  • 50% probability frost normals are estimates, not frost-safe planting guarantees.
  • These are 1991–2020 normals, not live weather or current soil temperatures.
  • Local elevation, exposure and soil readiness can change planting decisions.
  • Harvest windows use crop maturity ranges and do not guarantee a fall harvest.
