Just had these pindo palms installed about a month ago.  The lowe leaves are turning brown.  New growth shoots look good.  Could this be from over/underwatering?  Or potentially just transplant shock and expected?

When first installed for reference

Where these crated or field grown trees?

They were field grown trees 

These don't look too bad to me.  I think more info about your location, soil type, and watering could help PalmTalkers wiser than me judge whether you should make any changes.

Have been watering three times a week, but just yesterday started water it a bit more due to new sod around it.  Soil has a lot of clay a foot or two down but don't have soil specifics

The oldest fronds dying seems reasonable for a field grown palm and stuck into a 15-30g pot.  It's not a lot of roots for a palm with 3 or 4 feet of trunk.  If it is growing a new spear I'd mark them horizontally with a sharpie and check to see if it is moving.  It may not move much, since it is a recent transplant.  If the newer fronds are doing more than brown tipping then I would be concerned.

I've transplanted 4 Pindos in the last two years....all suffered spear pull, even after the spear was initially growing, and after noting it turning brown.

The first two have recovered and growing well, the second two (planted about a year later) have not but the rest of the palm looks fine.  However, I fully expect these to recover as well.

First palm is the oldest transplant, second and third are the newest.

 

So these look fine so far then?  I'll continue to monitor and see how they progress.  Good note on the sharpie to see if they continue to grow.
