This is an pdate on some seedlings I spliced together into groups about a month ago. Each were sterilized using 70% isopropyl alcohol spray, as well as my hands, and tools. I sliced a bit off of each 6+ month old seedling at the base and fitted them together. While holding them under firm but light pressure I sealed the cuts with super glue to bind them together.
Then as a precaution I wrapped the base with a thin strip of plastic food wrap (think grafting tape) to keep them from shifting should the seedlings loose or gain moisture as super glue by itself can be brittle and crack. You want it to crack and peel off later but not before the grafts take!
Here's a trio doing great, already healing. So much pollen on everything that I had to rinse it off for the photo! These were put into dappled shade for a week and then eased back out into full sun pretty fast. Here you can see the plastic film around the base that's ready to be removed.
Here's a little older trio of obesum seedlings also glued, plastic already removed. I have pinched the new growth out of the tips to force them to branch more at the tips. They also got a little over dry at one point over the winter as you can see by the yellowed tips on the older leaves. New growth is starting to show. This particular set will get tiped over more and more later and also wired but not while the growth is super fast.
More obesum seedlings, these being a raft of /5/ plants all spliced and wrapped together after sealing with super glue. This one is also some weeks ago and doing great. The one on the far left was dormant but is now breaking new leaves. Later these will all throw random flowers which I can keep if they are very similar, or I can remove the branches and graft whatever favorite flower I feel like onto this joined root stock.
This could also be done to arabicums to produce a monster many branching specimen right away! I'm fairly certain that a number of impressive plants I have seen by 'famous' growers may have been started this way but of course after years, it's hard to tell isn't it?
