What is Aeration?

Aeration is the most effective way of reducing sub-surface thatch and compaction in lawns, often the main causes of moss.

The benefits of Aeration are:

  • Thins out below-the-surface thatch
  • Relieves compaction in the soil
  • Reduces/removes the moss loving environment
  • Increases water, nutrient and air access to the soil
  • Encourages root development
  • Improves the lawn’s ability to cope with drought and disease
  • An overall healthier lawn

Aeration is an essential part of a good annual lawn treatment programme and is included in our NutraGreen Standard and Ultimate Programmes.

Although there are a few different types of Aeration, hollow-tine and fracture-tine are the best for lawns. We will recommend the one most suited to the condition of your lawn.



Hollow-tine Aeration

Hollow-tine Aeration is an effective way to thin-out sub-surface thatch in a lawn. It does this by mechanically removing thousands of cores from the lawn allowing essential water, air, and nutrients access to the root zone.


Fracture-tine Aeration


Fracture-tine Aeration is a mechanical process that involves cutting tiny slits into the lawn. With the twist of the blade, the tines act as a small spade, fracturing the soil and adding air. No soil is removed during this process so no cores are left on the lawn.


How does GreenThumb know if my lawn needs aerating?

We check the lawn by taking a number of cores samples in a variety of places over the lawn. The process of taking a core sample allows us to take a closer look at the levels of sub-surface thatch and what the soil is like. We will be able to tell how compacted the soil is by examining the conditions of the roots and how tight knit the soil is. This evidence provides us with enough information to recommend Aeration for compaction. Likewise the thickness of sub-surface thatch tells us if Aeration is needed.

What time of the year should a lawn be aerated?

We carry out Aeration between the latter part of the year and spring. We choose this period as it usually gives the greatest opportunity for the root zone to receive water and air. Even very cold conditions following Aeration are most helpful in the break-up of compact soils or sub-surface thatch.

How often should a lawn have Aeration?

Aeration forms an important part of a good annual programme of lawn maintenance. It is included in the Standard and Ultimate Programmes.

What do you do to collect the cores left over from Aeration?

Although some experts suggest that going over the lawn with a rotary mower without the collector turns the cores into a form of dressing, this is only applicable to certain soil types. Your local GreenThumb might also offer a service to collect them. Ideally, for a lawn, aeration should be immediately followed by scarification. Scarification removes thatch, which is then collected and bagged for disposal.
