Jacksonville is a working river town at heart, and on a bright November noon the container cranes at Blount Island stand against the sky like a row of giant herons while ships ease down the St. Johns toward the sea. Turf Works brings that same roll-up-your-sleeves spirit to lawn care, and the cool, dry air of late autumn makes this a fine season to be out working a yard. The grass is slowing now, so this is the moment to mow, edge and bring a yard into line before the winter lull. By mid-afternoon the light lies low and honeyed across the grass, and a newly worked lawn looks as squared away as a ship ready to sail. It is practical, hands-on work in a city built on that kind of labor, and the result is plain to anyone walking by.
