It's easy to overlook lawn aeration as one of the most important lawn maintenance techniques. You can use this technique to keep your yard healthy and green while encouraging growth. Lawn aerators come in two primary types: plugs and spikes.  

 

A plug aerator, also known as a core aerator, removes plugs of soil from your lawn, while a spike aerator has rollers with spikes, puncturing the ground.

The root system of your lawn is nourished, hydrated, and oxygenated by aerating your lawn. With a healthy, deep root system, your lawn will be able to resist invasions from unwanted weeds and grasses.
