Community Tips

TipKasa Team

Aerate when soil is moist but not waterlogged—ideally 1-2 days after rain—as this allows the machine to penetrate 2-3 inches deep and extract proper plugs rather than merely scratching the surface. Core aerators like the Agri-Fab 45-0525 ($40-60 per day rental) work most effectively under these conditions.

WarningKasa Team

Never aerate over buried utilities without calling 811 first; most homeowners underestimate the depth of gas lines, electrical conduits, and irrigation systems, which typically run 6-12 inches below grade and can create expensive and dangerous situations.

ExperienceKasa Team

Plan to overseed immediately after aeration while soil plugs are still breaking down, as the exposed earth and disrupted thatch create ideal seed-to-soil contact; a quality perennial ryegrass blend like Scotts Premium Grass Seed ($25-40 per 5,000 sq ft bag) germinates 40% faster when applied within 24 hours of aeration rather than weeks later. ---
