I would prune them at least half way, should force out branches at leaf junctions. Re pot into a gritty mix in a pot with holes, please don't use see through plastic this time though, regular plastic is fine, terracotta good, but needs experience to some degree till you adjust to watering them. Pot doesn't need to be that much bigger in diameter than current ones, but set them higher up in the pots. You could use half pots which are nice, so would need to get wider ones than if they were regular pot type.

I think it depends on what you want them to look like. They could be wired and bent around to become bonsai such as semi-cascades, or braided together, or simply cut down almost all the way to the caudex to make them throw new branches down low, or as mentioned prune only part way down to start branching somewhere mid level.

My best suggestion would be to go looking around the internet for photos of plants of the same basic kind (obesums I assume) you like the shape of and then we can better advise you on how to start getting them in that direction. Do you want to make these into curvy bonsai, or bushy, or looser and lightly branching? Also think about size. Do you want to keep them around a foot tall, or two feet, or do you want to produce large specimens for big impact?

Thanks greenclaws. I might try pruning one or some of the seedlings halfway. These plastic cups which I've made holes at the bottom are naturally a temporary thing. Wasn't exactly thinking of pots until about 30+ seeds germinated, then it was whoops :) Will be slowly re-potting all of them soon.

Hi Hyn Patty. It's my first time growing these so it didn't strike my mind that I would have to think about how I want the plant to look like at say 3 years old when it is just 6 months old. A revelation for me. I'll look around on the internet but really, any suggestion is fine with me, whether it is for bonsai, looser or lightly branching. Something to get this newbie started would be great :)

Thanks Hyn Patty. You've given me some ideas. I guess I will just have to experiment and hope they'll grow into some interesting shape. Good luck with yours.

Jo, if you prune now, the caudex will grow faster.

Marie

What evidence do you have that it is the case, Marie?

Hyn Patty, when I prune my plant, it puts all energy to grow on the caudex. (my opinion only)

Marie

Jo,

You could prune them, but if you choose to do so. Prune low down, as with the thinner base. A multi stemmed plant be appealing without having a larger caudex. They should go into slightly larger pots/cups 1" either side of caudex. By reducing the height it will assist the plant to produce laterals and the caudex will become larger as predisposed by it's genetics. Each plant will be different.

They will require good light for a minimum of 8hrs. (Sunlight) and warm temps.

Rick

Thank you, Marie. Your opinion still counts! I simply hadn't read anything else documented on that but I have read that elevation and dryness effects caudex sizes in species plants in the wild. Those tending to lower elevations having much less than those at higher.

Thanks Rick for your comment. Will definitely try pruning low, but I suppose I should do it after I re-pot the seedlings so that all the growing can happen in their new pots.

No problem with light and warm temps where I am.
