About Hardiness Growing Zones in Iowa
If you are looking for the growing zones in Iowa, you will need to refer to the USDA plant hardiness zone map. The USDA hardiness map above, for Iowa growing zones, can help you determine what planting zone you live in.
You can find growing zones in Iowa by looking at the map above and locating the general area in which you live. Then you can compare the color of your planting zone to those found in the legend to the right of the Iowa plant zones map.
This map, which represents Iowa plant zones, is based on the 2012 revision to the USDA planting zones. This change was made due to the recent climate changes, resulting in warmer climate zones in some areas that were previously cooler.
You should take time to understand your Iowa growing zones so you can choose plants that will tolerate your winter region. By choosing plants matching your zone, or one lower, they will be better equipped to survive wintry conditions. Plants grown outside your zone, or in higher zones, will generally require additional protection or relocation indoors.
You can find plants appropriate for growing zones in Iowa at your local nursery. Reputable nurseries will sell landscaping plants that survive your area’s climate conditions. These plants will also be marked as hardy to a specific growing zone. Non-hardy plants should also be labeled as such.
