Jacksonville lives with the Atlantic at its back door, and when an October nor'easter parks offshore, salt spray blows over the dunes at Hanna Park and the wind combs the sea oats flat for days on end. Florida Coastal Irrigation and Landscaping works with that coastal character in mind: a breeze that carries salt, sun that flashes hard off the water, weather that changes its mind by the hour. Along a coast like this, water has to fight the wind for every drop, and a well-placed irrigation system keeps grass and shrubs green through the bright, blowing days. The landscaping sets beds and plantings into that wind-scoured light so a yard holds its shape from one blow to the next. When the wind at last swings around and the sun climbs out of the ocean clear and bright, the garden stands back up, green against a scrubbed-clean sky.
