What USDA Zones 9–10 do—and do not—tell you
These zones span average annual extreme minimum temperatures of roughly 20°F to 40°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 is fully colored with slight give when gently pressed
- Bottom of fruit (blossom end) turns from green to full color
- Fruit may crack in heavy rain if left too long
