A frost date is the average date of the last light freeze in spring or the first light freeze in fall. The classification of freeze temperatures is based on their effect on plants: Light freeze: 29° to 32°F (-1.7° to 0°C)—tender plants are killed. Moderate freeze: 25° to 28°F (-3.9° to -2.2°C)—widely destructive to most vegetation. Severe freeze: 24°F (-4.4°C) and colder—heavy damage to most garden plants.
Your first frost date is the most important date in your gardening calendar — and it's different for every region. This map shows average first frost dates across every US zone, from Miami's frost-free winters to Minneapolis seeing frost as early as mid-October. Find your zone, plan 2-4 weeks ahead, and save this every autumn. #FrostDate #FirstFrost #FallGardening #GardenCalendar #GardenZones #USDAZones #AutumnGarden #GardenTips #FallGarden
