If you think of an archetypal country cottage, it is thatched, and the walls are covered with wisteria. But keeping this magnificent plant in flower is no mean feat, it needs to be pruned regularly and correctly in order to keep it in good flowering order.Mr DigwellEssentially, pruning wisteria is a three fold job. First you are to remove any dead, damaged or rubbing wood – that is wood rubbing against another branch. Also remove wood growing towards the wall – the plant should be trained on a series of wires off the wall.

Secondly, cut back side shoots down to two buds, to keep the plant from rambling out of control. Both these steps can be done in January / February. Take away any cuttings.

In August, after flowering, you should reduce the size of the long whip growth by half, increasing air circulation and will encourage flowering next year.
