What Are Plant Hardiness Zones?

Garden enthusiasts will tell you that plant hardiness zones are the secret to success. Even experienced gardeners sometimes need a refresher on the zone-specific habits of their plants. Browse the USDA Plant Hardiness Zone Map to gauge your average annual minimum temperature and improve your growing space’s hardiness zone.

Plant Hardiness Subzones

Zones are carved into subtler segments, marked by incremental shifts in the average annual minimum temperature. For instance, Zone 4a experiences average lows between -30°F and -25°F, contrasting sharply with the chillier Zone 4b, which falls within -25°F to -20°F.

It’s amazing how plants can thrive or, worse, wither away due to factors like temperature and precipitation. By selecting plants tailored to your specific zone, you’ll be investing in a sense of reliability and reduced stress. The last thing you want is for your carefully curated garden to fall victim to environmental conditions.

For a quick and easy way to determine your hardiness zone, head over to the USDA Plant Hardiness Zone Map and plug in your zip code. With your zone in hand, you can start exploring the vast array of plants that will thrive in your outdoor space.
