Just let the container air out overnight, a chamomile tea solution, (1-2 tea bags per gallon), will also get rid of that.

Looks like you have some growing 8)

Knnn,

Any idea what that is? Do you think my soil to to moist?

Just a fungus/mold of some sort, (high humidity, just the right temp & lack of air flow)

From my experience the white stuff is pretty harmless and easy to control, usually just letting things air out a bit takes care of it. The Chamomile tea solution is a mild fungicide which will also kill it. The green and black molds are a bit nastier and require heavier treatment, ( Daconil,etc) You may want to take the lid off for a couple hours each day just to let the very top dry out.

PS - A germinating medium with an organic base will almost always have these spores present in it.
You may want to think about switching to a sterile medium like Perlite, Vermiculite, or some of the other non organic mixes.

I second the Perlite and I second and third and forth the Vermiculate. I am a big fan of vermiculate.

I will look for that next time I am out. Do you think it will hurt the seeds if I replant them?

Moving the ones that have germinated into deeper containers would probably be a good idea. Something at least 6"/15cm deep ( styrofoam cups work good 🙂

Knnn,

Do they still need to be kept really warm once they germinate? Reason I ask is because once I remove them from their little greenhouse I have no way to keep them really warm. I am using Christmas light under the containers now and it seems to be working well.
Any ideas?

😆

After germination they really don't need to be kept at a higher temp. A warm spot in the house would do.
Also indirect bright light for the first leaves / no direct sun ( Most Palms start off as an understory plant for 2-3 years)

Good Luck with them !!

Knnn,

What is a understory plant?

Also, a quick question, I planted my T. FOrtunei yesterday. Tonight (currently) it is 6c. It is supposed to rain...a lot...tomorrow. I went out and wrapped christmas lights around the base and middle shoots. DO you think I overreacted?

Understory in the sense that it is under the canopy of other foliage. In habitat, most palms will take several years before they grow into a full sun position.

DO you think I overreacted?

Not at all ........It will probably be the middle of May before I feel safe enogh to put all the Winter protection stuff back into storage 🙂

Here is what I do, and it seems to be working well, but I would listen to KNNN before me 😆
After they pop, I take another container (3" containers are what I use to germinate) and put that one upside down, on top of the one with the seeds. This gives the radicle 3" more to grow while still giving it a greenhouse feel. I also leave it on bottom heat.
After the radicle reaches the top of the container, it is at least 6" tall, so I pot them in styrofoam cups and put them in a sunny spot in the house (take them off bottom heat). I leave them there for about a month. Then I put them out in the greenhouse.

Thanks Kansas!!!
