April in Woodridge is heavy clay and heavier rain — the ground under these subdivisions holds water like a cupped hand, and turf comes out of winter tight and airless. Plugginalawn's answer is written in the plugs themselves, pulled in dotted rows across a yard so the soil can breathe and water, seed and root have somewhere to go. Around the aeration comes the rest of it: overseeding, mowing, edging, and the spring cleanup that clears away what the snow pressed flat. From the high ground at Greene Valley the village reads as one long canopy of trees, and every green rectangle tucked under it started as somebody's ordinary lawn. Aeration and lawn care for Woodridge, Downers Grove, Lisle, Bolingbrook, Darien and Naperville.
