If your lawn is looking thin, patchy, or tired after a hot Iowa summer, Fall is the perfect time to bring it back to life. One of the best ways to do that? Core aeration and overseeding. These two services are essential for homeowners who want a thick, healthy, and weed-resistant lawn.
But what exactly is aeration and overseeding—and why does it matter for your lawn?
What Is Lawn Aeration? 🤔
Lawn aeration is the process of pulling small plugs (or “cores”) of soil out of your lawn using a professional machine. This relieves soil compaction and creates openings for air, water, and nutrients to penetrate deep into the soil—right where your grass roots need them.
In neighborhoods throughout Central Iowa, soil often becomes compacted due to foot traffic, mowing, and even clay-heavy soil types that are common in this region. That compaction chokes out your lawn over time. Aeration gives your lawn room to breathe and grow strong again.
What Is Overseeding? 🌱
Overseeding is the process of spreading new grass seed over your existing turf. After aeration, the holes left behind create the perfect environment for new seed to settle in, germinate, and grow strong.
This is especially helpful for cool-season grasses like Kentucky bluegrass and Turf Type Tall Fescue, which are common throughout Des Moines lawns and thrive when seeded in early fall. If you are looking to purchase your own seed this Fall, this is a great all-around option that you can find at your local Site One Landscape Supply branch in Grimes 👉🏼 Grass Seed
If you go to plant your own seed this Fall, make sure to keep it watered well in order for it to germinate. The general rule of thumb for watering is in the morning, for about 15 minutes, every day, for 7-10 days. If you need more watering tips, check out our blog all about watering here.
Why Fall Is the Best Time in Iowa 🍂
In Des Moines and surrounding cities like Norwalk, Indianola, and Waukee, September is the ideal time for aeration and overseeding because:
- Soil temperatures are still warm, which helps seed germinate faster
- Cooler air reduces stress on both existing and new grass
- Weeds begin to die back, giving fresh seed less competition
This is a critical window—waiting too long can result in poor germination and missed opportunity for thickening your lawn before winter.
The Benefits of Aeration + Overseeding 🌾
✔️ Loosens compacted soil in Des Moines-area lawns
✔️ Increases water and nutrient absorption
✔️ Encourages deeper, healthier root systems
✔️ Helps fill in bare patches and thinning areas
