Lawn aeration
Also known as: core aeration, lawn coring
Removing small plugs of soil to relieve compaction, improve water and nutrient penetration, and stimulate root growth. Typically done annually in spring or fall.
Lawn aeration uses a machine — typically a core aerator — to extract small plugs of soil and thatch (1/2 to 3/4 inch diameter, 2-3 inch deep) from the lawn at regular intervals. The plugs left on the surface break down within 2-4 weeks, returning organic matter to the soil.
The core extraction relieves soil compaction (which restricts root growth and water infiltration), reduces thatch buildup, improves drainage, and creates channels for fertilizer and overseed to penetrate. Most cool-season grasses (fescue, ryegrass, bluegrass) benefit from fall aeration; warm-season grasses (Bermuda, zoysia, St. Augustine) prefer late spring to early summer.
For lawn-care operators, aeration is high-margin recurring service. Equipment investment ($1,500-$8,000 for walk-behind, $10,000+ for ride-on) pays back quickly. Common upsell pairings: aeration + overseed + starter fertilizer (single visit, three line items). Customers typically pay $100-$250 per residential aeration visit; 2-3 hours of crew time per average yard.
