How long ago after the event was this picture taken? This sounds awesome but also a bit hard to believe. Was there any heat source?

The true outcome will be more obvious in the coming months, perhaps a bit sooner. Happy new year to you too.

Seriously good luck,  but -25F with no heat is not a good idea at all.   0F is probably death if it got lower than that in enclosure

Palms in Alberta? You're really optimistic.

If it was March now, then you could well be counting your chickens. Unfortunately we aren't even into January yet and the worst of winter is probably yet to come. You're going to have to leave that protection on there for at least another 2 months, possibly 3 months even. Hopefully it will protect against the -32C you have forecast next week again with a daytime high of -26C.

Looking at the condition of that palm right now, I am sceptical that it will survive to mid-January even. However, I obviously wish you the best of luck, since you're going to need it! No palm will take 3-4 months solid of freezing temps. The highest I can see in your forecast is -9C. Any idea how cold it is inside the little palm house, or how cold it got in there during the -32C night? I would avoid taking that lid off, period, or the temperature inside will equalise with the outdoor temp.

Dry-summer Oceanic / Warm summer Med (Csb) - 9a

Average annual precipitation - 18.7 inches : Average annual sunshine hours - 1725

Without heat I see no way it will survive.  -25 f. Is cold a lot of winter left.

Plant more seeds for future years when your winters will be more accommodating for these Asiatic exotics (as they eventually die from heat stroke in more southern climes).

They are easy from seed.

-32, is that Celcius or Fahrenheit?, not that I think it makes much of a difference, that sounds seriously  COLD. You guys are a hardy breed.

G'd bless and Happy New Year!

Any news and also photographic evidence from your palm @Jason gillies?

Also, excuse my ignorance, by  Bulgarian windmill palm you mean that you've secured the seed from a Bulgarian Trachycarpus fortunei or for some other reason?

It is a selection along with "Plovdiv" sold by a Bulgarian nursery (palmi.bg) and claimed to have a legendary coldhardiness (-21 C) which has never been replicated as far as I know.  But even that would not be enough for Jason..

Basically this Bulgarian Trachy myth started when it had been reported to take down to -18°C and some geniuses reported that news here in the US as Fahrenheit.  Thus I believe a Bulgarian will still be damaged under 5F and die under 0F in general terms.

I agree, I think its total hype.  Just regular trachys and as far as I know those infamous Bulgarian ones all died from cold in the end anyway.

Same with Trachycarpus "Tesan". While they may look a bit different I have yet to see one that survives longterm (10-15+ years) unprotected in a place that regularly sees -15 C or lower for more than a couple of hours. Here in Europe, it is commonly accepted that leaf damage can occur at around -12 C and anything lower will lead to partial or full defoliation and can be lethal (unprotected plants that is and depending on the duration of the freeze and other circumstances, of course).
