The basket is welded together with the welds located to reduce the possibility of fractured welds and, further, reduce both the damage to the structural integrity of the basket caused by the fracture of a weld and reduce the potential for damage to adjacent trees caused by the fracture of a weld when balled trees are stacked together.
