>>1043297Bonsai is the typical use for ripping out older plants that have nice trunks. In fact, contacting landscaping companies to get stuff they rip out is great for acquiring excellent bonsai material. The practice helps skip decades of slow growth to get a nice looking trunk.
Basically, just repot them in some large pots like 3-5+ gallon sized pots. That will help them recover quickly. That is standard, until you get the shape you want for the bonsai. Only after that do you actually put them into a shallow bonsai pot for display purposes. Also, they are only ever inside when you are displaying them, like during a party or something. Otherwise, they stay outside.
