On this prairie a grove is a landmark, and Indian Grove has been telling travelers where they are for a very long time. ThatTreeGuy's keeps the lawns beneath and around those old stands of timber, mowing on a steady weekly pass through the Livingston County growing season. Trimming closes up the ground a mower cannot reach — around trunks, fence posts and foundations — and the walks get edged back to a clean margin. In fall the grove lets go of its leaves nearly all at once, and the yards are cleared before wet weather flattens them into the turf. Green, level, and finished at the edges: that is the whole ambition, repeated all summer long.
