Either rock or wood circle, connected with metal to keep them in a circle. You then fill it with dirt and compact. This allows you to make cheap pillars that can be stacked up to 3 or 4 floors, support a massive amount of weight, so you can fill in between the pillars with whatever you want. You can grow vines down the entire pillar because dirt will be inside of it. Triangle pillars can support more weight. Have to ask someone about how to compress dirt effectively without having to step into concrete, you want to keep it dirt so you can grow things off of it. Though you could connect the trees or rocks with rebar and fill it with concrete if you want.
