Aeration and Seeding

Aeration

The benefits of core aeration are many, including a stronger and deeper root zone, better drainage, decreased thatch, and better water and nutrient uptake. With every rain, mow or foot step, the soil is compacted tighter and tighter, making it tougher for the roots to squeeze through the spaces. This soil compaction results in shallow, thin roots that are simply being strangled, as they need pore space for air, water and food nutrients to survive. 


Core aeration removes plugs of turf to reduce compaction, increase airflow, puncture the thatch layer, and increase water and nutrient penetration. As the turf cores break down over the next couple of weeks, the micro-organisms actually attack and reduce the existing thatch layer. 


Seeding

Following up core aeration with seeding is a great way to thicken up a thin lawn or add a hardier, more drought or disease-resistant grass variety to your property. Good seed-to-soil contact is essential for seeding success, and the new grass seed will have an easier time growing in the holes left behind by aeration. Keep in mind that if your lawn has been seeded, the soil should be kept moist with light, frequent sprinklings until the new grass is well established. 


*That time commitment should be considered if your lawn does not have an automatic irrigation system.

It is best to aerate through September and early October
