The Rainbow River rises from springs just upstream of Dunnellon and runs so clear that tubers drifting on a July afternoon can watch the eelgrass waving beneath them, until the current slips into the darker Withlacoochee at the edge of town. Dunnellon boomed on phosphate in the 1890s, and its historic district still keeps old brick and wood beneath tall oaks and cypress. Tree Trends Inc does lawn care in this river town, where the long summer heat pushes grass to grow nearly as fast as the river flows. Mowing it evenly, trimming it close and edging every border gives a yard the same clarity as that spring water — nothing murky, every line visible. Tree Trends Inc keeps that clarity in the yards of Dunnellon.
