I have had a similar problem. I have had a few plumeria s that are dead wood in the middle of the branch or trunk and have had to cut them and root them.

I have the same problem with one of my in ground plumerias (been in the ground for 4-5 years). The cracking and peeling of the bark has been severe and left just the core of the trunk. In fact, a couple of branches no longer have any strength and are hitting the ground. No one can seem to tell me what caused the problem. I have another plumeria that is developing splits like you've shown. Have you received any information regarding this condition? Thank you!

Wow, I haven't seen anything like this before, but it is quite worrysome. Please post your findings if you ever find the information. Thanks!

Hello Everyone.

I agree with sunseeker, it doesnt look good.

Could it be some kind of beetle (borer) that is infecting them. I remember Karen from Maryland said that she had them at one point. Maybe you can find her email..if u have a hard time finding a post from her..email me and i can relay the message for you.

Is the stem still hard? SOft?

How many are infected?

One thought...if u wanted to try and do an experiment on one and see if this would help...

Take one of the limbs and use the tile and sealant that we all use in Brown ot tan,whuch ever matches your stem and "patch" it up with that.

It would be nice to see if there are answers to this...

Have you called FLorida Colors or ask anyone from MPG Forum?

Hope this helps...

Hm, the first six photos look like a sunburned area that split from the stress. It looks like cambium tissue starting to overgrow the dead sunburned area, trying to heal itself.

Then the seventh photo looks like all the "cankers" are starting at the point of leaf nodes, especially in the bottom node where you can see the black of possible rot. Maybe the rot caused dead tissue which, again, is being overgrown in an effort to heal the area.

The eighth photo also has what looks like sunburn. Maybe this is what happens when unusually hot weather is followed by periods of cooler, damp weather on a plant stressed by sunburn?

I have seen this on an outlying branch in one of my trees last year. I left it alone and have not observed ill effects. However...I am pretty sure it was not a flower producing branch this year nor did it put out much green wood. I don't know enough to say if its related or not.

I treated with Three in One Fungicide at a later point for spider mites (unrelated in my opinion) and gave a pretty good dousing to that area as an afterthought. Perhaps it helped.

I agree with Jen it may be sunburn related. It would seem odd to me that an insect would precisely attack at leaf nodes.

Maybe treat with a neem oil fungicide for 1 or 2 treatment cycles and then seal like Laura says? Or treat and let it scar over by itself. Supposition on my part but I don't think Neem oil has ever damaged a Plumeria.

Correction: after taking a closer look I found both tips on this branch have active inflos.

Yes,me too!Agreat year for Tempest,Lunar Eclipse,Tesla Girl,Danai delightAussie Con.,I actually got a forming stalk on Crystal Rose[WOW,that one is super-coveted!!]but it didnt develop,drop pre-bud,but thats ok,it's only a year old.I noticed one of my massive aztecs had shed outer bark,but its old and massive,so..then Lunar E.developed a 'hole'almost,right by graft.Almost like overnite!It's propped and tied up now.I have some 55 asst.from all over,and now I see this appearing to some degree or another to 14!That's a terror call for me,as some cant be replaced!I was always seeing plumes in Fla,guzzling sun,hotter the better,but now I'm told remove em from late afternoon sun,when it's around 102 degrees.This was never an issue in Hawaii.How are ya supposed to know what to do?water,soil,fertilizer not the problem.I just misted the areas with anti-fungal and a little neem,as whitefly is bad this year.What is this sealer you mentioned?e-rooting Thai plants is like betting all your cash in Vegas-are you nuts?I think re-planting deeper would only invite rot disaster.This has occurred in both potted plants,plus some in ground.I cant even sleep.I'm not going into retail sales,I just want some show-stoppers in my yard and maybe give some cuttings.I had a mite attack on my 4yr old Emperor Lychees first time this year,also.but thats over with,now,thankfully.At least I found this page and know I'm not alone>Pls.anyone with success,help if you can.The special needs kids come from school every year to see and get cuttings.If nothing else,pls.send your Prayers to Jesus on our behalf!As a fellow Hawaiian,I wish you all success.U'a Mau Ke E'a O Ka Aina I Ka Pono![The Life of the Land is Preserved in Righteousness]Mahalo nui!Lisa Alligood aalligood204@gmail.com
