February is the time to prune Wisteria (properly called Wistaria after the American Caspar Wistar 1761 - 1818). Having already, at the end of last June, pruned the young shoots (the laterals) to within five eyes of their point of origin now is the time to cut back again to about three buds. This creates the spur from which the best bloom is borne.

If this year you decide to buy a new Wisteria MEFIEZ-VOUS, and I speak from experience, because a lot of plants sold, especially in the super markets, are produced from seed and there is no guarantee that they will flower. So choose a plant that is in flower. We had one that, after three years, was so vigorous that it covered the whole front of the house but produced only one flower stem.

I found a very informative site when I 'googled' wisteria. Its the Ohio State University which has a wealth of information on the Fact Sheets which includes growing Wisteria. Go to http://ohioline.osu.edu/hyg-fact should take you to the Fact Sheet, but there are hundreds of fact sheets so you will enjoy looking around hopefully. If you have a problem get back to me, I have two Wisteria and I put them in last year and so far just leaves. Ever hopeful.
