Island grass has its own vocabulary: centipede that sulks if you scalp it, St. Augustine running thick in the humid ground near Dunbar Creek, zoysia holding tight where the sun stays full all day. Seaside Turf Solutions works to that vocabulary, setting deck height to suit the lawn rather than the calendar, then trimming, edging and clearing the cuttings away. Dawn is the good hour for it, before the heat lifts off the marsh and while the dew still shows the mower's track behind you. Turf held at the right height through midsummer shades its own roots and carries its color into the hardest weeks of August. Lawns are kept around Massengale Park and across St. Simons, Sea Island, Brunswick and Jekyll Island.
