Peach Trees in Minnesota
I've heard of some people successfully growing peach trees in the southern part of Minnesota. I live in the St Paul area (zone 4-b), and I'm determined to grow some peaches for our family to enjoy. So far, it's been very promising. Last summer I planted a Polly white peach tree, (zone 4-5 -20F) and it made it through our winter no sweat. (although it was a mild one) It has about a dozen flowers on it right now. If the tree fruits, I'll probably let about 4 or 5 fully develop. I'm excited about the possibility of biting into a fresh off the tree peach this summer.
So today, on a total impulse purchase...I picked up a Redhaven peach tree from a local nursery. I was so surprised to see it there, I just had to buy it. From what I've read, it's cold hardy, but a tree for zone 5. I thought about planting it in a 1/2 whiskey barrel, and moving it into the garage for the winter. But, excitement got the best of me and it's already planted in our yard. I have some ideas to help it through next winter, including an idea for a cover and lamp for some heat if some nights get close to -20F.
Anybody have experience with peaches in MN? Or pushing zone limits with other fruits?
