April in Coventry arrives from the water. The ice goes off Wangumbaug, the shore at Patriots Park turns from grey to brown to the first green, and every lawn in town wakes up hungry. Christians Landscaping meets that season at the root: soil testing before anything else, then fertilizing, aeration, dethatching and overseeding so the turf comes in thick instead of thin. Through the warm months it is grass cutting and weed whacking on a steady rhythm, plus pruning, mulching, planting and shrub removal to keep the beds reading clearly against the lawn. When the ground itself is the problem, they take it further — grading, paver patios, and stone and gravel design and work that gives a yard its bones. The reward is simple and it is visible from the driveway: a lawn with real color and an edge you could draw a line along.
