Top 5 Signs Your Lawn Needs Aeration Before Fall

TL;DR

If your grass is thinning, patchy, retains water, feels spongy underfoot, or doesn’t respond to watering or fertilizing—even when you’re doing everything right—it’s probably time to aerate. Lawn aeration relieves soil compaction, improves drainage, and allows nutrients and water to reach the roots where they’re most needed. Early fall is ideal for cool-season lawns. Supreme Lawn and Landscape provides professional aeration and overseeding services to restore your lawn’s health and appearance.

Fall is a crucial time for lawn care, especially if your grass has endured summer stress. Lawn aeration is one of the most effective ways to revitalize compacted soil and prepare your yard for a healthier spring.

1. Your Lawn Is Thinning or Bare in Places

Noticeable thinning or patchy grass is often caused by compacted soil preventing roots from spreading. Aeration allows air and nutrients to reach deeper soil layers, encouraging stronger, denser grass growth.

2. Water Pools After Rain or Irrigation

If you’re seeing puddles after a light rain or routine watering, your lawn likely has poor drainage. Compacted soil can’t absorb moisture efficiently, leading to runoff and root rot. Aeration alleviates this by improving soil structure.

3. Spongy or Thick Thatch Underfoot

Excess thatch—a thick layer of dead grass and roots—blocks nutrients from reaching the soil. If your lawn feels spongy, it may be time for aeration to help break up thatch naturally and promote microbial activity.

4. You Struggle to Push a Screwdriver into the Soil

Try the screwdriver test: if it’s hard to push a 6″ screwdriver into the ground, your soil is likely compacted. Aeration relieves this, allowing better root penetration and nutrient absorption.

5. Your Lawn Isn’t Responding to Water or Fertilizer

When grass doesn’t green up despite consistent watering and fertilization, compaction might be the issue. Aeration helps these inputs reach the root zone where they can make an impact.

Why Aerate Before Fall?

• Boosts Overseeding & Fertilization: Fall is the perfect time to seed and feed cool-season lawns. Aeration improves soil-to-seed contact and nutrient uptake.

• Reduces Weeds Long-Term: A thicker, healthier lawn post-aeration helps crowd out weeds naturally.

• Encourages Deep Roots: Aerated soil fosters deeper root systems, which improves drought resistance and winter hardiness.

For warm-season grasses, aerate in late spring or early summer instead.
