What's going on with the Foxtails?

[EricSatBch]

I lost a foxtail palm earlier this month and can't seem to figure out what happened to it....all of the fronds turned brown and it stopped growing...all other foxtails in my yard look great.  I have been noticing area my neighborhood there a handful more dying.  Any ideas?

Interesting. That’s a shame. Usually foxtails are super hardy

Could it be the lethal bronzing that seems to be taking out lots of palms across Florida and Texas? Might be worth looking into.Other choice might be freeze damage but those are big,mature tree's, that certainly have seen colder winters than this one.

This was my first thought as well.  I hadn't seen any showing symptoms here.  We're one of the worst affected areas by Lethal Bronzing.  Definitely not cold damage during this extremely mild winter though.

I see the sod goes right up to the trees. Is it possible something in a lawn treatment caused it? Is your yard professionally treated? I guess it would mean all your neighbors had that too which is probably unlikely, but thought I would suggest it.

Agree that it’s not cold damage in Satellite Beach as I only got to 35 in my cold pocket west of I-95 in Daytona Beach.

I think it might have gotten down to 38 or 39 maybe once or twice this winter....it was very mild, however seems like we have had a lot more ups and downs with the temps than previous years....definitely not cold enough for me to be worried about any of my palms.  The photos I uploaded are from around the neighborhood....I am seeing yards with several healthy foxtails and one or two dying foxtails right next to them....I don't see this happening with any other palms in the area and we have a wide range being in 10a...only issues I might had had in the past with foxtails is dwarf, limp or frizzled fronds which has been corrected pretty easily with some nutrients and/or copper fungicide.  Nothing is soft or mushy....it is just seems to stop living....lethal bronzing might just be the answer.

@EricSatBch Were the ones that are dying pruned of the flowers?

Look at the trunk and see if you see lots of little holes.  I have had something in one of mine that killed. Past that I usually see this in areas where it's to wet for them but that doesn't seem to be the case.

We've had a warm and rather wet winter.  You pretty obviously don't have a nutrient problem.  Bronzing or something similar has been taking out palms more or less at random.  Heathcote Gardens in Ft Pierce lost a Sabal, then a clump of Phoenix reclinata.  I'm seeing sporadic dead palms, typically Sabal, around Vero Beach.

I am having a similar issue but all the research I have done says foxtails are resilient to Lethal Bronzing.
