Pindo palm issue

[Harm]

We just got back in town after a week and one of my pindos  seems to be in trouble.  The center is brown and some of the frawns are turning black.  They were planted about a year and a half ago.  We are in zone 8.  There were a couple of days the weather dropped to 15 degrees but not a tone of frost.  Any help is appreciated.

15° is pretty cold for a smaller Butia odorata but I think yours should recover.  Lightly tug on the damaged center spear and see if it comes out.  If so you can treat  with hydrogen peroxide down the hole and you'll likely see/hear fizzing.  Follow up with copper fungicide treatment.  When it warms up the palm should push a new spear but the frond will probably be deformed.  Then it should grow normally after that.

Also being in Zone 8a/8b and having lost considerable palms in the TX 2021 Palmageddon freeze.  I would treat with the Copper Sulfate spear drench whether the spear pulls out or not.  Chances are even if the freeze did not kill your palms crown, the freeze did destroy some of the tissue.  Dead tissue is incubator for fungus and if you add in moisture and cool to cold temperatures,  you will have trouble with fungal growth.  Hydrogen peroxide will kill bacteria, and fungus, but can also kill live tissue so I limit its use.   It is a good idea to keep the damaged area as dry as possible from rain.  This will discourage a wet environment which promotes fungal growth after freeze damage.  That is my two cents worth.  @Fusca makes a valid treatment point too.
