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.

Succession planting: Plant every 2-3 weeks for continuous harvest

How to know when to harvest

  • Pods snap cleanly when bent
  • Beans inside are still small — you shouldn't see pronounced bumps
  • Pods are firm and about pencil-thickness
  • Over-mature beans are tough and stringy
