Will Aerating a Lawn Improve Drainage?

Drainage issues can pose a serious threat not only to the physical condition of your lawn, but also to the structural integrity of your home. As such, it is important to give some thought to how you can ensure that the grass on your property has a good drainage system.

Lawns can suffer from underlying soil compaction, caused by poor soil or heavy foot traffic, or have impenetrable grass, and significant thatch buildup. These types of conditions make it more likely for you to have poor drainage and unhealthy grass. The good news is that aeration can cure these problems before they cause any serious damage.

One of the most effective methods to assist with the drainage of a lawn is to aerate it. It entails making holes or perforations in the turf so that water, oxygen, and nutrients may travel more freely to the grass roots. If your lawn has barren spots, is often becoming blocked with water, or has unhealthy grass that is yellowish in color, you should seriously consider aerating it.

  • Compacted soil: If your lawn feels spongy or bouncy when you walk on it, aeration can help to loosen up the soil and improve drainage.
  • Poor drainage: If your lawn is constantly wet or soggy, aeration can help to improve drainage by creating more space for water to drain.
  • Yellowing or dying grass: If you notice patches of yellow or brown grass, aeration can help to improve the health of your lawn by allowing oxygen and nutrients to reach the roots.

How does aeration help with drainage?

Aeration helps improve drainage by creating more space for water to drain. When the soil is compacted, water has nowhere to go but to pool on the surface. By breaking up the compacted soil, aeration allows water to seep down into the ground, where it can be used by the roots.

Aeration also helps to improve the health of your lawn by breaking up thatch. Thatch is a layer of dead and living grass, as well as other organic matter, that can build up on your lawn over time. If thatch gets too thick, it can prevent water and nutrients from reaching the roots of your grass. By aerating you can help to break up thatch and allow water and nutrients to travel to the roots of your grass promoting stronger root growth.

  • Plug aerators: these remove small cores of soil as they are pushed through the lawn, which helps to aerate the lawn while also topdressing it
  • Rolling aerators: these are rolled across the lawn, and have either spikes or paddles that help to loosen the soil

Liquid Aeration

Unlike conventional aeration, which includes removing plugs or poking holes in the soil of a lawn, liquid aeration merely entails spreading a supplemented chemical solution to the grass. Ammonium lauryl sulfate, the active component, is widely found in soap is commonly used.
