I am a newbie at rooting Plumerias. I have a nice cutting that I planted in a pot in mid-Feb which is around my pool and getting full sun (though through a screen). Temps here in SW Florida have been 70s/80s during the day and 50s/60s during the night. I've read that they will root when temps are over 60 so I know the temps have been inconsistent. It's been 6 weeks though and still nothing. I can't see if its rooting since my pot is black plastic and people say not to disturb the roots. It does have closed green/reddish claws at the tip (see pic). I've read about plumeria rot and although the stalk feels solid above the soil, beneath the soil, it feels there is a separation between the "bark" and the "pulp" inside the stalk and the pulp inside seems less. It doesn't feel squishy wet though. Not sure if I should give it more time or dig it up and assess the end (and risk disturbing roots)?

I guess no one saw my post or doesn't has any advice. But I just wanted to give an update in case someone does have a suggestion!

Update: it's been a month now and leaves are forming (not completely open yet but extend 3 inches from top) but the stalk is still soft at the base and seems to be moving up a little further. I did the pin test - stuck a pin in the stalk closer to the top and got white fluid. When I stuck a pin in the softer lower area, I had to squeeze a lot but got an amber colored fluid.
My question is, if this is root rot, would my leaves be forming seemingly so well? And if I dig it up, cut off the rot and start all over, will the new leaves die off until new roots form?
Thx for any response.

Stem rot perhaps.
I rooted several Plumeria while I lived in Florida. Did you let the fresh cut ends callus over?? They will root better and safer if that fresh cut end dries out forming a scab.
Once hardened off, I never had trouble rooting them. Some took longer then others.
BUT I rooted them in subdued light, not full sun.

Hi BigBill. Stem rot is what I suspect but it's odd how the new leaves keep opening. I'd think somehow the leaves would stop opening at this point.

I bought my cutting from a plumeria nursery in Feb. The end was calloused over when I received it. I planted it in a 50% perlite/50% soil mixture. Watered it thouroghly the first day then left it alone (even taking it in if it rained so it wouldn't get wet). Spritzed the claw leaves. Watered very very small amounts only when the soil was bone dry. Put in full sun on screened pool deck.

The supplier told me to plant it right away in mid Feb. our daytime temps were nice - usually in the 70s/low 80s. But nights were dipping into mid 50s. So maybe it was planted too soon and sat in the soil too long before the temps were right for it to root.

It could be. It rotted through no fault of your own.
I always started my cuttings in straight Miracle Grow potting soil. One or two out of twenty would fail to root. I would water a bit on planting. Keep them fairly shaded and only watered when the soil started to become noticeably dry. No fertilizing, no misting.
You are living in one of the most humid places on Earth. There is nothing to gain by misting.

Could you post an updated picture? And scrape some soil away from the base of the stem.

Yes, here are a few pics. See what you think...

It looks OK and you have new leaves growing which is a good sign. Keep an eye on it!

Hows it doing now ??
