> It's possible to plant big trees but it requires heavy machinery as root are large. Mature trees are also simply expensive by itself, as they require many years to grow. They are expensive to transport, and the transplant frequently fails to take hold, requiring buying another expensive tree, digging up the previous one and replacing it. This makes planting mature tree cost tens of thousands of dollars, compared to tens of dollars for planting saplings.
