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:
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 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 water, oxygen and other nutrients access to the root zone.
Fracture-tine aeration is a mechanical process that involves cutting tiny slits into the lawn. With the twist of the blade, the tines acts 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.
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.
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.
Aeration forms an important part of a good annual programme of lawn maintenance. It is included in the Enhanced and Complete Programmes.
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.
