Dypsis lanceolata: What's Wrong?

attached are a couple pictures of a Dypsis lanceolata that has some disturbing discoloration.  I am the worst at identifying pests, fungus, and other plant maladies, and need some help figuring out what is wrong and how to fix it.  along with the change from a nice dark green to a reddish brown, there seems to be a softening of the tissue.  is this thing a goner?  should I cut down the tallest trunk and leave the small suckers?  any help or answers would be appreciated.

Looks like it's suffering from a bit of sunburn.

If you can cover the top with some shade cloth that should help. Lanceolatas can fry if you move them too abruptly into the sun (as I've learned the usual [hard] way).

they're sun sensitive out here. Still acclimating is my guess.

I believe that even if the main trunk dies, the smaller one will survive.
But it seems you just planted that palm, so protect it from sunburn, water and hope :)

can too much sun cause a trunk to soften?

Soft and squishy? Sounds like rot. Maybe it's my failing vision but does the stem in your photos appear to be "shriveling"? Back in 2010 after the dreadful cold I had palms dying all spring and summer from belated cold damage. Some of them started shriveling as the first sign of impending death. Not saying your palm was affected by cold nor what may be the source of rot. Dypsis lanceolata have been wimps for me. I lost two from rot in my back yard jungle; they just keeled over. I have one left on my garden lot. After burning in the sun, it seems to want to live and is starting to cluster.

Absolutely. I have had this happen a few times over the years. In fact I am losing a seeding Hedy because before I left for Madagascar I cut out a bush that protected the trunk from late season low angle sun. Heatwave burnt it and rot set in soon after.

yikes!! I hope you can save it. That looks like a very old specimen.

when did you first notice the browning?

have you tried a fungicide drench to help prevent the yuckies from creeping in?

I noticed it about a week ago, and it has spread upwards toward the crownshaft since then.  I haven't tried anything other than placing a potted plant in front of it to give it some shade, but a fungicide drench may be a good idea. at least it couldn't hurt.  the shade cloth is in place to shelter some other smaller palms recently planted in the same area.  its just a bummer this tree is struggling... maybe three really warm years (and the low sun angle) is finally wearing it out.

Lancies definitely appreciate some shade when they're younger, especially far from the coast. I note that you're in Long Beach, but parts of it go pretty far inland, perhaps enough to avoid the beach effect. I've killed a number of them by giving them too much sun too fast.

If yours was recently planted, it might be worth digging it up and potting it up and re-homing it after it recovers.

Sounds like the smudge is heading towards the meristem, if it wrecks havoc there, it may be all she wrote for that trunk.

I don't think it's morphing into  "Black Stem". :huh:

Grant, here is what is what is left of my once proud, seeding Hedy. Sunburn can be a killer.

Len. That is a tragedy. My seedlings fried out here in Costa Rica in partial mid morning sun. I'm thinking I should have had them in total shade.

Jason, this guy grew under canopy of a CIDP for many years. Then about 4 years ago the Canary got Fusarium and died. It never could handle the sun. But I had a tall shrub that protected the trunk. Before I left for Madagascar, I cut it out. Stupid mistake. Oh well, new planting location just opened up :) 

have you seen any Hedy's growing in Costa Rica?

Back to Grant's palm, is it toast? Here a fungal thing would be suspected. 

 

Just never seen sun burn like this on a palm. Here they just turn crispy.
