Ok! I can't procrastinate any more, I must get these seedlings repotted! Can I too know the secret to repotting plumeria without killing them? Advice on the type of mix, watering, fertilizing, staking or any other tidbit of information would be MOST APPRECIATED!!!! These seedlings have done better than any cutting I've ever had and I would like to keep the momentum going.

This is what works for me: I use 50% perlite and 50%miracle grow potting soil (do not use moisture control soil). Hetty mentioned 1 galloon pots for transplanting seedlings. (I grow my seedlings in tiny pots and just gradually move them up 2 sizes bigger if I think the roots need more room or the soil dries up in a day. I have too many, I don't want them to become trees too fast.)

When transplanting seedlings, be extra careful not to disturb the fine roots. If you can transplant with the rootball intact, that would be best. (That's why I grow my seedlings in smaller individual pots so there is minimal trauma when transplanting). I usually dig a hole in the dirt of the new pots first, the size of the hole is bigger than the rootball of the new seedlings, then transfer the seedlings and cover the rootball with dirt. Then I water it thoroughly after applying with 1/4 of the recommended slow release fertilizer and just follow the instruction on when the next feeding should be (usually after 3 months).

I only stake if the seedlings are totally crooked and has not branched out yet . If they have branched out, I let them take their own fascinating shape.

Good luck and post an update. If your weather warms up, gradually introduce them to the sun (partial sun first couple weeks so leaves won't burn then full sun). If your weather this year is warm, You will have 20 small trees by year end.

Thanks Gigi most helpful! I have one problem though. I didn't start them off in individual pots, I should have realized from other trees I've started from seed but I didn't. If I gently wash off the old potting mix and separate them I hope that will not disturb them too much.

Just separate them gently, careful not to disturb the roots too much. Don't wash it off because the roots are really fine and could easily be damaged.

OK thanks Gigi!

Took a while but finally got around to an update on my seedling adventure. I transplanted them but I had to gently wash off the old potting mix to get the roots untangled without breaking too many of them. I potted them in a fast draining medium and stuck them in the shade for a bit and slowly moved them to the sun. May was very hot and dry but come June it's been cold and wet. But the amazing thing is I have not lost one single seedling! They aren't growing very fast because of the cold but they are all alive and well! I had to stake them because they were rocking around in the pots till the roots got going.

Looking very healthy!
