Many people wait until their lawn is in bad shape before aerating – a mistake that can cost them a healthy lawn. Aeration helps alleviate soil compaction, improve water absorption, and promote deeper root growth to keep your lawn lush and green.
But how do you know if your lawn needs aeration? Here, we explain how to tell if a lawn needs aeration and when to call in a professional.
Lawn aeration involves perforating the soil with small holes so water, air, and nutrients can penetrate the grassroots. This method encourages the development of deep roots for a healthier and more robust lawn.
The main goal of aeration is to alleviate soil compaction. Compacted soils occur when there are excess solid particles within a specific volume or space, which hinders the adequate movement of air, water, and nutrients within the soil.
It may be time to consider aeration if your lawn exhibits any of the following symptoms:
One of the clearest indicators that your lawn needs aeration is soil compaction. Compacted soil restricts the movement of air, water, and nutrients to the roots of your grass. This often occurs in areas with heavy foot traffic or where children and pets frequently play.
To check for compaction, use a screwdriver or a soil probe. If pushing the tool into the ground is difficult, your soil is likely compacted and needs aeration.
Thatch is a build-up of dead roots, grass and other organic material that accumulates between the soil and the green grass blades. While a thin layer of thatch is beneficial, too much prevents water, air, and nutrients from reaching the soil.
If your thatch layer is thicker than half an inch, it's time to consider aeration. You can measure the thatch by cutting a small, square section of your lawn and examining the layer of organic matter between the soil and grass.
Water pooling on your lawn after rain or irrigation indicates that your soil might be compacted or that there is excessive thatch buildup. Poor drainage can lead to lawn diseases and drown the grassroots.
Aeration helps improve water infiltration and prevents waterlogging by allowing water to penetrate the soil more efficiently.
Aeration might be the solution if your lawn looks thin, patchy, or is struggling to grow. Compacted soil restricts root growth and nutrient uptake, leading to weaker grass. Aeration encourages deeper root growth and improves your lawn's overall health and density.
Areas of your lawn that experience heavy use, such as pathways, play areas, or spots where cars are frequently parked, are more prone to soil compaction. Regular aeration in these high-traffic areas helps alleviate compaction and keeps the grass healthy.
As with most large lawn projects, it's best to aerate during or just before your grasses reach their peak growth period.
When to aerate your lawn depends largely on the type of grass you have:
Aerating is most effective and less strenuous when the soil is moist from irrigation or rainfall the previous day. Dry soil is difficult to aerate, so some moisture helps. Avoid aerating overly wet lawns; wait a few days for better conditions.
Aerating equipment is available in three main types, from small manual tools to larger tractor-like or pull-behind machines:
Manual spike aerators are suitable and affordable for smaller lawns. For larger lawns, consider renting a plug/core aerator or slice aerator from a local garden center or hiring a professional lawn care service.
