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 3 weeks for staggered harvest

How to know when to harvest

  • Tops of roots are visible at soil surface, about 3/4 inch diameter
  • Foliage is full and dark green
  • Gently brush soil away from top to check size
