Aeration is the process of perforating compacted soil so air, water, and nutrients can reach the root zone. In many Twin Cities yards, clay-heavy soil and freeze-thaw cycles make this essential.
Benefits of Aeration
- Improves root depth and resilience
- Increases water absorption and fertilizer effectiveness
- Reduces surface compaction from traffic and winter snow loads
When to Aerate in Minnesota
Spring and fall are ideal. Fall is especially effective when paired with overseeding because cooler air and warm soil support strong germination.
For thin or patchy lawns, a double aeration plus overseeding program can dramatically improve density over a single season.
