Understanding USDA Hardiness Zones and how Utah is Different

USDA Hardiness Zones are a standard used by gardeners and growers to determine which plants are most likely to thrive at a specific location. The zones are based on the average annual minimum winter temperature, divided into 10-degree Fahrenheit zones.

Knowing your USDA zone is important because:

• It helps you choose plants that will survive in your area's climate.
• It guides you in determining the best planting times for your region.
• It assists in making informed decisions about plant care and protection.

By filtering plants based on your USDA zone, you can focus on varieties that have a high likelihood of success in your specific region, saving time and resources.

We take the USDA Zone with a grain of salt as it's not completely accurate for Utah. We actually subtract 1 from the zone number from the USDA as we find that's a better indicator of survivability. If you enter your USDA supplied zone number here, we'll do the math for you. Of course, you can override our suggestion in the USDA Zone selection box.
