All I did with my seeds is plant one per hole as you describe. Wing out of soil. I kept mine in filtered sunlight, as in under the oak tree out back. I only misted them with a spray bottle maybe once per day to keep em moist. Nature did the rest. Here they are today, about 1 year later...

...sounds like too much water..
I got my first ever Plumie seeds from Brad's and was
impressed at the fresh quality of their seeds.

Here's how I planted mine and got about 90% or more
germination yield (3 out of 5, to 5 out of 5 on each variety):

To check viability and speed up sprouting..wet a coffee filter, place seeds on it and fold it in half, then put in a plastic baggie and hang in a sunny window. After about 24 hours, if the seeds are 'plump' they are viable.
I use a 50/50 mix of Perlite and peat/potting soil, also be sure to use a pot with drain holes. Plant plump end of seed into soil, leaving 'wing' above the soil line. Water well, being careful not to wash seeds loose from the soil. Place in a sunny window or under a grow light.Keep moist, NOT wet. Seeds should sprout in 3-14 days. * Plumeria roots are tender-removing seeds from the soil could break the roots..

***Plumeria are prone to 'root rot'. They prefer dry/barely moist soil. Seedlings can tolerate fairly constant moist soil (providing there's good drainage)until they're established. Keep an eye on your seedlings,they should produce thick stems- if the stems begin to look 'leggy' near the soil, its too wet.
I recently had over 20 3" seedlings get drenched (over 1" rain)in a storm the first night they were outside.The following morning I drained the water from the trays that their pots were in (The 'pots' are simply plastic solo cups with about 5 drain holes in the sides about 1/4" from the bottom)It was cloudy for the next few days, but the seedlings continued to grow well.
Hope this helps!!! Good Luck!

Iv had great sucsess growing plumeria from seed here in Australia.

I have tried many different ways and different growing mediums. Iv found soaking seeds in a seaweed solution for 24hrs gives the highest sucsess rate. They seem to love heat, in a heat box with a constant temp of 30�C 86�F my seeds sprout and open first leaves within 7days but outside with average temp of 25�C 77�F they take 2-3 weeks. Iv found normal potting mix to be just as good as peat and perlite mix at germinating seeds but the seedlings germinated in peat blend grow alot quicker, at 1 month old the difference is very noticable. I use a mild seaweed spray daily i find it to work quite well

I experimented a bit with my first few batches of seeds this fall, most from Brad's, and this is what I concluded: seeds soaked first with Superthrive and Hydrogen Peroxide in their water did far, FAR better than those not soaked in H2O2. The H2O2 seems to help kill off the fungus that causes rot. (If you look back a couple of months I posted a detailed description of my method.)

I started with MG bagged sterile seed starter mix and kept all my seedling containers indoors in a sunny window. I had a 90-95% germination rate with the batches using hydrogen peroxide and a 38% germ rate for those without H2O2. Now, this might have just been coincidence because the batch with rot had a lot of seeds that were not from Brad's, who I think sends very fresh seeds. I also couldn't resist pulling them to check for roots but it didn't seem to do them any harm.

I DO know that I'm never again starting seeds without using the H2O2 soak. I didn't lose a single one after germination, either, and I watered occasionally with water/H2O2 to prevent damping off.

Sure hope you have better luck with your next set, because they are so exciting to watch grow!

I had been told about using packing peanuts to germinate seeds and I had only lost maybe 2 out of 15. The 2 that didn't do anyrthing were also very skinny and I suspect sterile seeds.
All I did was to put the bottom into the peanut and leave the wing end out. I added a few drops of Vitamin B-1 and mixed it with a few inches of water. I added the peanuts, and they floated on the top of the water. Within 4-5 days, they had all germinated. Today I am going to be transplanting them.
