Princeps hardiness ?

[WSimpson]

I thought Trachy princepses were as hardy as regular Fortunei but I don't remember my Princeps having what looks like winter damage on it in past winters . The newest  spears look fine but 2 fronds and 1 spear  has  damage . My lowest low last winter was 16F and after that I had 5 lows in the lower 20'sF -25F . A mild winter for here . 

How hardy are they ?

Thanks

Mine has been unscathed by temperatures around -8 to -10C but if the freezes last longer (several days without temps above 0), small fissures and cracks start to appear on the leaves. But that is only cosmetic damage. They are pretty tough where I live.

That's fungal damage caused by moisture freezing in the spear and damaging the tissue then fungus attacking this slow moving freeze damaged tissue in the spear.  Treat with copper fungicide each spring (Late Feb - March) after cold/wet freezing events when temps warm some to minimize this.  If it gets out of control it will kill a palm.

Yes.....palms are not really meant to stop growing..

ice in the spear area is like crushed glass to new tissue...  even a prolonged period 

of none growth can cause this....every one of my SMALL palms had similar damage from

moisture and "dormancy" as the temps never went below freezing in the rose cones but growth stopped.

Actually all but one, surprising the smallest a T.Geminisectus did not.

I would just snip the frond tips off at the brown part on that one frond or cut the whole thing, your call.

Back in 2018 mine lost all but 2 fronds while other windmills did much better.  However, I also lost 3 large sabal minors.  All of the damage occured in March when temps were going back and forth.
