Core AerationBreathe new life into your lawn’s roots!
Why does my lawn need core aeration?
- Compacted Georgia clay soils impede the movement of air, water and nutrients to the grass roots.
- Roots require oxygen to grow and to absorb nutrients and water.
- When compacted, soil contributes to the accumulation of thatch because restricted oxygen levels impair the activity of earthworms and other thatch-decomposing organisms.
- Thatch accumulates faster on compacted soils and heavy clay soils than on well aerified soils.
- When thatch depth exceeds 1/2” it becomes a problem, reducing water movement and encouraging shallow, weak root systems. Thick thatch also can become a home for insects and disease.
- Many people complain about moss growing in their lawns in Atlanta. Lawns that drain poorly due to soil compaction are displaying a “Moss Welcome” sign.
How core aeration strengthens your lawn
How does core aeration work?
- Core aeration involves the removal of small soil plugs or cores out of the lawn. Known as a core aerator, the machine extracts 1/2 to 3/4 inch diameter cores of soil and deposits them on your lawn. Aeration holes are typically 1-3 inches deep and 2-6 inches apart.
- Core aeration is a recommended yearly lawn care practice to control thatch buildup, especially on compacted, heavily used turf.
How will my lawn benefit from core aeration?
- Compacted soil will be loosened, increasing the availability of water and nutrients.
- Oxygen levels in the soil will be enhanced, stimulating root growth and enhancing the activity of thatch-decomposing organisms.
- Your lawn’s drought tolerance and overall health will be improved.
- Your turf will produce new shoots and roots that “fill up” the holes from core aeration, increasing its density.
When is the best time to core aerate?
- The best time to aerate your warm-season lawn (Bermuda, Zoysia) is spring and early summer.
- The best time to aerate your Tall Fescue lawn is in the fall, in conjunction with fall reseeding.
