I have so so luck rooting iochromas. Sometimes they'll root just fine and seem to be growing well for a couple months then they'll suddenly up and die for no apparent reason. I've had equal results rooting in soil and water. I have better luck w/o using bottom heat and I don't use rooting hormones. I'll seal the ones being rooted in soil in a large baggie but I open it for a few hours daily or I end up with mold. Good luck.

I have to agree with Karyn on this, bottom heat and take lots of cuttings. I start all ours in soil.

I'm going with just Good Luck! LOL
Mine looked great for a couple of weeks then rotted..Next time I think will try SJN's little humidiy chamber approach.. I knocked off a little branch from a Brug the other day so I figured what the heck.. I put it in a shot glass with just a touch of water and put a juice glass over it and it is thriving... it probably isn't 2" long...also considered pearlite with a little moisture in a baggie .. air it out and blow air in it each day...

Well, I'm going for it tomorrow. I figure I can get 8 cuttings from the limb, some hardwood, some semi-hardwood. I'll put 4 in water, and 4 in a pot with peat/perlite and cover with a mason jar.

We'll see what happens.

Pure perlite; pour boiling water through it to help semi-sterilize it, then cool; seal it *tightly* in a bag or dome; wash cutting thoroughly; mist everything lightly with chammomile tea to prevent fungus; open it only to remist if fungus pops up, maybe once every couple weeks or more.
Keep the cuttings cool, 50's & 60's, no bottom heat (I think Karyn was saying she has better luck *without* bottom heat).
This has worked for me.

Tom I'm guessing you could use Tea Tree Oil as well for a Fungicide??? I have one I could take a cutting from.. I would just love to get one to survive...LOL

Kylie I wonder if it's too strong for weak young cuttings. I know it's advertised as "natural", but so are many other very strong & harmful poisons. Here's a quick quote on caution using it:
--
"Tea tree oil should not be put into the mouth or swallowed. Keep out of reach of children. Even small amounts taken internally can cause severe rash, abdominal pain, diarrhea, lethargy, drowsiness, inflammation of the corners of the mouth, slow or uneven walking, confusion or coma."
--
Chammomile tea you can drink all you want... and it's good for you. :^)

I have better luck without bottom heat. These seem to root better in very cool conditions, at least for me. I had a bunch of cuttings sitting in the unheated greenhouse last fall/winter in a glass of scummy water and those were the only ones that did well for me. The ones I had at home on the seed mat didn't fare nearly as well. I only had a couple out of about 20 that rooted. I don't know if being in soil in temps that cool would work. It was in the 40's to 60's most of the time. I've heard that you can also use cinnamon as a fungicide. I've tried it without success but the plants that I used it on might have been too far gone. I've never tried tea tree oil or chammomile.

I would not use it full strenght..besides I think it stinks..LOL but I do use it diluted alot especially on new seedlings and have never had a problem with burn or anything like that...

just found this video on how to root Iochroma's from cutting
