Proof of Life

This Cyrtostachys renda survived a low temperature of 42°F with a gloomy high approximating 50°F. Let’s see what happens in January:

Hoping for the best!

Looks gorgeous at the moment. I never dared plant my two over here.

In reading a few details regarding this magnificent palm, Steve Stern, well known nursery owner extraordinaire, opined that this palm is not as sensitive to low temperatures as previously reported. He believes that low temperatures do make the palm susceptible to a kind of fungus that is indeed fatal if not treated prior to the cold event. I will continue to update to see if this specimen continues unabated or declines in the event of some predicted upcoming additional arctic incursions later this winter.

He told me that, too. I sprayed mine with a solution of Dithane 45 every couple of months from Nov. through Mar. They never got sick.

Beatiful palm. Is there any palms that look similar* but are hardier?

It's good to hear other results on Mancozeb, Hferrel87 told me it was his go-to fungicide for crown rots after cold fronts.  He used it on the B. Alfredii seedlings after cold fronts in order to prevent and cure spear damage/rots/etc.  I bought a bag of Dithane M45 but haven't used it yet.

Oh! Keep us apprised. 

Come March I want the full Monty regarding how you did it.

44c has been my low.

To Palmfarmer’s question, I believe that Jeff Searle championed a variety of Cr that was far more cold tolerant. I bet Ryan (Palmarum) could provide information on how this variety has performed. I believe it had performed successfully as far north as Orlando. 
 

Alex, you should have no problem whatsoever if your current low temperature for the year is 44c! I can only guess that you have moved from Tijuana to an equatorial, climate of unknown parallel! The more I read, the question becomes, whether or not my neighbor has properly treated this palm with the fungicide described by Steve Stern:

A lipstick can handle a few days of cold above freezing if your overall conditions are warm and humid the rest of the time. But a few weeks of 40's and 50's will surely bring about plenty of rot.

Please note the month of December 2022 for the general temporary nature of cold events in this area. One caveat was January of 2010, when we experienced no freeze but five (5) straight days of highs in the mid-50’sF and lows in the mid-30’sF.

Following this thread as I have finally added CR to my small “collection”.   Mine will be a container specimen that will come in doors if necessary for our rare “cold snaps”.
 

To your question quoted above, for me it’s the Areca vestiaria red / maroon.    Somewhat similar look and I believe it is actually just a bit more cold hardy.
