Hi, I'm no expert, but seeing as this plant
is going to be remaining indoors, go ahead and transplant them now. It won't hurt them. But like any transplant, we bother the root systems of the plant
, so it will hold back on its growth for a bit, not long, just until it adjusts to its new environment.
As for growing trees
in a grouping or not, I prefer to keep mine separated, always. I have, as you most likely have also, seen the cause and effect of grouped trees
during growth. The weaker will die, or become diseased, which isn't good for any of the trees
in the end.
My own humble sugestion, separate them, give them each ample growing
space and they should thrive under the right conditions.
Nice find btw, to have found a bucket with 8 in it altogether!
