So I just checked out how all my plants were doing and I noticed this weird darkish brown rot on the newest frond of my Queen Palm. The whole frond is nice looking and the palm appears healthy but right at the bottom of the frond that is coming out there is this weird rot. I tugged on the spear pretty good but it isn't budging at all. Anyone know what this is? I sprayed it with some copper fungicide so hopefully that helps. 

I have the same thing on my two Mules.  Frond is ok except at base leaves have same brown rot.  Also using copper fungicide.  Spears solid but tips brown.  Have had weeks of high humidity.  I am wondering if the Christmas freeze is a contributing factor.

Have your palms recovered from this?  Mine have with the dryer mornings.  I do think the below normal cold wet mornings with dense sea fog that we had for weeks was the primary cause.

Yes, they are indeed. The wet rot seems to have dried up and the palm is now pushing some newer growth. I would have to agree that it is probably the cooler wet mornings that caused this.

lows 20's F can cause this damage

I’ve had queens do this, they always recovered fine.

The North Padre Island low temps (using Corpus Christi Naval Air Station data) during the Christmas Freeze were 31-26-26-31, with winds directly out of the north exceeding 40 mph.  In contrast the official Corpus Christi temps taken at the Corpus Christi Airport,  20 miles north from the Naval Air Station, were 26, 22, 24, 25.  Plantings on north side of my house where the (4 year old) mules are located had much more damage than those protected from the wind on the south side of the house.   Even though the "experts" claim wind chill does not affect plants wind does matter.

wind chill and wind desiccation are a little different.  New spear tissue is real sensitive to cold though.

Decided I would give an update on this guy. This thing is pushing out new growth like crazy. Already has a new frond coming out. It appears as though it has pretty much pushed all that rotten gunk out. This Queen is proving to be quite hardy.
