2 years ago I got on brads buds and blooms website went through and ordered a bunch of the cheapest seeds I could find.I know I still have a couple of years to see any blooms. but I would like to see more of them branching out. Is there any suggestions and how this could be done or will that happen over time? I only plan on keeping two of each verity.This is what I got.
6 sarian's curly pink
7 pupukea crepe
5 slaughters pink
5 yellow jack
3 sea breeze
2 courtade pink
4 celandine
2 4308
5 Thornton lilac
2 gigantea

You have a nice collection of seedlings.
Now remember, these are meant to be TREES so they aren't going to bloom until they get a little bigger. Meanwhile, if you cut off the tip they will branch, but you forfeit the possibility of blooms for that year.
So I'm afraid PATIENCE is what you need......
By the way - Plumeria do not come true from seed, so when you say you have '5 Yellow Jack' what you in fact have is 5 SEEDLINGS OF Yellow Jack. They will be different from the parent plant and - this is the good part - they will be yours to name!!
Keep us posted on their progress

Ya I read that thay wouldn't be true to seed. But I also read that can resemble the parent plant. So hopefully they will be close to what I order. Since I still got time before thay bloom I will cut off some the tips and see what happens. thanks for the help.

How much of the tip should l cut off.

Since I want to root what I cut, I always want a 12-18" cutting for rooting purposes. Others will have other criteria.

That would be like cutting mine in half should I let them get taller or just cut them. I would hate to kill them.

If it were mine I would let it get taller. They are just starting to wake up now so you would see a significant change in a month or so. My seedlings are all from Brad Buds and Blooms too and they are about the same age as yours. Some of mine have branched out as seedlings.

Heath, I looked at your pictures again. Your plants are getting a bit spindly at the tip, they might benefit from being stepped up to bigger pots. You'll see them really start to grow when you do that.

Ya I repoted a couple of them.but the problem is I'm running out of room to store them in the winter.when I ordered the seed's I didn't expect all of them to germinate. I'm glad they did but I had to build a grow box for them. witch has work good but if that get much taller they won't fit. What I need is a big greenhouse. I got a bad habit of getting more than I should.

It is a known problem

Boy, is it ever.

The bad part is I'm thinking about ordering some more. I work a second job at a greenhouse.so I could always bring my plant there. But we start running out of room in about the middle of February and March with spring plants.

Were the seeds hard to germinate?

Depending on the variety, and the freshness of the seeds, some are easy to germinate. I have 50% to 100% germination rate on the seeds I bought from Brad Buds & Blooms. That's how I ended up with 60+ seedlings. My DH keep finding pots with seedlings so my item count is sure to grow.

Best time to grow them is late spring or around summer time.

Just about everyone of mine germinated.I also ended up with over 60 seedlings. I think I got a little over 40 left. I gave a lot away.they are fun to grow.

In what medium do you all propagate your plumeria? I have tried and failed in pure perlite. Do you use half perlite and potting soil? Any sand??

Anytime I'm starting seeds I like to use a seed starting mix you can buy it at just about any Home Depot store

Do you cover to increase humidity? Full Sun? I am asking because I am going to plant the newest seeds off my tree soon.

I didn't but I started them in a greenhouse. I used a seed tray with seed starting mix and I just kept them watered regularly and didn't let them dry out.I was surprised on how fast they germinated and how many of them germinated.good luck with yours let me know how they turn out.

I just planted mine in a seed starting mix too just like any seeds. I didn't cover mine and they were initially inside on the window sill of south facing window. I didn't let the soil get too wet but O also misted them so they don't totally dry outl
