well im sorry i probably wont be of any help but just wanted to say i planted im plumeria cuttings 6 days ago and watered them good but it didnt really dry out till 5 days after. if you think it may be rotting you can take a pin and poke it in that area and if you see white stuff coming out you should be good. or it just might be in shock from being cut and then planted but thats a wild guess. good luck sorry i couldnt be of much help

The orange color COULD be sunburn.

Newly planted UNROOTED cuttings should not be watered until they have rooted. You water them once when first planted and then not agin until roots have formed. If they don't have roots they do not have the ability to take up water or nutrients.

You didn't exactly say what your cutting was planted in but it sounds like it was dirt from the yard with the "Marine Layer" comment. This is not a good choice for a potted cutting. I have used cactus mix mixed with perlite and had great results. Now I only use water rooting as it is much faster.

Hi,
Andi, Marine layer here in So. CA.. means we are having June gloom, damp and no sun until afternoon..in May we were May gray.. ha

Now orange..you got me.. if the branch feels soft, you may or may not have a problem. Pull it up gently and see if the bottom is rotted, will be soft and brownish..If just the bottom, you can cut that off, let it callous, root tone it and try again. But if whole stem..best to show us a picture.
What Mix did you plant in? should be 3/4 pearlite and 1/4 cactus soil. too much soil will rot the plant.

For those who wonder about "marine layer." During May and June in Southern California, the land warms up but the Pacific Ocean is still in the 50's which causes the moisture in the air to condense into a dense high fog. The SW daily wind pushes this fog over the land to the 12,000 foot mountains about 100 miles inland. This creates a gloomy windy day that sometimes burns off after noon and sometimes not at all. This is not a good environment for plumies as the moist air encourages black fungus to sometimes attack new leaves and inflos. Also attempted rooting can be interupted or delayed by the sudden damp cooling that comes at the end of a warm spring. By July, the ocean is warming through the 60's so the May gray and June gloom is no longer created and the skys are sunny and hot. The lesson: do not visit So.Calif in May or June and if you grow plumies, expect some damage from the gray gloom. Bill

Hi Bill,
bravo.. good one. Yes getting tired of grays and glooms.

Its very windy tonight, getting heavy wind gusts, my pansies hit the concrete, gold lily, darn it

Thank heavens today I decided to plunge 4 of my canned plants into my plumie garden, or over they would have went with damage, per Tony's suggestion. Plunged singapore, puu kahea, jeannie, and pacific pearl. Rest have in a corner..Tomorrow, will put more of the cans in the ground. Never wanted to do this, but we have some wicked winds.
Feel that perhaps watering will go straight through, and keep them cooler for the summer. hope.

Thanks for the input! Actually I planted in cactus mix, but seeing the reluctance of the cactus mix to dry out I will mix it with pearlite when I try it again. I did poke around and indeed the stem was rotting, so I cut it off and now it is callusing. I think I will try water rooting it when it's ready. Also I brought the other two inside and put them on a heat source where they are already much happier! And as a consequence, so am I ... Thanks again, all this information is wonderful.
