The only tool you need for contorted hazelnut pruning is garden pruners. You also might want to have a pair of garden gloves handy.

How to Prune a Contorted Hazelnut

If you are wondering how to prune a contorted hazelnut, it isn’t very difficult. The first step in trimming corkscrew hazelnuts is to remove about a third of the plant’s oldest stems. You can do this each year. Remove these stems by pruning them back to their parent branches. You should also prune inward growing stems back to outward facing buds.

When the goal for pruning a corkscrew hazelnut is to shape it into a small tree, remove the lower lateral stems. Ideally, this trimming should be done the second year after planting. As time passes, remove any branches that do not contribute to your vision of the plant.

During contorted hazelnut pruning, always check for suckers at the base of the shrub. Remove these suckers to prevent them from competing with the parent plant for soil nutrients and water.
