Usda Planting Zone Map 2024. Here is how you can use the new usda zone map for your garden and how to know, if in the new version, your hardiness zone has changed. The new hardiness zone map released this year has been created using gis (geographic information system) to examine hardiness zones at a much finer scale than earlier maps.
There’s a good chance your zone shifted when the usda updated its plant hardiness map in 2023. The plant hardiness zones detailed in the new map define 13 distinct zones across the us and its territories.
