I had a huge pile of plumeria branches after pruning a couple large landscape specimen and they sat for almost a week so I had to figure something out (I didn't yet know that it's supposedly beneficial to let them sit before sticking/propagating them, to let the wounds callous; am unsure if IBA should be used before/after the callous forms..)
I dislike plumerias, they're the epitome of a leggy tree, and was fighting the urge to just throw them away when it hit me- if I propagated them side-by-side (like, 3-10 sticks literally touching each other as they're being propagated/rooted), and then pruned as often as possible/safe, that with a year or two of good growth I'd have something starting to take the shape of a bonsai!
Am I right in thinking this? So far as I can imagine it, the trunks will grow and gain girth while also fusing together, and in the time it takes for them to fuse together to look like a single trunk instead of 3-10, well, that time should be about long enough to have done enough rounds of pruning that there's a significant # of growing-tips coming from that 'trunk' - the trunk-thickness, a 1:6 ratio or squatter with a densely ramified canopy at the right height...am I missing anything? I guess I imagine trees like this:
are created in such a way, like that ^ crepe (I think, am unsure what specie / where I found that beautiful picture!!)
So to that end, here's the start of my first two 'trees' in this manner:
I'm not only hoping for thoughts on whether this will work, or whether I'm missing something (for instance, is my 2yrs estimate for 'kinda looks like a pre-bonsai' on-point? Or more like 5yrs? I guess I'm thinking 1-2yrs is enough that they'd have fused and lignified, it may be a trunk that shows it *was* trunkS, like the crape posted above only far more pronounced, but it'd be '1 specimen' at that point in appearance) Am also hoping to know whether the ones I already made are doomed, as I cut the bottoms of those right before sticking (and treated the fresh wounds with IBA) and supposedly they *need* to callous? I swear I've done regular plumeria stickings, w/o letting them callous, that were just fine.. Also want to find just when I'm supposed to be applying IBA if callousing is a good idea, should it get the IBA when cut or after calloused/ready-to-stick? Lastly, is this a fool's-errand to be beginning in Dec., in zone 9a in FL? We had days in the high 70's last week but are currently in a cold period (it's barely 60deg at 10.30a right now!), I know it's not an optimal time but I've got the material, it'd be nice to have it rooted by spring so it can spend spring/summer growing instead of rooting, so really want to get it going now which leads to my final two Q's
Can plumeria trunk-sticks, without growing-tips, be propagated or do my cuttings need a growing-tip? If I can propagate sticks w/o growing-tips, since they'd have no foliage could I keep them indoors? There'd be enough light for the hormonal/biological cues and a warmer temperature, if they're w/o leaves they don't need real sunlight right, not til rooted and sprouting first leaves'-buds? Because the two I made yesterday were 'trials', I cut & rinsed & stored the rest and want to set them up asap, once I find answers to all my uncertainties here!
Thanks for any help, even guesses would be appreciated for any of my Q's as I just love the idea of this if it'd work as I'm thinking, but it'd be a real PITA to prep, make and wait on several more only to find the idea had some fatal flaw I missed, or that there wouldn't be any semblance of fusing for 3-5yrs more likely, anything like that!!
