Do Queens fall from Flooding?

Let me premise this by pointing out within a few miles of my house
there have been decades-old thriving mature queens everywhere.

These queens were 3 years old when I put them in six years ago.
Three years ago we got 4 straight months of rain but no floods. Queens
were fine. Then we got this prolonged drought which broke last month
and saturated the ground. Then we got these freezes that shattered
the old records by 5F. Those murdered scores of my fan palms, but the
queens looked green and delightfully happy for no apparent reason.

Then two days of record rainfall just ended this morning. There were
some strong gusts, but nothing like the tropical storms these queens
have been through. For instance, even my blackened fan palms have
no broken limbs.

The queens are still sitting in saturated ground, like
most of the entire area looked like a lake for the first time in history.

I looked out my window this morning, and every single palm had a branch
hitting the ground...all pointing the same way (away from the wind). The
most exposed queen was completely toppled at the waist. I included
a picture of a few.

Otherwise, the crowns still look green, and most of the trees look happy
and show normal die off of fronds. It's like they sucked up a lot of water
all at once and snapped. Maybe this is the beginning of the end for all of them?
Maybe this is latent freeze damage that has made the crown fibers mushy?
The breakage is identical: right where the crown touches the branch.
As I said, these have stood up to 70mph winds every year or two.

Anyone seen this behaviour before?

Since I posted this we've had four days of
moist Gulf weather. 70F (20C?) and varying
rain.

I treated the crowns with Daconyl after the freeze,
but historically unless I got them before a freeze
it was too little/late.

Answer to my own question:
All of these trees have turned almost
white. They are molding crown out. For some reason
they were just the last to show freeze damage, possibly
because the mold had not set in yet. With
all the rain/wind more copper fungicide will just wash away.

The fronds are cracking off. This whole area looks like
Planet of the Apes. I went to town yesterday and it was quite
a site to see a petticoated palm 60 feet in the air reflecting
bronze in the sunlight. I wonder how long it took to get that
high and how many storms it weathered just to end like that.

Mature landscaped Roebellinis all over boulevards are almost
black. Very few Queens look healthy.

I think it's going to revise a lot of the landscaping textbooks. I don't know whether a fungicide would help if the crown has frozen. Unless they're something like the multistemmed Dypsis, or Caryota, etc.

I saw a thick-trunked ~12M Queen in town near the river surrounded by cement yesterday
all yellowed and drooped. That area is (was) hard-core 9B with all kinds of nurseries and exotic blooming
plants and bamboos that are 10+ typically.

I heard the south tip of Texas lost it's 10 zone rating years ago after a re-rating due to some
incidents like this one. Our weather on the Gulf Coast, has been determined by events
far West. The wind patterns are such that we get aftermaths of Pacific hurricanes that hit
Cabo, etc. On the other hand we didn't have any Gulf storms this year.

Yep, the trees were all green a few days ago, then the fronds went, then the tops of the crowns,
then in the last day right down into the hearts: albino queens. I'm out there sprayin' like I'm
kickin' a dead horse.

Now the only palms I have that look pristine are Med Fan Palms; I will be long dead before
they get some size.

I thought I'd post a follow-up. One week later
after spraying. No signs of life. And some of the
other landscape has changed too. The good thing
is that my new pup has something else big to chew
down he can't already kill.
