When to Start a Garden in North Carolina: Frost Dates and Planting Windows
What Are Frost Dates and Why Do They Matter?
Frost dates mark the average last frost in spring and the first frost in fall. Planting too early risks frost damage, while planting too late shortens the growing season.
| Region | Average Last Spring Frost | Average First Fall Frost | Growing Season Length (Days) |
|—————-|—————————|————————–|——————————|
| Coastal Plain | March 15 – March 31 | November 15 – December 1 | 240+ |
| Piedmont | April 1 – April 15 | October 15 – October 31 | 190-210 |
| Mountains | April 15 – April 30 | October 1 – October 15 | 150-180 |
Best Time to Start Seeds Indoors in North Carolina
Starting seeds indoors gives plants a head start before transplanting outdoors.
- Cool-season crops (lettuce, broccoli, cabbage): Start indoors 6-8 weeks before last frost date.
- Warm-season crops (tomatoes, peppers, eggplants): Start indoors 6-8 weeks before last frost date.
For example, in the Piedmont region with an average last frost around April 10, start tomato seeds indoors by late February to early March.
When to Transplant or Direct Sow Outside?
- Cool-season crops: Can be planted outdoors 2-4 weeks before last frost. These include peas, kale, spinach, and radishes.
- Warm-season crops: Plant outdoors after last frost when soil warms, usually mid-April to early May depending on region.
