Cattails stand thick in the shallows around Kraemer, brown spikes rising where the swamp runs right up to someone's back fence. Cattail Lawn Services borrows its name from that border country, and its work lives on the line between wild and tended. Late-summer storms sweep in off the Gulf in the afternoon, drop a gray curtain of rain and leave the grass leaping upward by the next morning. Cattail comes along after the weather, mowing the soaked growth back down and trimming the runners that creep toward the slab and the shed. What remains is a lawn that stops exactly where it should and leaves the swamp to the cattails.
