Compacted soil (the problem) & aeration (the solution)
As we at Dickson Leaf & Lawn Care — or any other knowledgeable landscape specialist, for that matter — will tell you, soil compacting is a threat to your having a healthy, beautiful Dickson lawn. Soil compaction is exactly what it sounds like: As the weeks and months go by, the soil in your lawn is pressed down by foot and vehicle traffic, resulting in compacted soil. Regular lawn mowing is even a culprit; prolonged wet conditions caused by poor drainage can also contribute to soil compacting.
Why compacted soil is bad for your lawn
Soil compacting over time becomes a detriment to good lawn health because compacted soil has much less air in it. Plants absolutely depend on air in the soil; air in the porous soil supplies roots with vital oxygen. Compacted soil disrupts nutrient uptake and absorption, prevents roots from growing, and does not allow proper water filtration, among other negatives.
How lawn aeration helps
Proper lawn aeration helps combat packed soil by creating holes in the ground, thus allowing air to penetrate the soil and creating more room for compacted soil to loosen, creating more porous soil. Lawn aeration can be compared to puncturing tough meat prior to marinating it; the holes created in the meat allow liquid to seep in. Likewise, the new spaces within the soil of a freshly aerated lawn invite life-giving air — and thus oxygen — back into the soil.
Proper lawn aeration also creates additional room for grass roots to expand, for necessary/ helpful microorganisms to do their chemistry thing, and much more. Rainwater is able to soak more deeply into the soil, and the danger of harmful fertilizer, gray water, or pesticide runoff is greatly decreased.
The best time to overseed your Dickson lawn the first time each year is in early spring just after we have aerated your lawn. We cast quality fescue (or other appropriate) grass seed evenly throughout your lawn and use straw where needed. Within two to four weeks, you can enjoy a thicker, greener lawn.
