Root Balls can be clipped to Root Barriers that provide a vertical blockade to prevent the ingress of tree roots into underground services or features.
Root Barriers are placed as required to protect services or features and then the Trim Root Balls tool can be used to create a clipped ultimate root ball.
After running Create Root Ball, mitigation may be required to limit tree root penetration into underground services or features by the placement of Root Barriers.
Under such circumstances, Root Barriers are placed at the extent of where root growth is acceptable prior to running Trim Root Ball.
