Geodude .. great start .. next early summer you may want to pot it into a grow container shallower bout 3” deep and the size of the desired canopy .. let it grow a season in the pot training the canopy and if possible let it go into the ground for a few years .
The canopy is formed by bending the trunks to form the basic structure . Once the framework is built let it grow wild for a season or two . If enough humidity is present roots will begin to emerge throughout the canopy and trunks.
