What USDA Zones 7–8 do—and do not—tell you
These zones span average annual extreme minimum temperatures of roughly 0°F to 20°F. That is useful climate context, but it does not determine your exact frost dates. Check a local forecast or county Extension calendar before planting tender crops.
How to know when to harvest
- The root shoulder has reached the expected mature width
- Foliage is healthy before hard stress or bolting
