Winterizing Palm Trees - USDA Growing Zone Map & Cold Hardy Palm Tree Chart
Brought to you by Cole Farms, Inc.

The chart above outlines the growing zones for the United States. These zones are based upon the mean low temperature of a region. The lower the low temperature the lower the zone number. The recommended zone for palm trees below is based upon an unprotected tree. Winterizing any tree will make it possible to jump up a zone fairly easily. More diligent efforts would have to be made to jump 2 levels.
