Front Range clay packs down hard over a winter, and by April a Parker lawn is holding its breath — water beading on the surface instead of soaking in, roots pressed flat beneath the thatch. Highlands Ranch Aerations answers that with core aeration, pulling plugs across the turf so spring rain, air and seed can finally reach the ground. Mowing, trimming and edging round out the work, along with overseeding and the cleanups that follow a long dormant season. It is not a showy service; for a week the yard looks like a field of little dirt cigars. Three weeks after that the color comes in thicker than it did the year before, and that is the entire point.
