What USDA Zones 11–13 do—and do not—tell you
These zones span average annual extreme minimum temperatures of roughly 40°F to 70°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
- Seed heads are dry and the grain resists a thumbnail
- Stalks have shifted from green to straw colored
