It's iffy. The trees mostly will survive. The flower buds may not survive consistently every year esp. if you have fluctuating temp in the spring.

Rootstock for my Peaches is LOVELL hardy to zone 4, and Empress Peach is classified for ZONE 5 , and Golden Glory Peach is for Zone 5/6 . I am in Zone 5b, they should live?

With winter protection, yes, they should be ok. Reliance is considered the hardiest peach, from what I've read. Whiffletree rates it as zone 4/5. Empress is a 5, slightly less hardy, but can be grown in a pot rather easily as it is a genetic dwarf, and can thus be overwintered in a garage.

Thank you very much. any idea will it be easier to protect it from borers if it's in containers.

Like Jemmalix said, potted peach would be a way to go for zone 5 or 4. I'd choose Madison or Veteran over Reliance for better tasting fruit. I've not heard much about Golden Glory or Empress.

Move your potted into an unheated garage in late fall. Pot needs to be big enough so soil won't be frozen out easily.
