April sets the older streets of Sugar Hill in dogwood white, and every yard under those blooms suddenly wants to look its part. Ken Mullin Landscaping LLC works those spring weeks steadily — mowing as the grass wakes up, cutting edges back to a clean line, trimming the corners a mower cannot reach, and clearing what winter left behind. Slope is a fact of life on this ridge, and mowing a hilly Gwinnett yard well takes a different approach than a flat one. The aim each visit is a property that looks composed from the road and comfortable from the back steps. Petals fall, the season turns hot, and the routine keeps the lawn ahead of it.
