The results of pruning wisteria and clematis abound in May.
Regular pruning of clematis encourages strong growth and flowering and keeps the growth in check. If left unpruned, clematis can turn into a mass of tangled stems with bare base and flowers well above eye level.
Wisteria needs regular pruning to keep the growth and size under control, but it will also improve the flowering display. Prune twice a year: in Jan-Feb and Jul-Aug
