Our Hardiness Zone Map Gets a Refresh

The Arbor Day Foundation distributes millions of trees every year, so it’s important that we have an accurate hardiness zone map. This map separates the country into ten different temperature zones to help people select the right trees to plant where they live. Knowing this information helps us—and you—ensure the trees you receive have the best chance of thriving. It’s one of the important tools in any tree planter’s arsenal.

Hardiness-Zone-MapBecause of this, we gave ours an update. Take a moment to check out the Arbor Day Foundation’s new 2015 Hardiness Zone Map, based upon data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

We like to revise the map every 10 years or so to keep up with any temperature shifts that may have occurred. While not many areas changed with this update, people living in the  northeast or along the Ohio River Valley may be in a new zone.

Not sure what hardiness zone you’re in? We have a simple hardiness zone lookup tool to help you figure it out.
