Back to USDA zone 3?

It's been several days of -20 windchills and -10's overnight. Not much snow cover to insulate the roots on my trees either, but hoping my deep mulching keeps them warm enough. I'm guessing my peach trees won't produce as I've heard that -20 can kill off the fruit buds, even in trees that survive in zones 3 or 4. Mine are Red Haven and Elberta.

I never thought I be grateful for single digit temps both sides of zero, but now you guys in MN and WI are making it feel down right balmy here in Western NY! I'm thinking you have to be pretty picky about what trees are going to do well in those conditions.
Windchill does not affect trees actual temp is the measure , wind chill can and does desiccate trees but windchill only affects objects with internal heat and speeds the removal of heat but will not lower temps lower than actual temp
Hardiness is all about actual temps , Most of the windchill hype you hear on the local weather is about selling the fear , although -20 windchill is nasty

How cold did you get? And concerns on those zone 4 trees?
We must have some cold pockets in my area. I did not believe that thermometer, but a friend had a -29 cold pocket on his car thermometer at 8:30 the same morning.

Not too worried on temps yet , lots of research has been done and most points to sudden changes to extremes example few years ago fairly warm stretch then sudden drop off trees were not hardened enough and we lost some young honeycrisp the top died back tree resprouted above graft union we let em go and they recovered lost a year of progress . We have never had massive damage other than those young honeycrisp that year , we lose a few every year to something but I cant blame temps completely . Lowest we have been -23 this year and the trees were hardened well before
Sandbur did you ever find or try a prairie magic , I see jungs seed catalog has them in their line up again may be just the ticket for the tundra

I have a few varieties that are seeing their first -30's. I don't think we have had those lows in 3 years so it will be interesting. I also have some that had severe winter kill in their first winter 4 years ago and have turned into nice trees since. I am hoping they will fair better than their first winter out of the nursery. They are also incased in 3' of snow so the roots should be fine.

We have been in the -20's a few times in the last week or so... a balmy 16 degrees on the positive side today - pretty much a heat wave..... I've got 80 or so new Dunstan chestnut trees in the ground this year transplanted to the field from pots in the fall. We do have some snow cover... but it's just a waiting game till spring and I am concerned. It would have been nice to have had a milder winter for their first and... :-( maybe only winter. I have chinese chestnuts that are close to 10 years old now so we will see. Im pushing the usda growing zones on a few other types of trees too.
