What USDA Zones 5–6 do—and do not—tell you
These zones span average annual extreme minimum temperatures of roughly -20°F to 0°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
- Caps are well formed but margins have not flattened completely
- The cluster is firm, fresh, and free of discoloration
