For Improved Grass Health
It’s a safe bet that the most beautiful lawns you see are ones that are aerated (and for cool season lawns, seeded in the fall). For may soil types, compaction is a problem that prevents oxygen, water, and nutrients from reaching your grass’s roots. This causes shallow roots and makes grass more susceptible to drought, heat and disease stress.
Depending on the equipment used and exact technique, may also be called aerovation or aerification.
Foot traffic, regular mowing, and even rainfall are constantly compacting your soil.
Aeration is performed when your grass is actively growing, usually spring and/or fall for cool season lawns, and summer for warm season lawns.
Spring and Summer Aeration prepares your lawn to respond better to spring and summer nutrient applications, and absorb summer irrigation and rainfall with less runoff or puddling. Root growth is also improved.
Fall Aeration helps existing grass improve root systems and nutrient uptake, and benefits any seeding done in fall. The healthier root system and nutrient uptake helps winter survival and appearance.
For cool season grasses, both Fall Aeration and Spring Aeration help break up compacted soil, enable better oxygen and water penetration to the roots, and help to develop a rich topsoil. Your grass will have greater nutrient uptake giving you better and deeper root growth.
Fall seeding is required to maintain dense, healthy strands of grass in cool-season lawns. The average life cycle of fescue is about 3 years and every year, the normal fescue lawn loses about 1/3 of its grass to age; it only makes sense to replace what’s lost.
