In February the air over Barefoot Beach Preserve runs dry and clear, and gopher tortoises amble across sandy paths between sea oats and saw palmetto on the barrier island along Bonita Springs' Gulf shore. It is the gentle season on this part of the coast, with mild days, cloudless skies and gardens given a breather from summer's heat. Sterling Scape Inc. sees Bonita Springs landscapes through those soft weeks and the hot months after, with lawns mowed, shrubs trimmed and beds tended so each property looks sharp from the curb. Good landscaping here takes a cue from the preserve — a little order, a little wildness, and plants that can stand the sun. A yard finished on a bright winter morning seems to keep that freshness for days.
