The Q&A Archives: Zone Harniness

Question: We just purchased two peach trees from home depot. on the tag, the zone hardiness is good to -30 degrees. When I looked it up on the internet, it said it was for Zone 5, and only good down to -20 degrees. I want to know if this tree is going to servive opur Minnesota winter, or am I out of my money?

Answer: According to the Minnesota extension service, "Stone fruits all have hard pits at their center and include peaches, plums, cherries, and apricots. Most stone fruit species, including peaches and sweet cherries, are unsuitable for growing in Minnesota; they are sensitive to winter injury and, even if they survive, bloom before the danger of killing spring frosts is past. Stone fruit species that do grow acceptably well in part or all of the state are selected European and hybrid plums, cherry plums, tart cherries, sand cherries, and Nanking cherries. Two hybrid apricot cultivars, Moonglow and Sunglow, make fine ornamental trees, but rarely produce fruit in Minnesota gardens."

I would be inclined to exchange the trees for another type of fruit tree. Here's the website from the University of Minnesota that lists suitable fruit trees for your growing region:
