Propagating a Tree From a Limb - Part 2
Bob is showing us the developed root ball. The roots have filled the plastic bottle that was put around the limb after the cambium layer was removed and the bottle was filled with growing medium.
Bob will cut below the bottle to remove the limb, then he'll remove the bottle from around the roots and plant the new "tree" in a pot. He'll then support it with rebar driven through the pot into the ground.
