You can find your Idaho hardiness planting zone by looking at the map above and locating where you live. Note the color of the growing zone in Idaho where your town is located, and then compare that color to the legend to the right.
This Idaho growing zones map is based on the 2023 updated version of the USDA planting zones map. This change was made to the hardiness zone map due to the increasingly warm climate that has occurred over the past few decades due to climate change
The reason you should take time to understand your Idaho hardiness planting zone is because you should be selecting plants for your garden that will survive the winter in your area. By choosing plants that either match your zone or will survive in a lower zone, the plants you choose will have better chances to survive the conditions in your area.
If you choose to grow plants that are suitable for a higher zone, you will need to provide extra protection, or even bring these plants indoors for the winter.
Local nurseries will carry plants that will survive in your area. These plants will be clearly marked with the zone that they are meant for.
