The wind through the Golden Gate arrives most spring afternoons around two, and by three every loose leaf in the Marina is somewhere else. Bay Breeze Landscaping plans around it — mowing and edging early, hedge trimming and bed weeding while the air is still, cleanup and hauling before the westerly turns a tarp into a sail. Salt rides in on that breeze and settles on everything green, so the plantings closest to the shoreline get watched a little harder. There is a particular pleasure in a lawn cut clean and a walk blown bare with the bay flashing white behind it. Yard care through San Francisco's windward blocks and the towns just past the bridge.
