The Benefits of Lawn Aeration

Maintaining a lawn so it is the beautiful lush green and healthy lawn you dream of can take time and effort. Mowing, feeding, weeding, pest control etc., are all part of a great lawn care programme, however what is often ignored is the importance of the lawn’s root zone. It’s in the root zone that the serious work takes place. It’s here where your lawn’s grass roots will extract the moisture and nutrients from the soil so the process of photosynthesis can take place and the grass plant can then produce the food it requires, by using the energy from the sun.

the benefits of lawn aerationLawn Aeration is a process that involves perforating the soil with small holes. This process will allow air, nutrients and water to penetrate the grass roots, helping the roots to grow deep and strong, resulting in a vigorous healthy lawn. By pulling the small plugs (approx ½ inch) of soil and thatch from the ground it will promote a deeper and healthier root system.

There are two types of Aeration to consider:


1. Hollow Tine Aeration is accomplished by the use of a mechanical lawn aerator equipped with hollow cylinder tines that are designed to penetrate and shatter the soil. This type of Aeration is the most effective on severe compacted lawns. As Hollow Tine Aeration removes the cores of soil from your lawn it is very important to remove these cores, as they are not only messy and unsightly but they will harbour weeds and moss spores as well as adding to your thatch build up issue.

2. Solid Tine Aeration is an operation that green keepers on golf courses and athletic fields perform at least once a year. Your lawn can benefit from this too! It involves driving solid metal spikes into the surface of your lawn, they can be punched in quite deep, say up to seven inches or more. This is the simplest and easiest way to relieve minor compaction issues to refresh your lawn. When a Core Aeration on your lawn is carried out annually it will go a long way in helping it grow deeper roots and uptake moisture and nutrients much better. As Solid-Tine aeration does not remove any soil, so the holes will eventually squeeze back together after a few days. At Lawnscience we would recommend this type of Aeration to be part of a general maintenance treatment that can be used on well established lawns.

The main reason for Aeration is to alleviate soil compaction. If your soil is compacted, it can ruin your lawn. There are billions of bacteria living in your grass root zone which play a vital role in the health of your lawn. In order to do this they will need a good supply of oxygen. Soil naturally contains oxygen but if it will be greatly reduced if your soil is compacted with a heavy layer of thatch and has poor drainage. Grass plants will suffocate as the compaction will prevent the much needed air, water and nutrients from reaching the root zone.
Aeration will allow oxygen to circulate and refresh the beneficial bacteria by creating small channels in the root zone. The healthier the root zone, the healthier the lawn!
