One way you can aerate your lawn is by way of liquid aeration. Liquid aeration is the process of opening up channels and passageways for nutrients and resources to reach the roots of your grass. How it works is a liquid solution is sprayed onto your turf and eventually sinks into the ground. As the product is absorbed into your lawn, it will break down the dense matter to loosen up your soil.
Core aeration provides the same results as liquid aeration, but the process is very different. Instead of spraying a liquid solution on your lawn, a machine called an aerator travels across your property to loosen up your soil. The aerator plucks tiny cores from your yard, leaving behind plenty of holes. These holes function as passageways for nutrients and resources to find their way to the roots of your grass.
Leave the cores on your lawn after the aeration process. The cores will break down and recycle nutrients back into your soil.
