Most nurseries suggest planting trees using a specific plant hardiness zone as your guide. U.S. Department of Agriculture's tree and plant hardiness zone map is one good guide in helping you determine a plantís ability to withstand an average minimum temperature. I refer to plant hardiness zones a lot when reviewing individual trees.
Still, you need to remember other factors, including soil type, moisture, drainage, humidity and exposure to sun and wind can have a direct effect on the success of a plantís survival. So use a plant and tree hardiness zone map as a guide, but keep these other factors in mind when deciding where and what trees to plant.
