Growing Peach Trees in zone 4

Yes it can be done. It takes a lot of care. I live close to Lake Superior which has a tendency to create a micro climate. Very seldom does it get below 20 degrees below here. I have had some success with the Reliance peach variety. The peaches are a little on the small side. But what a treat!
Plant the tree in the spring. When fall comes around and the ground freezes place a layer of straw for mulch around the tree a couple feet, and about 3 inches deep. In the spring don’t remove the mulch. It will help the tree break dormancy a little late so the blossoms don’t freeze out.
Henry Fields has another Peach Tree out this year that caught my eye. I am going to give it a try. It is also good for zone 4. It is called Contender. I have listed the link below.


I have grown a few peach trees in P.E.I. for the last seven years, with good results.
I would like to expand to 30 to 50 trees, they would be located in the eastern part of the province, soil is sandy, area is the longest frost free area on P.E.I..
Am wondering whar varities would be best to plant?
Would appreciate any suggestions and help.
Thanks.

Sorry I took so long to get back to you on this I have been working on some new blogs. If you have found a variety that works stick with them. In the area we live in here we have a number of micro climates and I can get away with growing zone 5 fruit here because I am so close to the Lake Superior. I have tried a couple of varieties and the one have have had the best luck with has been the Reliance Peach. it blossoms late so it usually misses the late frosts in the spring.
Thanks for the comment I hope this was some help.
