Lawn care experts recommend that you aerate your lawn at least once a year. However, if your lawn received heavy foot traffic regularly or if the turf lies on heavy clay or sub-soils, aeration may be done more than once annually.
Lawn aeration offers several benefits. These include the following:
• It encourages new root growth. When a lawn is aerated, new space between the soil particles actively encourages the roots of the grass to grow. When a root system is better, the grass plant will grow better and healthier as well.
• It provides relief to soil compaction. A lawn that is regularly used and mowed causes the soil particles under the surface of the grass to get slowly squashed together to form an impenetrable layer. This process soon forms a hard layer on the turf which makes it difficult for the grass plants to grow properly. Through aeration, grass plant roots can grow and regenerate better not in the soil itself but in the spaces between the particles of the soil.
• It reduces the build-up of thatch below the surface. Through aeration, the microbes in the soil are stimulated and this helps reduce thatch. Lawn care experts say that the process of hollow tinning can also remove a core of soil and as such, can make holes in the thatch layer and help to break it up more effectively. Consider carrying out this process as well when aerating your lawn to reduce thatch more effectively.
• It boosts the infiltration rate of water into the soil. This lawn care process helps minimize surface water since it increases percolation of rainwater deeper into the soil.
• It improves surface drainage. Through aeration, you can prevent the lawn from getting so muddy due to heavy or regular rainfall since this process helps take water away from the surface of the lawn.
• It effectively stimulates increased nutrient uptake. When the grass nutrient uptake is improved, the plant can get the best out of any further treatments, particularly fertilization.
• It helps facilitate better gaseous exchange between the soil and atmosphere. Lastly, aeration increases the activity of microbes which, in turn, improves the grass plants performance and helps get oxygen down into the root zone of the grass.
