To determine your growing zone, you can use the USDA Plant Hardiness Zone Map. This map allows gardeners and growers to determine which plants are most likely to thrive at a location. The map is based on average annual minimum winter temperatures, and it divides North America into 11 separate planting zones, each growing zone is 10°F warmer (or colder) in an average winter than the adjacent zone.

To find your growing zone, you can enter your 5-digit zip code on the USDA website. Alternatively, you can use other websites like Plants Express or LawnStarter to find your growing zone by entering your zip code. These websites use the same USDA Plant Hardiness Zone Map to determine your growing zone.

It is important to note that the USDA Plant Hardiness Zone Map is a reference for gardeners who want to know which plants will thrive in their area in winter. This applies to perennials, trees, and shrubs as well as the grass that covers your lawn.
