Balazs,
I would put the one with the small root back in the soil and let it continue, as some cuttings take alot longer to root than others. The ones with the brown soft parts should be cut above that area until it is good tissue of the plant.
You will be able to tell. Put some root tone with a fungicide in it on the cutting, let it dry for several days/week, and then replant. I don't know where you live, so I don't know how much warm weather you have left before plants normally go dormant. In other words you may have to wait till next season to root the others. Depends on your location on the planet. Hope this helps you some.
Take care,
John

John,
I live in Hungary, so I haven't got any time outdoor, but I can put the cuttings in a heated room (75 F 0-24), next to the window.
And what about, if i would like to wait till next season? How can I store the cuttings more than a half year?

Balázs

Balzas even though the room is heated you want additional bottom heat to help promote rooting. Without it you will run a greater risk of the cuttings rotting again. I think it is possible to store the cuttings but I've never done that.
Karyn

Balazs,
I don't know if cuttings will stay viable for more than a few months. Alot of people on the forum advocate the bottom heat when trying to root. So, you may be able to root them during the winter in the heated room, with a heating mat underneath it. Hopefully the window you speak of gets quite a lot of sun during this time as I think sunlight is a must for rootings to be successful. Also, I am NOT an expert on rooting plumerias, but hopefully what I am telling you is very close to correct. But if the cuttings won't last more than a few months in storage, you may as well give it a shot at rooting them. You have nothing to lose. Hopefully someone else will add to what I have to say. Best of luck.

John

Balazs,
Hi again! You have received some good advice in the posts above. To root indoors you must have some bottom heat. A commercial grower in my area has hot water circulating under his pots to keep the soil temperature about 80F. There are heat mats you can buy that will do the same, but many do well with a human heating pad with plastic on top to keep it from getting wet. Others have used an old waterbed heater under a layer of sand in a wooden tray. Some keep the cutting in the kitchen near a heat source.

Last winter I got a heat mat that came with a metal screen to keep the pots about an inch above it. After getting nowhere rooting that way, I put the pots directly on the mat and they rooted very quickly. So, bottom heat is essential for rooting.

I have heard of cuttings being viable after a year, but I believe a lot depends on the size of the cutting. I would be concerned about the cuttings that have already rotted lasting until next spring. You have nothing to lose by trying to root them over the winter.
Mike

Thanks for all!

The main thing is -like you said- I have nothing to lose.
The heat mat: below the window, there is a heater radiator. In winter hot water circulate in it, and warm up the air, and the warm air is move up... My plumies will be above the radiator (6-7 inches) so it will be working as a heater mat. At least in my opinion.
But a little problem: The heating season usually begin about oct. 15, so I have to wait some week. Should I leave my unrooted cuttings in the pots untill the heat begins?

Balazs

If your daytime temps are warm, you can put them outside in their pots on concrete, stone, or gravel to provide some bottom heat. Then bring them inside if it gets too cool at night.
Mike

It's difficult to put out, and bring inside the cuttings every day. Because I live in a flat, without garden, or something like that. My plants are out at my grandmother's house. I haven't got any time for go out in morning, and came back, and in the late afternoon again.
Now the daytime temp. is OK (today: 84 F) but the nights gets colder and colder. (53-56 F)

Yes, moving them in and out won't work with your situation. So the best choice seems to be the heater near the window. It gives you the best chance of success over the winter. Good Luck.
Mike

Oh, my stupid stupid head!!!
When I planted my cuttings I donÂt know anything about FUNGICIDE. (and still donÂt know too much.) So I thought itÂs not important and only used rooting hormon. And now I reading on plumeria101.com about stem rotÂ
What the hell is the fungicide? ItÂs an collective noun? A mushroom killer (not what you eat :). But i donÂt know the equivalent word in English. Wish I could speak English)
In here we use numerous Âmushroom killer" on almost every plant: on fruit trees, grape, flowers (roses, leander etc.) evergreens, vegetables to keep them healty, and help to resist against diseases.
Maybe fungicid = Âmushrooom killer" or in hungarian: gombaölõ???

balage..I hope this doesn't make your head hurt any more.

Fungicide
From Wikipedia, the free encyclopedia
A Fungicide is one of three main methods of pest control- chemical control of fungi in this case. Fungicides are chemical compounds used to prevent the spread of fungi in gardens and crops, which can cause serious damage to the plants. Fungicides are also used to fight fungal infections.

Fungicides can either be contact or systemic. A contact fungicide kills fungi when sprayed on its surface. A systemic fungicide has to be absorbed by the fungi before the fungi dies. One example is the QoI.

It is used in agriculture to avoid fungus growth because this can harm profits, Corn is often sprayed with fungicides and some fungicides are genitically modified to make sure that they get to work straight away by damaging all of the fungal cells.

In contexts other than agriculture, the term antifungal is often used for similar compounds.

Fungicides can also indirectly be harmful to human health as the cultivated crop is consumed and it can cause irritation as well as many symptoms such as headaches, diarrehea, damaged organs as well as severe disorders and maladies related to the nervous system. It is also a hazard to ecosystems as it can run off and can contaminate water bodies and as it bioaccumulates it can be increasingly toxic to living organisms in the ecosystem.

Here is a link that might be useful: online encyclopedia

Balage many of the rooting powders sold in the US have a fungicide already mixed in. I've also used a rooting gel that didn't contain a fungicide and didn't have any problems with stem rot. If your cuttings are growing and looking healthy I wouldn't worry.
Karyn

PS: John, fungal infestations, especially Black Spot are the reason why I refuse to grow roses here. I have problems with powdery mildew on many plants also. Our cool moist nights are the perfect growing conditions for fungus, yuck!

I've never had much luck with roses either. Seems every bug in Florida likes them for lunch.

John

Thanks the link John!
There is no hungarian version about fungicide, but now I understand on the whole.

Karyn!
Three cuttings hasn't got roots yet, and they show the symptom of the stem rot: soft stem. I'm afraid to kill them.
And if I recut the rotted parts, what kind of fungicide that I have to use? I mean, here is so much of fungicide. (I don't know the correct number, but I'm pretty sure more than 2-300) There is powder and liquid, contact and systemic with different effective substances and different names for example: Topsin, Merpan, Fundasol etc...
Which is better? The contact or systemic? I think contact will be working.
And how can I use it? If it's a powder just mix with rooting powder? Or how?

I have no idea. If you can find a powdered kind that you put directly on the plant without diluting it maybe you could mix it with the rooting powder. I'm going out tomorrow to make one last attempt to find B1 before resorting to mail order. I can pick up a pack of rooting hormone/fungicide mix and mail it to you (unless there are some weird restrictions). It's cheap, only a couple US dollars.
Karyn

Your welcome balage. Sorry they didn't have Hungarian, but glad you understand. I am including pictures of what I use. Don't know if you can get this in Hungary or not but you can see the ingrediant.

Ok this is Susan Va... Ok I have several cuttings outsid and at night now it getting cooler... high to mid 50's then some high 50 to mid 60's So if I am reading correct I should bring my cuttings at night and put on a heating pad or where would you get one of the pads you all talk about and a ball park figure of how much???? I have seeds under a 40 watt bulb for the last several day and also one of the cuttings the dog ate and go very sick I might add... Does Root tone always have the fungicide in it??? So much to learn Dont know how much more this brain can keep in... I really would like to know where I could get a heat mat... I am going to look that up or take a drive on Friday to Greensboro to look up there my town is just a little thing... I dont know if I am cut out for this seeds and rooting thing..LOL I really just dont know when to water the cutting.. I am afraid I am going to kill them... I am going to grow my next set of seed in perlite like somone form this forum told me to...
Thank you any help..
Susan,Va

Thanks the pictures John!

Karyn!
That's very kind of you. I don't know about any restriction which concern to importing rootone. But it doesn't mean there isn't...
But I know surely : importing plumeria cuttings is not possible. Unless you have a special import permit. Theoretically...
Cause when I got my cuttings, there was no import permit, or any other permission. Jennifer (from MauiPG) just send simply with Fedex, and there wasn't any problem.
So it's your decision. If you decide to send rootone, I will very grateful to you. My e-mail is: csiszi.j@tvnetwork.hu

Suzan,
I read on the forum here at one time or another that someone got a heating pad at Target stores for around $10.
Good luck,
John

Balage I sent you an email but thought you might read this first. I picked up a packet of the rooting hormone w/fungicide for you and just need your address. I still haven't found any B-1 for me around here: (
Karyn

Karyn,
I just returned from the nursery by my house and the guy there said super thrive has B-1 in. It says on the bottle 50 vitamins and hormones. I kinda figured B-1 had to be in that 50 somehow.

Take care,
John
