Identifying and Removing Reverted Stems on Harry Lauder's Walking Stick

Managing Reversion in Corylus avellana 'Contorta'

Harry Lauder's walking stick (corkscrew hazel) occasionally produces straight, vigorous stems—reversions to the species' normal growth. These differ in color, twist, and leaf size. They must be removed to preserve the plant's ornamental form.

When and How to Prune

• Best time: dormant season (late winter to early spring) to avoid sap bleeding.
• Cut reverted stems flush with the main branch.
• Monitor annually; revertants grow faster and will dominate if left.

To thicken growth on a sparse side, prune that side lightly in early spring and apply a balanced liquid fertilizer.
