Lawn aeration is an important part of lawn care, and while the regularity will vary according to a number of factors, the main reason is the soil type.
A heavily clay-dominant soil will be more prone to compaction and will therefore require a more intensive and regular aeration programme compared with a lawn that is free-draining and on sand-based soil. By definition, we aerate to keep soil healthy, to maintain the balance of air and moisture available to the roots of the grass plant.
Why is lawn aeration needed?
Well-aerated soil will absorb rainfall and irrigation more effectively, and drain more freely, allowing organic matter to be broken down in allowing the recycling of vital nutrients.
Additionally, it is important that the grass plant forms an extensive root system for healthy growth and to maximise their tolerance to stress by ensuring that they have access to water and nutrients.
In a poorly aerated soil pore size will be reduced and result in a loss of soil structure from increased compaction. As a consequence, there is less root development and a reduction in water and nutrient uptake by the plant.
Better rooting in well-aerated soil will also help the grass plant survive during periods of hot and dry conditions, as the deeper the roots the more chance they will find the remaining moisture available.

Are there different types of lawn aeration?
There are two main types of aeration, solid tine and hollow tine.
Solid tines are generally the tine of choice during the spring and summer, which comes in a range of diameters and lengths but will produce a round hole in the lawn allowing for oxygen and moisture to enter the soil profile.
Routine aeration should be concentrated within the top 100mm of the lawn, and while the selection of equipment can depend on the size of the lawn area, it is generally completed using a self-propelled mechanical machine.
For localised work in confined spaces and around the edge of the lawn, hand tools, such as the trusty garden fork still serve an important function, as regular aeration is the key to a strong and healthy lawn, and in summary, relieves soil compaction, improves drainage and soil structure, encourages strong roots, reduces organic matter in the upper soil profile, and increases drought tolerance.
