How To Aerate Your Lawn

Aeration is one of the most vital maintenance operations to be carried out on any turf area.


Aeration is a process that creates lots of holes in your lawn. It is carried out to help lawns by ventilating the soil, improving drainage and encouraging better root development. The machine does not just spike the ground, it also heaves and agitates the soil, fracturing its structure and facilitating the air/nutrient/moisture distribution. This process is a key factor in keeping lawns green and healthy.On a golf green, for example, greenkeepers will do this many times a year to keep the turf in great shape.


Why do lawns need Aeration?


The purpose behind all aeration techniques is to maintain or increase the proportion of pore space within the soil structure. Compaction of the root zone leads to water logging, a build up of unwanted thatch and a decline in the appearance of the lawn.

An open, healthy soil structure will warm more quickly in the spring promoting good root extension. This will enhance the grass plants ability to use the nutrients applied throughout the year, and also become more drought tolerant.


When is the best time to Aerate?


You can aerate a lawn at any time of the year as long as the ground is not too soft that the machine sinks into the soil and not too hard that the tines cannot penetrate. We carry out the majority of our aerations in the autumn, winter and spring months.

We recommend having your lawn aerated at least once a year for best results. If you are looking to promote a very healthy lawn, you may consider having two or more a year.


How do you carry out Aeration?


It is best to use professional aerators which creates lots of holes in your lawn, piercing the soil profile. These can be purchased or hired. At Will’s Norfolk Lawns we offer three aeration services. These being hollow-tine aeration, solid-tine aeration/spiking and fracture-tine aeration. The type of aeration that is best suited for your lawn will depend on the lawns and soils current condition. Smaller areas where you cannot access with a professional machine can be aerated with a garden fork.


General Benefits of Aeration:


  • Allows oxygen, air and water to penetrate root zone.
  • Improves surface drainage.
  • Reduces moss encroachment.
  • Increases microbial activity.
  • Stimulates root growth and improves nutrient uptake.
  • Increased stress tolerance.
