A string trimmer attachment assembly for edging a lawn includes a weed trimmer that has a pole, a gear head that is coupled to the pole and a trimming head that is rotatably coupled to the gear head. The gear head is angled between the pole and the trimming head. A rolling unit is removably coupled to the pole of the weed trimmer. The rolling unit is oriented to extend along a perpendicular axis with respect to a rotational axis of the trimming head. Additionally, the rolling unit horizontally orients the rotational axis of the trimming head when the rolling unit is positioned to roll along a support surface. In this way the trimming head is positioned to perform edging along a vertical edge.
