Aerating the lawn is an essential step in your lawn care program. This practice involves perforating the soil to improve air circulation, nutrient absorption, and water infiltration, promoting healthy grass growth. In this article, we explain when and why to aerate your lawn, how to identify signs that indicate it needs aeration services, and the benefits of this technique.

Why is lawn aeration essential?

Aeration keeps your lawn healthy by improving air, water, and nutrient circulation in the soil. This helps grass roots develop and grow deeper, making the lawn more resilient to extreme weather conditions, diseases, and insects. Additionally, proper aeration reduces soil compaction, removes excess thatch, and controls weeds and moss.

7 signs your lawn needs aeration

1. Damaged lawn: If your grass looks dull, with sparse and damaged areas, it may need aeration to help roots breathe and develop better.
2. Thatch accumulation: A thick layer of thatch can prevent water, air, and nutrients from reaching the grass roots. If you notice excessive buildup, it’s time to aerate.
3. Excessive compaction: Hard and compacted soil limits grass growth. Frequent foot traffic or heavy activities on the lawn indicate the need for aeration.
4. Poor water absorption: If rainwater or irrigation stays on the surface and doesn’t soak in, the soil might be too compact and needs aeration to improve water infiltration.
5. Slow and uneven growth: If parts of your lawn grow well while others stagnate, aeration can help even out growth by improving air and nutrient circulation.
6. Moss presence: Moss on your lawn can indicate poor drainage and compacted soil. Aeration helps reduce moss by improving soil conditions.
7. Loss of resilience: A healthy lawn should be resilient and bounce back after being walked on. If your grass stays flat or shows visible footprints, it may need aeration.

The best time of year to aerate your lawn

The ideal time to aerate your lawn depends on the type of grass and the climate. For warm-season grasses like Bermuda or Zoysia, it’s best to aerate in summer when the grass is actively growing. For cool-season grasses like Fescue and Kentucky Bluegrass, fall or early spring are the ideal periods. Aerating during these times allows the grass to recover quickly and absorb essential nutrients better.

How to aerate your lawn

Different aeration techniques

• Mechanical aerator: A mechanical aerator removes small plugs of soil, creating holes that allow oxygen, water, and nutrients to penetrate deeper. This method is ideal for reducing soil compaction and promoting healthy lawn growth. It is also known as core aeration.
• Liquid soil conditioner: This involves applying a natural solution that increases oxygen levels in the grass roots, enhancing water infiltration into the soil. Unlike core aeration, which removes plugs of soil, this liquid method penetrates the topsoil layer to create channels, facilitating nutrient absorption and root development. This approach helps reduce soil compaction, improve nutrient and moisture absorption, and strengthen overall lawn resilience.
• Aerator shoes: Aerator shoes are sandals with spikes that you attach to your shoes. Simply walking on the lawn with these shoes can perforate the soil and improve oxygen and water penetration. However, this method is generally less effective for very compacted soils.
• Aeration roller: The aeration roller is equipped with spikes or blades. Rolling it over the lawn creates holes that enhance air and water circulation in the soil. Each type of aerator offers different advantages, and the choice of method often depends on the size of your lawn and the severity of soil compaction.

How to prepare your lawn for aeration

Before aerating, it’s essential to properly prepare your lawn. Water it a day or two in advance to soften the soil, making it easier for the aerator to penetrate. Remove leaves, debris, and weeds to ensure effective aeration. Mark the location of sprinklers and underground lines to avoid damage. Choose the right type of aerator for your lawn size and soil type.

Benefits of proper lawn aeration

• Improved air circulation: Aeration promotes better air circulation in the soil, crucial for root and grass health.
• Optimal nutrient absorption: Aerating facilitates essential nutrient access to grass roots, encouraging healthy and vigorous growth.
• Reduced soil compaction: Aeration helps decompact the soil, allowing water and nutrients to penetrate deeper to reach the roots.
• Thatch removal: Removing soil plugs reduces thatch buildup that can smother grass and hinder growth.
• Disease resistance: A well-aerated soil helps prevent lawn diseases by promoting deeper and stronger root development.
• Better water absorption: Aeration allows more efficient water absorption, preventing surface puddles and ensuring moisture reaches the roots.
• Encouraged root growth: Aeration stimulates root growth, leading to a denser and greener lawn.
• Weed reduction: A well-aerated lawn is less likely to be overrun by weeds, as the grass can grow more vigorously.

How to maximize the effects of lawn aeration

• Choose the right time: Aerate your lawn during the grass’s active growth period, usually in spring or fall for cool-season grasses, and in summer for warm-season grasses.
• Use the appropriate aeration technique: Opt for a mechanical aerator for large lawns and aerator shoes for small areas to ensure even aeration. Prefer liquid aeration (soil conditioner) for sloped terrain or lawns with underground features.
• Follow up with lawn treatment: After aeration, apply a nutrient-rich fertilizer to help the grass recover quickly and grow more vigorously.
• Maintain proper hydration: Water the lawn well after aeration to facilitate nutrient absorption and support healthy root growth.
• Repeat regularly: Aerate your lawn regularly, at least once a year, to maintain healthy soil and promote continuous, robust grass growth.
