hardiness zone is a geographic area defined to encompass a certain range of climatic conditions relevant to plant growth and survival. 

We are located in hardiness zone 3, all our trees have been grafted and grown here and have survived a year or two in our winter.

Click the links below to determine your hardiness zone. By using this map, you can choose the best plants and trees that will be more likely to thrive in your location. However, this is just a guide and there are many factors in assuring the success and failures of trees. Changing climatic conditions and other factors should be taken into account.

Local climates within the zones known as microclimates can also yield different results. For example, planting your trees next to such as a body of water, a southern slope, in a sheltered yard or in urban areas may make your zone 3 into a zone 4 climate. On the other hand, planting your trees in a low spot or exposed area may drop your zone 3 into a zone 2 climate. We do our best to accurately rate the hardiness of our trees and you can find their hardiness description on their product page.
