Using the Massachusetts Growing Zones Map 

Gardening is an enjoyable and popular hobby. Gardening can be frustrating if you plant the wrong types of plants for your planting zone. Save yourself the frustration and take the time to understand which plant zone you live in. Thankfully, the USDA created a map to help gardeners and growers determine their planting zone.

The 2012 USDA Plant Hardiness Map is the best gauge for determining plants suitable for your climate. The USDA Plant Hardiness Map is relatively easy to use, too. To determine your planting zone, click on the state of Massachusetts. After clicking on the state, simply zoom in on the general area of your location.

If you want a more accurate determination of your planting zone, enter your zip code and address into the search bar. Match the color of the map to the color-coded legend on the side of the map. The color of your location is your planting zone.

The temperature, which is a significant factor in determining planting zones, varies by location across the state of Massachusetts. Temperature also influences the length of growing seasons. Because the temperature varies so much, Massachusetts has six planting zones.

Your planting zone may differ slightly from the surrounding area, too, due to your garden’s micro-climate. Soil, temperature, slopes, and boulders, among other things, can affect the micro-climate of your garden, which in turn affects which planting zone your garden is in.

It is of the utmost importance you understand your planting zone classification before planting any fruits, vegetables, or flowers in your garden.
