Seasonality in Seattle, WA
Why is lawn aeration important in Seattle?
Seattle's clay-heavy soils compact easily, restricting water and nutrient flow to roots. Core aeration improves drainage and reduces compaction — especially important after wet winters.
When should I aerate my lawn?
Fall (September–October) is ideal. Aeration before overseeding lets new seed fill in over winter. Spring aeration works for heavily compacted yards.
Should I combine aeration with overseeding?
Yes — it's the highest-ROI lawn service combo. Seed makes direct contact with soil through aeration holes, dramatically improving germination rates.
