Why, When and How to Aerate Your Lawn

How important is it to aerate a typical home's yard?

Aeration is only important if your lawn has regular, heavy foot traffic. Otherwise, it is not necessary for the average lawn.

Can you walk on your lawn after aerating?

Yes, you can walk on your lawn after aerating.

Should I leave plugs on my lawn after aerating?

Yes, you should leave the soil plugs on your lawn after aerating. These plugs will eventually disintegrate, and the nutrients they contain will return to the soil. This can help to promote healthy grass growth.

What does aeration do to a lawn?

Aeration temporarily improves water infiltration and relieves compaction. It creates small holes in the soil that allow air, water, and nutrients to reach the root system easily.

Aeration is an important process that can improve the health and appearance of your lawn. Aeration works by creating small holes in the soil that allow air, water, and nutrients to penetrate easily. This process also relieves soil compaction, which can occur over time due to foot traffic and equipment.

While aeration can be beneficial, it is important to note that the benefits are only temporary. The soil will become compacted again unless the soil is improved with organic matter or foot traffic is reduced. Therefore, it is only important to aerate a lawn that experiences regular, heavy foot traffic.

Q. Why should you aerate your lawn?

A. Aerating your lawn can help to relieve physical compaction caused by foot traffic or heavy equipment. Relieving compaction can improve the overall health of your lawn by allowing water, air, and nutrients to reach the grass roots.

Q. How frequently should I aerate my lawn for proper growth?

A. You should only aerate your lawn as needed. Over aerating can lead to diminished soil quality. Before aerating, visually inspect your lawn for a noticeable difference in turf quality, or consult with a professional.

Q. What is the best way to aerate a lawn?

A. The best type of aerator for relieving compaction is a core aerator, also known as a plug aerator. This type of aerator removes small plugs of soil from the lawn, allowing for better air, water, and nutrient flow.

A spike aerator, on the other hand, does not relieve compaction but can improve drainage temporarily. It also causes less damage to the soil and existing grass. It is important to choose the right lawn aerator for your specific needs.

Q. What is the easiest and most effective way to aerate a lawn?

A. The easiest and most effective way to aerate your lawn is by hiring a lawn aeration service. Core aerators are heavy and difficult to maneuver, especially if you have obstacles in your lawn. Ride-on aerators are expensive and not always practical for smaller lawns. If you have a big yard, you may be able to rent a ride-on aerator in your region.

Q. What are our recommendations for lawn aerating?

A. Our recommendation is to use aeration as a tool to improve grass seed germination. Lawn aeration can also be used to incorporate fresh compost into your soil. This will promote a healthy lawn and improve grass growth over time.

Q. What are the cons of aerating?

A. Over aerating can lead to diminished soil quality over time.

Liquid lawn aerator

Liquid aeration products are often marketed as a miracle solution for lawn aeration without the need for physical equipment or labor. It’s important to understand that these products are essentially surfactants that improve water infiltration but do not address soil compaction. Despite claims made by manufacturers, liquid aeration products cannot physically break up the soil. Breaking up hard soil requires core aeration.

In fact, a study conducted by the University of Arkansas found that liquid aeration had little to no impact on soil compaction or root development in turfgrass. While liquid aeration products may provide temporary benefits, they should not be considered a substitute for core or plug aeration.

Chemical compaction

Chemical compaction refers to soil compaction caused by excess sodium. Excess sodium causes clay particles to disperse, resulting in compacted soil. This is common in arid regions or areas with high levels of sodium in irrigation water.

To address chemical compaction, soil amendments such as gypsum can be used to replace the excess sodium with calcium. This helps to separate the soil particles and improve the soil structure. A study published in the Soil Science Society of America Journal found that gypsum applications were effective in reducing soil dispersion and improving water penetration in sodic soils. Gypsum will only be effective in sodic conditions, it is important to conduct a soil test before considering gypsum.


Are you trying to figure out the optimal time to aerate your lawn in Ontario? We recommend choosing spring or autumn when the soil is moist, but not waterlogged. If you’re uncertain about your lawn’s specific requirements, an honest aeration service can provide helpful guidance. Aeration can significantly enhance your lawn’s health and appearance, but it’s essential to use it sparingly.
