more on my sickly coconut palm - BUGS??
Hey guys. If any of you have read the other thread, you'll know I'm racking my brain over what ails my coconut palm. I go back and forth on lethal yellowing, ganoderma, or simple nutrient deficiency... and being a novice at this isn't helping! haha
So I heard a coconut fall today. It was premature - not ripe - and showing signs of brown near the stem, which is a hallmark of LY. But there are reasons I'm still unconvinced.
But the main purpose of this post is that I also noticed bugs in the stem of the coconut. (photo 1) Do you guys know what bugs they are? I googled common coconut pests and didn't see any. Are they damaging the tree? Are they the cause of my symptoms? A picture is attached below (photo 1), and here is a video of them scurrying around when I flake off a part of the stem: www.matttilghman.com/20170622_124204.mp4
Ok so again, the main purpose of this post is the bugs. Regarding the other diseases and symptoms, I've done what I can and am now in 'wait and see' mode. But in case you'd like to follow along and chime in your opinion, here's my attempt at deciphering whether it has LY or not:
FOR: coconut dropped premature, with brown on stem (photo 2)
AGAINST: It doesn't look anywhere near as 'water soaked' as the ones in the literature for LY. Almost more like it just happened to ripen around the stem first. Of the coconuts still on the tree, many don't show any brown near the stem (photo 3).
AGAINST: Also the literature says with LY, they prematurely drop "most or all" of the coconuts. This is the first drop in months.
FOR: my drooping fronds are a DEAD RINGER for photographs of LY in a dwarf malayan or maypan variety, which I THINK this is (though not sure)
AGAINST: I've found a couple photographs online of severe K deficiency that look like this too.
FOR: I've read one symptom is 'fronds wilt prematurely and form a skirt around the trunk, and stay there several weeks before falling'. EXACTLY what I see. But maybe that's a symptom of nutrient deficiency too? I've seen something similar in pictures of K deficiency, but never seen it described so exactly like my symptom.
AGAINST: Supposedly the main hallmark of LY is the PROGRESSION of these symptoms. First: premature coconuts falling. Second: inflorescence necrosis and inability to bear fruit. Third: frond death and ultimately bud death. In my case it was: First: frond death. Second: ONE premature coconut fall. Still no inflorescence necrosis - still producing new coconuts (photo 4) (though not as many as most healthy trees... which could mean nutrient deficiency?).
AGAINST: supposedly approximately 3-5 months from symptom appearance to death. I noticed some nutrient deficiency in photos from 9 months ago. There is a photo of one frond "falling prematurely and hanging for several weeks" from six months ago, already longer than the supposed LY expectancy. And still it produces new fruit. (8 hanging fronds in the skirt now though )
AGAINST: another nearby palm with a more clear-cut case of nutrient deficiency, I think.
Bonus photo 5: the whole crown... almost looks pseudo-healthy from a far, when you're not looking at the skirt!

Would These Survive a Zone 7a/7b Winter?
If i were to plant these in the ground right now, which gives them all summer to grow, would they make it through our Virginia zone 7a/7b Winter?
Spots on Palm leaf ethnographic basketry toys
By Maria Paula
Hi, I'm currently studying some ethnographic basketry toys from Argentina, weaved from diffferent species of palm leaves. I've observed two different kinds of spots on some of them and since I'm by no means an expert I thought I might ask you about them. The first picture shows some dark spots that might be fungi, I was wondering if this looks like a palm disease that you are familiar with? It could be helpful to know if this was something already present in the plant material or if it was attacked after its manufacture. The second picture shows some reddish spots which are much flatter and irregular than the previous ones. I've observed this particularly on the more yellowed and deteriorated leaves (from at least two different species). Any help will be much appreciated since it could help me with the investigation (I'm sort of lost on where to look).
Photo 0046 species is Trithinax Biflavelata and 0009 is Copernicia Alba.
Thank you very much!
My Palms: A Formal Introduction
Hi everyone! I recently found this site when looking for advice about a sick palm of mine (feel free to check it out: http://www.palmtalk.org/forum/index.php?/topic/53846-coconut-palm-ganoderma-potassium-deficiency-ly-nothing/). But I've been snooping around, and this seems like a really cool community, so I thought I'd formally introduce myself and my palms.
To start, here's a view of my front and my back (I'll subsequently make a post for each of my palms, because otherwise I'd easily be above the 8mb limit) See how many palms you can find! It's my own little slice of Old Florida in Ft Lauderdale. Well, I'm not sure if it actually qualifies as old Florida - I know it lacks some of the visual features people usually associate with "Old Florida." But it was built in the 1920s, which is pretty old for Ft Lauderdale!
A couple things up front: Firstly, I've only lived here for about six months, so the vast majority of what you see (good and bad) was not my doing. Nor have I done the majority of things that I plan to eventually do. But that's not the main reason it may look a little bit 'unkempt', especially compared to most of the gardens posted here. In reality, that's the way I prefer it. I like it a little bit raw I like it to be as 'productive' of an ecosystem as I can stomach, haha.
One other thing: I must confess, I don't consider myself much of a palm buff. In reality, they aren't really my favorite plants (sacrilege, I know!), but I do like them. I am most passionate about native plants, especially ecologically important and bug-friendly plants. Now I know some palms do fall under those categories, and those I love I also really like growing trees from seed. Like I said, I do like palms, but am no expert, so please feel free to correct any wrong IDs, or notify me if something looks sick or troublesome!
OK, here goes nothing!
Naturalized Needle Palms?
Anyone's Needle Palms naturalizing? Mine are just suckering, like usual but are anyone's full blown naturalizing? Like producing seed and srpouting?
