Understanding Hardiness Zones

Arctic
-60°F to -40°F
Cold
-40°F to -20°F
Cool
-20°F to 0°F
Moderate
0°F to 20°F
Warm
20°F to 40°F
Tropical
40°F+
Zone Gardening Tips
Match Plants to Zone
Always check plant tags for hardiness zone ratings. Plants rated for your zone or lower will survive winter.
Consider Microclimates
South-facing walls, low spots, and protected areas create mini-zones that can be warmer or colder than your zone.
Push Boundaries Carefully
Growing one zone warmer is often possible with proper protection, placement, and winter mulching.
Native Plants Excel
Native species are perfectly adapted to your exact climate, soil, and growing conditions.
Know Your Frost Dates
First and last frost dates matter as much as hardiness zone for annuals and vegetable gardening.
Test Before Investing
Try one plant of a borderline-hardy species before buying multiples. Some years are harsher than others.
