Wine palm diseases

[Yankee]

Hello everyone. New to the forum! Have a few large wine palms by my house, this one in the picture we’ve had for at least 8 years and lately the heart seems to be struggling followed by other branches that look pretty wonky. Was wondering if any one had any advice on what could be causing this and if there is anything I can do to help it?

There are only 2 wine palms that I know of in SE AZ. Both are growing in part to full shade. I suspect yours is a hybrid based on the lax look of the leaves. Do you know their origin? Would you mind posting images of your other ones?

Looks like the spear is drying out. I can't speak to diseases per se, but a (somewhat abrupt)change in the uptake of water by the palm could present itself like this.  

Water change(suddenly not getting water) caused by:

Root damage(recently transplanted, overfertilization issue, insect/rodent, etc... ), plugged drip line. 

Just some thoughts. 

Nice palm(s)!

- plugged drip line 

Unexpected. So soil moisture should be checked every couple days.

Not saying that. But if a palm is unexpectedly desiccating, soil moisture could be impactful. 

Mainly why natural groves of filifera die out around the San Andreas fault.

I am guessing it may be the same with Jubuea .

Only saying that once the drip is installed, we shouldn't walk away for a year. Best to check once a week that it's functioning.

We have a drip system for all trees that gets checked regularly so that’s why I’m a bit baffled! i know in the photo it looks super dry but the heat drys the top layer by morning. I’m still not exactly sure how to use this chat to properly address each point but i will gladly post some picture of the other palms and maybe I’m incorrect about it being a wine plam. Maybe crossed with pindo/queen?

@Yankee Use the quote button at the bottom of each post to respond to an individual or question in a post.  Probably the easiest.

You can also use the "at" sign(@) followed by the username to talk or respond to someone. Like @jwitt or @Yankee .

Pictures can be very helpful.  They are also enjoyed by "us" palm perverts.

Welcome to palmtalk. There are experts here that can surely help with your palm issues.  Speaking for myself, I enjoy seeing palm(s) that are out of the usual for an area. That makes you someone we all can learn from. 

The palms, regardless if they are pure Jubuea or not are special and somewhat uncommon, even in somewhat palmy Tucson.

My water concern comes from the one picture where you can see the spear, and your location(Tuscon).  I know this year has been pretty dry, even by our southwestern standards in a lot of areas.  Factor in the added heat, maybe something (water) that was sufficient in years past is just not enough this year for something that was just enough(near the edge) in years past.  My thoughts......

Adding more pictures showing your good vs. suffering palm would be helpful for your current problem and species identification. 

You have some special palms that are out of the norm for your area. That alone sparks interest for us "palmophiles".

Again, welcome to palmtalk!

I like everything you just said.  Yes for those who love Palms, just seeing one in an area surrounded by cold loving trees like conifers gives a warm feeling.  Here is an early morning photo of a Pure Jubaea growing 100 yards from the ocean surf.

[Dwarf Fan]

Banana Belt at that 100 yards distance from the ocean what is your soil like, is it still PURE beach sand? I read that nematodes in beach sand are killers of Jubaeas does your property sit on normal dirt by chance?

Is it a FLAT 100 yards from the ocean or are you perched up on an elevation with a vastly different soil composition than at the shoreline?

On the larger palms lately spots started appearing on branch, can’t seem to figure out the issues on the larger one as well as the smaller one posted here and previously with a dying heart. These are my dads pride and joy would love if i could find a solution to these diseases?

You are correct in their identity. Does he have 5 in total? I will have to update my known number of this species growing in SE AZ from 2 to 7.

I started growing 2 of these in '14. I have 1 left growing in partial shade. The 1 that died started getting ugly spots on the leaves, and at the time I attributed it to excess summer humidity (a common assessment to their decline in southern states). That 1 died, but it was growing in full sun. My current hypothesis is that full sun coupled with warm nights stresses the leaves, and fungi have the opportunity to eventually devastate a pure wine palm (non-hybrid), which can lead to it's demise. The one I grow in partial shade has very few spots, and is growing fairly well. Based on my current hypothesis, I believe the last few summers with higher temps, and warmer nights are likely the cause. As far as the 1 with the dying crown, it might be a form of bud rot from a different pathogen.

Thanks for your update. I hope you save these stately palms.

Quite an attractive garden! I recognize a few species that aren't very often seen in the Tucson area;

Paurotis Palm - Acoelorrhaphe wrightii

Chilean Wine Palm - Jubaea chilensis

Sabal mexicana

Mazari palm - Nannorrhops ritchiana

Bismarck palm - Bismarckia nobilis

Ribbon Fan Palm - Livistona decora

Brahea clara

Chinese Fan Palm - Livistona chinensis

Brahea decumbens

Chamaerops humilis var. argentea

A couple look like mule palms

2 images are showing what look like some types of grass trees

Image 18 is a mystery

BTW, when using a phone, if you shoot in portrait mode, the images won't be upside down.

Hi 71°, Lo 45°

 #18 could be a Chamaedorea ? ..Can see red seeds attached to it.

#23 Trithrinax? .. Spines on the trunk were the first thing i noticed.

..Agree w/ Tom, nice garden containing a bunch of palms you rarely see anywhere in AZ,  let alone Tucson.

To my eye, Jub x Butia is shown in a couple of pics (e.g. the last one of recent batch) and possibly one Parajubaea as well 🤔?

#2 could be a Parajubaea torallyi.

These look a lot like it on Agaveville:

The last image does look like a JxB.
