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
- Stalks are 8-12 inches tall
- Leaves are glossy and vibrantly colored
- Outer leaves are mature enough to snap cleanly
