Aeration and overseeding are essential for maintaining a healthy, lush lawn. Over time, soil can become compacted, making it difficult for water, nutrients, and oxygen to reach the grassroots. Aeration helps alleviate this compaction by creating small holes in the soil, allowing the lawn to breathe and absorb essential nutrients more effectively. Overseeding, done in conjunction with aeration, introduces fresh grass seed to thicken your lawn and improve its overall health and resilience. Together, these processes promote stronger root systems, reduce bare patches, and help your lawn recover from stress, leaving you with a thicker, greener lawn year-round.

Why Aerate Your Lawn?
When you see small cylinders of soil scattered across a lawn and wonder, “What’s that about?”—that’s a sign of aeration. This annual task is key for many homeowners who prioritize a thicker, healthier lawn. Regular lawn maintenance, including yearly aeration, plays a significant role in enhancing your lawn’s health and appearance by allowing nutrients, water, and air to penetrate the soil effectively.

Why Apply Compost w/Top Dressing?
Top dressing with compost is a powerful way to boost your lawn’s health and resilience. Compost enriches the soil with essential nutrients, improves water retention, and strengthens soil structure, promoting deeper root growth and helping your lawn withstand drought, pests, and heavy traffic. It also helps break down thatch and supports beneficial microorganisms, resulting in a greener, healthier, and more sustainable lawn.

When Lawns Need Aeration
The best time to aerate your lawn is during the growing season so that the grass can fill in any open areas after soil plugs are removed. Ideally, you’d aerate your lawn in the early spring or fall.
It may not seem like your lawn is compacted or that it has enough traffic for it to become so, but it happens easier than you may think. Vehicles or small equipment driven on the lawn are obvious offenders, but a lot of playing in the yard or hosting parties can leave your lawn compacted.
If your grass looks stressed and the soil is hard to the touch, or rainwater puddles up where it used to be absorbed, you probably have a compaction problem.
What Do I Do After Aerating My Lawn?
After your lawn has been aerated, let the soil plugs dry where they fall. They’ll break down during the next rainfall or crumble when you mow next. They add beneficial soil and organic matter to your lawn surface.
Right after aeration is the perfect time to overseed and fertilize your lawn. Seeds and nutrients will have direct contact with the soil through the openings created during aeration, giving roots the direct and fresh pathways they need to grow.

Frequently Asked Questions (FAQ)
Why is fall the best time for Aeration and Overseeding in St. Louis?
Fall provides the ideal conditions: warm soil for rapid seed germination and cooler air temperatures that reduce stress on new seedlings. This also perfectly prepares the lawn to absorb the nutrients from your fertilization memberships before winter, ensuring robust spring growth.
How will I need to adjust my irrigation system after overseeding?
Proper moisture is critical. After overseeding, your lawn requires frequent, light watering for the first 2-3 weeks to keep the new seeds moist. This may require temporarily adjusting your residential sprinkler Systems controller settings or consulting with our team about your irrigation memberships plan.
Can this service help a lawn that has severe thatch buildup?
Yes. Core aeration helps naturally break down thatch by pulling soil microorganisms up to the surface. For severe thatch or highly compacted areas, we recommend including the compost w/top dressing service, which accelerates thatch decomposition and soil conditioning.
