Trachycarpus put to the test at -2F

20 posts in this topic

A customer of mine in Amarillo purchased eleven reginerated windmills with 11-13' of clear trunk from me last year for a landscaping project. This winter had two very cold spells of which the later dropped the temp to -2f. The duration of the cold was intense as well with over 60 consecutive hours below 25F. Needless to say all of them were mostly defoliated, but all of them have resumed growing with more than a foot of new foliage and a few are already flowering. I have attached a few pics.

What zone is Amarillo in? 

Great to see they survived and are coming back.   My way of thinking about these palms in marginal places has been, while they do survive and come back, if they face this kind of cold and damage year in and out, they will die in a few years or so.  Just too much to keep playing catch up for them.

Amarillo is borderline 6b/7a.

I always forget how far up there Amarillo is.  Closer to Denver than to Austin.

Seem like they are right on the

edge of hardiness limits...perfectly timed

trunk cutting there as sometimes even after

a week of warmth the bud can be lost,the one coming

back from being trunk cut should be able to self regulate now

without fear of future damage.

Impressive. And supposedly Takil is even hardier.

-2°F is the all time record low here, but with our cooler and wetter winters they wouldn't recover as quickly from such damage, if at all, despite our winters being nearly a full zone warmer (7b/8a). Subzero temps haven't occurred in over 30 years, but windmills are still marginal here.

That's some fierce cold there but good to see they've at least survived. Question is, will they have to endure repeated episodes of this kind of exposure in the future which could see their demise?

Cheers, Barrie.

Sub zero temps are not the norm. Lows are usually around 5f each year and this should be the most difficult year as they were planted just about a year ago.  Ill keep updating them for years to come.

There is a place here in tulsa that has 3 6-7' trachy that never got protection this winter.  we had 2 nights around 12.  I went by last week and they dont look so good. Will be interesting to see if they recover and how quick if they do.

I've visited Amarillo several times lately. I wish I'd have thought of talking to you and going to see these palms. The cold wasn't quite as bad in Lubbock (-4 low), and the one large, unprotected Filifera that I'm aware of here has already pushed out close to an entire new frond. Trachys didn't even burn.

Raymond Sharon has some growing in Wichita, they're defoliated, but the trunks are firm...time will tell if they make it...Glad those in Amarillo are waking up! :greenthumb::D

Maybe after seeing old Trachys scattered in Albuquerque (just 280 miles W), someone decided to really push it. Amarillo has more extremes of temperature than ABQ when the fronts storm down the plains - the rest of the time AMA temperatures similar plus some more humidity, better soils, and 12" more rain / year.

Too many repeats of that could kill them - though ABQ is 2000' higher it is protected by large mountains from most bipolar temperature swings. ABQ simply doesn't get wild swings like Amarillo, similar to how Tucson doesn't get El Paso's swings, etc.
