About Plant Hardiness Zones

The USDA Plant Hardiness Zone Map divides North America into 13 zones based on average annual minimum winter temperatures. Each zone represents a 10-degree Fahrenheit difference, helping gardeners select plants that will survive winter in their location.

Why Frost Dates Matter

Your last spring frost and first fall frost dates define your growing season. Tender vegetables like tomatoes and peppers can't go outdoors until after the last frost. The dates shown are historical averages - always monitor local forecasts.

Quick Zone Guide

• Zones 3-4: Northern states - short season, cold-hardy plants
• Zones 5-6: Central states - most vegetables thrive
• Zones 7-8: Southern states - extended growing season
• Zones 9-10: Deep South/California - year-round growing
