Can you have two or three trunks spiral around each other without damaging the plant? I just received a Ming Aralia Polyscias bonsai as a gift that has three trunks in the pot (see picture in at Amazon.com under Ming Aralia Bonsai) and was thinking it would be cool to create a spiral (assuming I don't kill the poor thing), but am unsure of how that would affect the growth of the plants themselves. I've been reading two books (The Bonsai Workshop and Bonsai in the Home, as recommended elsewhere on this site), but have not seen it mentioned either way.
Thanks for the input! This site is great for us beginners!
