Why Spring Aeration Can Sometimes Outshine Fall in the Pacific Northwest
By Cody Cochran | Feb 2026
Hey South Sound lawn lovers!
Here in Lacey and across Western Washington, our lawns take a beating over the winter. Constant rain, soggy soils, and occasional foot traffic (or kids and pets tracking through) can leave the ground compacted and gasping for air by the time spring rolls around. We all know fall is the classic time for aeration—it's when cool-season grasses are gearing up for strong root growth and recovery before dormancy. But here's the thing: spring aeration can sometimes be the smarter (or even better) choice depending on your lawn's condition and what last winter threw at it.
Don't get us wrong—fall aeration is fantastic for long-term health and overseeding success. But in our uniquely wet PNW climate, spring often wins the day for these key reasons:
When Spring Aeration Shines Brighter
Relieves Fresh Winter Compaction: Our heavy winter rains pound the soil, creating tight compaction that blocks water, air, and nutrients from reaching roots. Aerating in early spring (March–April) punches holes right when that damage is most recent, instantly improving drainage and giving roots room to breathe just as growth kicks into high gear.
Preps for Explosive Spring Growth: Cool-season grasses like fescue and rye wake up hungry in spring. Those aeration holes create perfect channels for new roots to dive deeper, leading to thicker, greener turf faster. Sources like Oregon State University Extension note that spring timing aligns perfectly with new root development, helping your lawn bounce back stronger.
Combats Moss and Poor Drainage Early: If moss took over this winter (so common here!), spring aeration after moss control lets air and light reach the soil, discouraging regrowth while promoting grass recovery. It also fixes waterlogging issues before our occasional spring downpours hit.
The Perfect Catch-Up Move: Missed fall aeration last year? No problem—spring steps in as a strong second-best (or sometimes equivalent) option. Many PNW experts recommend aerating in both seasons if your soil is heavily compacted or high-traffic.
Faster Visible Results: With warmer days and active growth ahead, you'll see the benefits quicker in spring—less thatch buildup, better nutrient uptake, and a lusher lawn by summer.
In short, while fall sets the stage for winter resilience, spring aeration is like hitting the reset button after our soggy months. It's especially valuable in years with extra-wet winters or if your yard stays shaded and damp.
