Foot traffic, mowing and watering can cause soil compaction and even thatch build-up. When soil is compacted, your grass will have difficulty growing a deep root system. Compacted soil also prevents grass roots from getting adequate water, fertilizer and nutrients. Core aeration softens the soil and creates pockets in the soil to help deliver air, water, fertilizer and nutrients to the turf roots. Aeration also helps thatch build-up and promotes a healthy, vigorous lawn and root system.
What Are The Benefits of Aeration?
- Reduces compaction of soil which allows grass to produce a stronger, healthier root system.
- Aeration opens a path for air, water, fertilizer and nutrients to reach the lawn root level.
- Aeration breaks up the thatch layer and helps return decomposing thatch and its natural nutrients back into your soil. Lawns that are aerated annually almost never develop a damaging layer of thatch.
- Aeration enhances heat and drought stress tolerance.
When Should Lawns Be Aerated?
Annual aeration is beneficial for all lawns. Lawns growing on heavy clay or subsoil, and lawns exposed to intense use should consider two or more aerations each year. Spring and fall are ideal times to aerate.
Why Over seed At The Time Of Aeration?
Over seeding at the time of Aeration is a great way to thicken up a thin lawn or introduce better grass types to a lawn.
Spreading grass seed over a lawn will not give you the desired results. By aerating first, the soil is cultivated, greatly improving the results. New grass will grow in the aeration holes. ‘Tufts’ of new grass will grow out of the aeration holes and then ’tiller-out’ and thicken up the grass in your yard.
