On plant Wisteria japonica



HI Matt welcome to goy .Typically Wisteria pruned twice a year summer pruning after flowering finished(if lucky enough to have some) and winter prune.
In summer cut back those long whispy tendrils to about a finger length from main stem.In winter they can be given a hard prune if required.branches that have grown to desired length can be stopped by pruning ends Ideally Wisteria should have one main trunk with branches faning off this.If plant neglected or badly pruned now (winter) is time to remove excess basal growth.Wisteria should flower before leaves appear if flowers and leaves appear together sign of missed or incorrect pruning.
