I have a question about the reliance peach tree. From my readings elsewhere on the net, people have claimed it hardy to zone 4 or -34c. Edmonton has not gone below that temperature for many years and my backyard has not gone colder than -30 for at least the past 10 years. Although Edmonton is rated zone 3a or -40c, that was based off the international airport readings which are consistently -5 to -10c colder than in the city. People in zone 4 MN, WI, and ILL have grown this tree with no problems. Where is the closest city that I may pick up this tree to try it here? Kelowna is the first one that comes to mind. And what kind of wind protection can I offer it to protect the buds?
