The term "growzone" refers to the USDA Plant Hardiness Zone Map, which is a standard by which gardeners and growers can determine the appropriate plants for their local climate based on the average annual extreme minimum winter temperature. The map is divided into zones from 1 to 13, with each zone reflecting the plants' survival capabilities in the varying climates
. The USDA Plant Hardiness Zone Map is based on the average annual extreme minimum winter temperature, displayed as 10-degree F zones and 5-degree F half zones
. To find your growing zone, you can:
- Visit the USDA Plant Hardiness Zone Map website
- Enter your zip code in the Quick Zip Code Search box on the map
- Click anywhere on the map to view the corresponding interactive map
Gardeners should also consider microclimates, which are fine-scale climate variations within a general zone, as they can significantly impact plant survival
. Factors such as wind, soil types, moisture, humidity, pollution, and sunshine also influence plant survival, so it's essential to consider these aspects when selecting plants for your garden
