Core Aeration: The Fix for Compacted, High-Traffic Lawn Areas

Relieving Compaction Where Kids Play

Bare, hard spots in an Illinois lawn from constant foot traffic are classic compaction. Core aeration is the single best remedy.

Rent a core aerator (heavy, needs SUV/pickup and two people).
Run over compacted areas—machine pulls ½-inch plugs, depositing them on surface.
Leave plugs to break down (5–15 days) or rake lightly.

Overseed bare spots with a traffic-tolerant mix (include perennial ryegrass).
Water daily (10–15 min) until germination.
Transition to deep weekly watering (2 hours).
Fertilize late spring, early fall, late fall (Memorial Day, Labor Day, Halloween).

A dense, deep-rooted lawn handles traffic. Aeration makes that possible. Do it annually in spring or early fall.
