Summer afternoons on Bears Bluff Road come with a wall of cloud building out over the water, and the work gets finished before it arrives. Hernandez Tree Service and Landscaping mows and trims across Wadmalaw Island, from the long green rows of the farm fields to the houses set back behind wax myrtle. Grass grows fast in this wet heat — a week is thick, ten days is a hayfield — so the schedule stays tight and the blades stay sharp. Trimming runs along fence posts and mailbox stands where a mower has no business going. When the rain finally breaks, a freshly cut lawn drinks it down and comes back greener by Friday.
