The ground out in the Northwest Woods is sand under an inch of good intention — oak leaf, pitch pine needle, whatever the years have quietly laid down. Soil Inc - Landscaping and Design Company works with exactly that for a living, keeping East Hampton lawns mowed, edged, trimmed and cleaned up season by season. May is when it pays: the grass comes on fast, the beds get cleared, and a yard that looked tired in March suddenly looks like somebody lives there. Growing turf on the leftovers of a barrier beach takes attention rather than luck, and attention is the whole job. Every visit finishes the same way — clippings off the drive, the bed edge sharp enough to sight down.
