 Finally, container stock. A lot of trees are grown in containers. You want to make sure that there's no roots that are twisting or circling that container. You want to make sure that the roots are removed and looked at during inspection. Pay close attention to large girdling roots. Cut them and remove them. Remember, we need to train the root system of a tree just like we train the above part part. And often that requires parts of the root system to be torn apart in planting.
