Planting calendar
Windows below are from NC State Extension, Eastern North Carolina Planting Calendar for Annual Vegetables, Fruits, and Herbs, retrieved 2026-10-10. Eastern, central, and western North Carolina are separate calendars. The publications do not define those regions by county. The eastern calendar says gardeners at the coast can plant up to two weeks earlier in the spring and two weeks later in the fall. That sentence is not turned into new dates. Half-month cells that carry the same mark are read as one run. A mark at both the start and the end of the year is one window that crosses New Year’s. Each region links to its own publication.
