Totally posted on someone's thread on accident (I thought I was on a subforum 🤦‍♀️).

I have a baby plumeria and it got repotted about 2 months ago, it was growing wonderfully with about 5 big leaves and small baby ones starting. I repotted for more room and definitely some of the root got a bit damaged.

The plumeria was ok for a while and then started getting clustered spots on the bottom leaves. Some were silver/black tiny spots and some large round-ish black spots. The black spots would spread and become larger, the leaf then would turn yellow and curl up around the sides, the black would spread along the leaf spine, and finally the leaf started to droop and shrivel. The top leaves and baby ones were fine but as soon as a big leaf would die, the next leaf up would die. Now, even the baby leaves turned brown.

This is my first plumeria so no idea what to do. Neem oil has seemed to not do anything.

Photos show progress of the fungus/disease, missing a photo of the big black spots though. I completely forgot to take the bottom leaf photos, focused on the top newer leaf like an idiot 😅

How big is the pot you have it in? How much are you watering? I ask because you have a glazed or porcelain pot. They don't do very well at losing excess water like plastic or clay. Could easily give you a rot issue. I only have some well established trees in pots like that. Also, did you get this as a cutting? Rooted cutting? Better to let young plants establish a strong root system before trying to up pot for more room. More room means more water held.

Have you already checked to see if you have any pests like spider mites, aphids or thrips? Just wondering as it is that time of the year and have seen them outside in my roses today.

Yes and yes. I got it as a cutting and maybe made the mistake of changing the pot too soon. The cutting had many leaves. When it got repotted, it stopped growing and then started getting black spots on the bottom leaves. Each leaf would die and the next leaf up would get affected.

I still have tiny unfurled leaves at the top which are not yet growing nor are they becoming brown/black and withering so have some hope. The top part of the stem is bright green so at least it is not dying yet.

Should I just let it stay in this pot and hope for the best or should I check the root for rot?

It is purely indoors, I live on a high floor in an apartment. I did not see any bug activity.

My sense is 1) I uprooted too soon (as a previous response also mentioned) and maybe damaged the root, and somehow 2) that gave it some sort of fungus. Maybe the damaged root made it more susceptible.

I do have a drain hole in the pot and only water once every week or even more, so the soil is very dry between waterings and also, the water is not sitting too much. I have a high perlite mix so it is well draining soil.

Maybe the cutting had not callused yet...

I ended up digging it up, all the leaves died one at a time, even the baby ones. The root looked like it was starting to rot or had some sort of disease (it was hard but covered in white stuff) so I just took a cutting of the healthy part and cut out the root. I repotted it and used some rooting growth hormone so here's hoping. Not much else I could do, I think.

I will share an update if that works! In case anyone else has a similar issue.

Before putting it in a pot, wait until it calluses (somewhere between 3-10 days). Then repot it.
