If you have high traffic areas or heavy clay soil, you'll want to air them out every year. If you have sandy soil or your lawn grows well, you can air it every 2 to 3 years. Aeration is one of the best ways to thicken grass and improve the effectiveness of normal irrigation, fertilizer and pest control programs. The easiest way, and one that doesn't require any special equipment that you don't already have, is to take a regular garden fork and walk up and down in rows drilling holes in the grass approximately every four inches.
We'll dive deeper into what aeration means, why it's necessary, and how to start aerating for a healthier lawn. Once a year is usually sufficient in most cases, and for healthy lawns that receive regular maintenance and work well, it may be sufficient every two to three years. Although in the short term you'll end up with small holes in the grass and plugs of soil strewn across the grass, aeration will improve the appearance and health of the grass. By aerating the grass, holes are created for the roots to grow, allowing the grass to grow stronger and healthier.
They are special shoes with spikes on the bottom, and all you need to do is walk up and down the grass to air it. The best time to aerate a lawn varies depending on the type of grass you have and the climate in your region. Aerating your lawn regularly will reduce the hassle of renting and using a brushcutter or electric rake. Although there are other aeration methods (such as aeration with picks, blades and liquids), core aeration is considered the most legitimate and popular aeration method among homeowners and lawn care professionals.
Generally, lawn health and other signs, such as soil compaction, water buildup, thick straw, and uneven grass growth, will tell you when your lawn needs to be aerated. After that burst of growth during the spring growing season and after surviving a hot, humid summer, your lawn has been beaten up. As a result of foot traffic and normal daily activity, grass soil can become compacted, preventing oxygen, water and nutrients from reaching the roots. Constant aeration keeps the grass healthy and green, preventing the grass from being dry, unsightly brown stains and future lawn problems.
