Information About the Michigan USDA Planting Zone Map

This Michigan planting map, devised by the USDA, divides growing zones into 10-degree F. increments according to average winter low temperatures over a 30-year period. A new map for 2012 was recently released which indicates warmer average winter temperatures for many areas. This information is useful to both novice and experienced gardeners.

To locate your planting zone on the map, you can click to enlarge the map and find your general area. The Michigan plant map includes zones of cooler areas like 4a, 4b, 5a and 5b. There are also warmer pockets in the state that include zones 6a and 6b.

Understanding which growing zone you reside in is of enormous assistance when you are selecting flowers, trees, shrubs or perennial food crops for your landscape and garden areas. Within each growing zone are microclimates, which exist because of landscape features such as hills or valleys or hardscape elements including buildings, concrete, etc. Other factors such as the winter sun, wind, humidity and soil nutrients play a role in the determining how hardy a particular plant will be through the winter.

In general, the USDA planting zone map is an extremely useful tool and most plant distributors and your local nurseries provide zone information with their plants.
