Soil compaction is a frequent cause of turf deterioration. Caused by lawn traffic such as walking and mowing, compaction is greatest in the top 2-3” of the soil. In compacted soil, dirt particles are forced together reducing the area where roots can grow. Aeration, the process of mechanically removing cores of turf, relieves compacted soil by improving the exchange of water and critical nutrients between the atmosphere and the grass’ roots.

For optimal effectiveness, aeration should be performed at least once annually. Spring (between March and May) and/or fall (between August and November) are the ideal times to aerate cool-season grasses, such as perennial ryegrass and Kentucky bluegrass. In drier climates aeration increases drought resistance while decreasing the amount of watering necessary to help lawns remain healthy.

Lawns that receive regular aeration will be greener, easier to maintain and suffer from fewer pest problems and disease.

Benefits of Regular Aeration for a Healthy Lawn

As stated, regular lawn aeration is crucial for maintaining a healthy and vibrant turf on your Brainerd, MN property, and the benefits include the following:

• It alleviates soil compaction, a common issue caused by foot traffic, heavy equipment, and even rainfall, allowing roots to expand more freely and access essential nutrients and water.
• Aeration improves air exchange between the soil and the atmosphere, providing oxygen for healthy root growth and microbial activity.
• The process also enhances water infiltration, reducing runoff and ensuring that irrigation and rainfall are utilized effectively.
• It helps break down thatch, the layer of dead organic matter that can impede nutrient and water absorption.
• Regular aeration promotes stronger, deeper root systems, leading to a more resilient lawn better equipped to withstand drought, heat stress, and disease. This contributes to thicker, greener, and more robust turf in the Brainerd climate.

Assessing Your Soil's Need for Aeration

Determining whether your lawn requires aeration involves observing several key indicators:

• One simple test is the "screwdriver test": try pushing a screwdriver into the soil. If you encounter significant resistance, your soil is likely compacted.
• Another sign is puddling water after rain or irrigation, indicating poor drainage due to compaction.
• Areas with heavy foot traffic or where vehicles are often parked are prime candidates for aeration.
• Despite adequate watering and fertilization, thin or patchy grass growth can signal compacted soil, hindering root development.
• If you notice a thatch layer thicker than half an inch, aeration will help break it down and improve soil health. If any of these signs are evident, your lawn will benefit from our professional aeration services.
