Push a hand into the ground west of Toms River and you find the Pine Barrens underneath — pale sand, quick drainage, water the color of strong tea in the cedar streams out toward Double Trouble. Grass has to be coaxed on ground like that, and lawn advisory service works from the soil up: mowing at a height that shades the roots, edging and trimming to keep the lines honest, cleanups that pull the thatch and leaf mat so air and water can get down. Evening is a good time to walk a lawn here, when the light goes long and the low spots show themselves. Small corrections repeated across a season do more than any one dramatic afternoon. The result is a yard that holds its color through the heat and comes back willing in spring.
