Why Core Aeration Matters for Your Lawn
At Master Gardener Lawn Care, we recommend annual core aeration as one of the most effective ways to promote a deeper root system, improve water and nutrient absorption, and break down thatch. If your lawn suffers from compacted clay soil or excessive thatch buildup — both common problems in Macomb County — aeration is a must.
What Is Core Aeration?
Core aeration is the process of mechanically removing small plugs of soil and thatch from your lawn. These plugs are left on the surface, where they break down naturally and return nutrients to the soil. The holes left behind allow more air, water, and fertilizer to reach the root zone — creating the ideal environment for healthier, thicker turf.
What Are the Benefits of Core Aeration?
- Relieves soil compaction, especially in heavy clay soils common in Michigan
- Reduces thatch buildup, which can block water and nutrients
- Improves oxygen and moisture flow to the root zone
- Enhances fertilizer effectiveness by allowing nutrients to reach the roots
- Encourages root expansion, resulting in a thicker, more drought-resistant lawn
When Should You Aerate?
In Michigan’s northern turfgrass zone, the best times to core aerate are early spring and early fall. These seasons offer the right combination of soil moisture and grass growth to maximize recovery and benefits.
Pair Aeration with Overseeding
After aerating, your lawn is primed for success, making it the perfect time to overseed. Grass seed naturally falls into the aeration holes, where it’s protected from wind and birds. With proper watering, this seed germinates quickly, helping to fill in bare or thin areas and improve turf density and appearance.
Why Golf Courses Do It — And You Should Too
Golf course superintendents know that aeration is key to turf health, which is why they do it at least once a year. Home lawns benefit just as much. If your goal is a lush, green lawn that turns heads, annual core aeration is one of the smartest investments you can make.
