First Freeze in Iowa

This article was published originally on 9/30/2009

 A common question from home gardeners is when they can expect the first freeze of the fall to occur. Below is a map from the Iowa Department of Agriculture and Land Stewardship that shows the average date of first freeze falls between September 30 and October 15, earlier in the northwest and later in the southeast part of the state. You can also view the map online at the National Weather Service - Des Moines web site.
