GreenPal released information on May 14 about the importance of aeration in lawn care, detailing methods, timing, and potential drawbacks for homeowners seeking to maintain healthy grass. The announcement highlights that aeration loosens compacted soil so air, water, and nutrients can reach grass roots more effectively.
Aeration is a process that involves perforating soil to allow air, water, and nutrients to penetrate the root zone. According to GreenPal, this practice is essential for combating soil compaction, promoting root growth, and improving water and oxygen access. The company said core aeration is usually the strongest option among available methods.
The release explains that there are three main types of aeration: core aeration—which removes plugs of soil—spike aeration—which simply pokes holes in the lawn—and liquid aeration. “Core aeration is what most people think of when speaking about aeration. A lawn aerator with hollow tines reaches about two to three inches down to pull plugs or ‘cores’ of soil and thatch from a lawn to reduce compaction,” according to GreenPal. Spike aeration may worsen compaction instead of alleviating it, while liquid products marketed as alternatives have not been scientifically proven effective.
The best time for homeowners to perform lawn aeration depends on their grass type and region. For example, those with warm-season bermudagrass should consider late spring or early summer; Kentucky bluegrass lawns benefit most from fall treatment. Professionals often recommend aligning the procedure with peak growing seasons so lawns can recover more quickly.
GreenPal advises caution against do-it-yourself approaches without proper training since improper technique or poor timing can stress lawns further or damage underground lines. “It’s wise to hire a professional for aeration or dethatching. If done poorly, both processes can cause a lawn more harm than good,” GreenPal said.
The company concludes by summarizing key points: core aeration remains the most effective method; improper practices risk harming turf health; and hiring professionals helps ensure safe results.
