Core aeration is the single most beneficial service that can be done for your lawn. Aeration involves perforating the soil with small holes to allow air, water and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn. The main reason for aerating is to alleviate soil compaction. Compacted soils have too many solid particles in a certain volume or space, which prevents proper circulation of air, water and nutrients within the soil. Excess lawn thatch or heavy organic debris buried under the grass surface can also starve the roots from these essential elements.
Major benefits of aeration:
✓ increases air, water and nutrient movement to the root zone
✓ intensifies decomposition of thatch
✓ helps relieve soil compaction
✓ stimulates new growth
✓ improves drainage
✓ provides a better environment for overseeding
✓ increase the effectiveness of applied fertilizers and control products
✓ incorporate organic matter into the soil
✓ increases tolerance to heat and cold
All this adds up to a healthier lawn!
Dense, compacted soil (far left) and thick layers of thatch (2nd left) restrict rooting and, in turn, impair the health of the lawn. Compacted soil has no spare space for oxygen, moisture, or roots to move through, thus forming a physical barrier.
Aerating eases both conditions by creating openings in the soil, (3rd right) allowing air, water, nutrients to enter. Microbes begin to flourish and break down thatch. Roots again proliferate, growing thickly and deeply.
