Growing conditions in North Carolina change a great deal between the coast and the mountains. NC State Extension publishes separate planting calendars for eastern, central, and western North Carolina, and GardenSproutly presents all three side by side so you can see how timing shifts across the state.[1],[2],[3]
USDA hardiness zones are based on the average annual extreme minimum winter temperature. That makes them useful for choosing perennial plants, but a zone does not tell you when spring frosts end or how long your growing season lasts. Our vegetable calendars use regional Extension planting dates and station freeze records instead.[4],[5]
