What USDA Zones 1–4 do—and do not—tell you
These zones span average annual extreme minimum temperatures of roughly -60°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
- Fruit has its mature color, aroma, and a slight give
- Harvest timing matches the plant’s local season
