1) Prep the soil moisture
Aerators work best when the soil is moist but not muddy. If your lawn is powder-dry, the tines won’t pull clean plugs. If it’s soaked, equipment can tear turf and compact the surface.
2) Choose the right timing for your goal
If your main goal is density and repair, fall aeration plus overseeding is a strong combo. If your goal is better irrigation performance and compaction relief heading into summer, spring aeration can make a noticeable difference.
3) Don’t skip mowing fundamentals
After aeration, keep mowing habits consistent. Sharp blades and avoiding “scalping” reduce stress and help roots capitalize on improved oxygen and moisture movement.
4) Follow through with watering (especially in Caldwell’s dry stretches)
Aeration creates opportunity—watering creates results. The week after aeration is a great time to aim for steady moisture that encourages deeper root growth rather than frequent shallow sprinkles.
5) Consider topdressing or overseeding when needed
If your lawn is thin, patchy, or worn down, overseeding after aeration helps seed-to-soil contact. If the soil is heavy or compacted year after year, a light topdressing can help improve soil structure over time.
