When to plant American Hazelnut
NC State Extension describes American hazelnut as a suckering deciduous shrub that is not self-fertile, so plant in multiples for cross-pollination. No planting date is given, so set out dormant plants in early spring; nuts are typically produced on plants 2 to 3 years old and older, ripening in fall.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
