When to plant European Hazelnut
NC State Extension describes European hazelnut as a large suckering deciduous shrub grown for cobnuts; it produces suckers that may need pruning. It gives no planting date; set out dormant bare-root stock in early spring while the soil is workable.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
