when you prune shoots back.  They don't bloom off new growth, but off two year old+ stems.  These will have a slightly swollen appearance.  Just for fun, here's a link to a wisteria show I saw in Nara last year (

and another post about wisteria in Nara. (

They have a symbiotic relationship with Nitrogen affixing little buddies in their root system, so an abundance of nitrogen in your fertilization plan can be a problem.

Thank you. The pictures made me drool.
I live in the desert and have had to pot up all of my trees and still have to water daily from spring to late fall. My elms, maples, and a few others have to live on the covered patio where they get sun in the early morning or, depending on which end of the patio they are on, for a short period in the afternoon.
Do you have a suggestion for a good low nitrogen fertilizer?
Again thanks for you reply. I've missed being around bonsai people since I moved here 12 years ago.
