Kendall County is not flat, whatever the highway makes you think. The ground lifts and settles in long low swells toward the Fox River valley, and every lawn sitting on those slopes wants something a little different. Green Hill Landscaping LLC works those Plano yards from the first green push of April, when the grass comes back faster than anyone expects, on through the heavy growth of June. Mowing, trimming, keeping the turf even where the grade rolls away from the house — it is patient work, and it shows. A yard cut well on a rising lot catches the late light all the way down.
