Cold damage?

Arenga engleri..... saw 22 F under canopy 5 months ago. Is this cold damage?

That looks exactly like cold damage.  The good thing is that it looks like it pushed the damaged part out.  It should be fine.

Yep. Happened to all of my Queens, but it wasnt bad enough for the fronds to completely fall apart, just the leaflets were brown and fell off as the spear pushed out. My Queens are becoming rockets now, its only May. Looking forward to this growing season!

That may be bud rot since the older leaves look fine.  Perhaps the bud/new leaf was notably more cold tender than the older leaves.  Most cold damage I have seen happens to older leaves first or at the same time as the newest leaf, rarely do I see the newest leaf burn and the rest are fine.  I have had bud rot on a few palms that just pushed through and recovered without any fungicide.

I do think it's cold damage.  The same thing happened to my Livistona decora.  I think, like you said that new leaf is more cold sensitive.

Here is how the new spear looks now after it went through 23°F during the Texas arctic blast.

And here is how the rest of the palm looks.  There is no damage to the older fronds.

I had spear pull on a smaller decora with no damage on the older fronds. It has already pushed a new spear.

Noticed similar thing on other arenga appears and butia Jubaea queen hubrids they all look like they’ll grow out of it
