Best gas-free tools for lawn aeration


The best time to aerate your lawn is during peak growing season because this gives your grass the best chance for a quick recovery. While a tow-behind lawn aerator is a great option, it requires fuel for your tractor. Luckily, there are many gas-free alternatives when it comes to aerating your lawn.

Why do I need to aerate my lawn?

To survive, plants require air, water and nutrients. These elements get absorbed by the plant’s root system. When the soil gets compacted due to foot traffic, yard work, harsh weather and more, it can no longer absorb the essentials your lawn needs to thrive. Without these vital elements, your lawn loses its color and begins to thin. A lawn aerator is a machine or a tool that opens up space in compacted soil so your grass can get everything it needs.

When should I aerate my lawn?

You should aerate your lawn once each year during the peak growing season. But, there are cool-season grasses and warm-season grasses in the U.S. and each has a different peak growing season. The dividing line travels roughly through the center of the country. States above Texas have cool-season grasses and all others have warm-season grasses.

The peak growing season for cool-season grasses is early spring or fall when the temperatures are a little cooler. Warm-season grasses grow the most in the warmer — but not the hottest — period, which is late spring through early summer.

Signs I need to aerate my lawn

If you are wondering how to know if your lawn needs aeration, here are a few key signs to watch for.

  • Discolored patches: Since compacted soil keeps nutrients from nourishing your lawn, one sign you need to aerate is patches of grass that are yellow or brown. Be careful not to mistake the naturally occurring preseason brown of Zoysia grass as a symptom of compacted soil.
  • Thinning grass: Once your soil becomes so compacted that it can’t support adequate growth, your lawn will begin to die off. This is evident in patches of thinning or altogether missing sections of grass.
  • Thick thatch layer: Thatch is a layer of debris that accumulates on top of your soil. Up to about a half-inch of thatch is beneficial to the health of your lawn. However, when thatch builds up beyond a half inch, which can be a result of compacted soil, it can suffocate your lawn. Compacted soil creates a shallow root system on your lawn, which leads to faster-accumulating thatch.
  • Puddles: Water that doesn’t run off your property sits there until it evaporates or gets absorbed by the soil. If puddles linger long after the rain has ended, your soil is likely compacted and cannot easily absorb water.
  • Inability to moisten: If your soil has only two states, dry or puddled, then it’s a sign it is likely compacted. Healthy soil absorbs water, allowing it to stay moist and nurture the root system of your lawn.

Quick test for compacted soil

To quickly test how compacted your soil is, slide a screwdriver into your lawn. If you can drive it 6 inches into the soil, your soil is healthy. If you struggle, it’s time to aerate.
