You did an amazing job on germinating all those seeds, Audrey.
I can only tell you what I have seen over the last (almost) year of growing mine from seed. I have had two of the smallish ones catching up with the "Green Giant". Once I re-potted (up-potted) this spring, all have begun to grow faster though. That's probably why I have two do the "catch-up". I kept the Green Giant in the same small pot since it was doing so well. I finally up-potted him a week ago so I would expect him to gain some growth more quickly.
I did not pinch back any of mine. Some have branched but most have not. I am starting to see some (lower) branching here and there, on the bottom half of the swollen trunk. At least I am assuming this is going to be branching. Everything new with these plants is exactly that..........new.
