On a June evening at Angle Pond the water goes flat and all of Sandown seems to hold its breath until the peepers start up. Divine Landscaping LLC works the yards around those ponds and the pine-shaded lots between them, where the soil runs sandy and the grass needs a thoughtful hand. Mowing, string trimming, edging along beds and walkways, hauling the clippings off — small tasks in the right order that turn a rough yard into somewhere you want to sit outside. Shade and roots make southern Rockingham lawns a puzzle, and solving one is its own reward. When the last light drops through the pines onto a fresh-cut lawn, that is the payoff.
