Foxtail Palms

[Cascades]

I manage an HOA in Lee County, FL.  We have many foxtail palms in our community.  All of a sudden they are all turning yellow and dying.  These homes are 3-10+ years old and don't understand why this is happening all of a sudden.  There are a few other types of palms that are dying as well but for the majority it is the foxtails.  Our landscaper is saying it is a deficiency, but why all of a sudden and why the majority of them all at the same time?  I find that hard to believe.

Can you provide a photo or two. My first impression would be something like Leathal Bronzing but photos are necessary to be more certain.

One of the leading reasons for palm trees to decline in Florida's commercial landscapes, like an association's common property, is due to overtrimming. This occurs when the fronds are cut prior to them turning completely brown, robbing them of nutrients. Are your landscapers cutting off the fronds when they still have green on them?

No.

I'm not sure why there would be a sudden and dramatic change in the whole community but I see a lot of yellow foxtails in southwest florida, they seem very prone to nutrient deficiencies in our soil. That would seem to be the most likely explanation.
