Advice on ailing Brahea armata

[DKinLA]

Hi.

I'm new to palm trees and this Forum and could use some advice.

Two months ago we planted a mature Mexican Blue palm in a raised bed in the corner of the yard.

It gets 8 hours full sun. Light watering 3 times a week from our irrigation system .

I have deep watered it on weekends since it was planted.  Soil seems to hold the moisture, sand/clay mix,  its damp but not sludge. 

Daytime temperatures here in LA are from 80's to 100 over the past month.  I've fertilized it once with Miracle Gro for Palms (slow release).

Issues:

1) Middle row of fronds turning brown (see picture) while new growth is fine.

2) what have been very nice flat branches(?) now seem to wilt in the center (picture)  

3) blue color has faded to light green

 So am I under watering it with this heat?  Or overwatering ?

Does it need more fertilizer    or a different type ?

Any help is appreciated

Probably a nursery grown palm not used on full sun. It all looks like sunburn to me. On the other side Brahea is quite tender on root disturbing so....

Looks like sunburn to me too. Assuming by LA you mean Los Angeles and not Louisiana? If so, the heat wave we have had has been a little rough on newly planted stuff. I had several palms planted this year experience similar browning. It will grow out of it.

Thanks for the Replies.   

Yes, Los Angeles.   The Mediterranean Fan palm seems to enjoy the heat and smoke !

I don't have the expertise most here have, I'm up near Magic Mountain 40 miles away from you.  I lost (3) of (60)  Chamaerops humilis in 5 gallon black plastic for 6 years and germinated from seed Jan. 2010.   Each was up against the block wall where the IR gun showed 135-138 deg. F....I cooked the roots and palm.

LA heat and inland desert heat are not the same.  Chamaerops are OK in arizona desert but they do take a burn during the hottest time of the year if fully exposed.  Yes the west facing block wall is NOT a place to put most palms.   A number if species can survive if they dont see the hottest western sun while sitting next to that 135F block wall.   I generally used some shading of the wall to reduce the oven roasting effect in arizona.  A black nursery pot absorbs LOTS of light from the sun and converts it to heat.  A black potted palm near a 135F wall is something you learn not to do with any small palms.
