What is lawn aeration?
Lawn aeration is the process in which you increase your lawns overall ability to breathe, absorb more nutrients and allow water to penetrate deep into the soil bed. Aerating is a vital process of keeping a healthy, lush lawn throughout the growing season. It’s also described as a procedure in which holes are inserted into the garden surface to increase airflow between grassroots. Aerating your lawn also assists in the breakup of layers of thatch that can build up over time within your grass blades.
Why should you aerate your lawn?
Soil compaction kills lawns. It turns them into a mossy, dusty, weedy mess. Therefore, to avoid any horrendous issues, regular aeration needs to take place. The more compaction that the surface undergoes, the more often you should aerate your lawn. Good drainage conditions and adequate topsoil air intake also aid in producing healthy lawns. Air and water are required for microorganisms, which help break down layers of thatch within your lawn. By aerating your lawn, you are encouraging the growth of healthy, deep-rooted grass.
When should you aerate your lawn?
As previously mentioned, you need to aerate your lawn based on its usage and the amount of stress of compaction your soil is under. Another factor to consider is the soil type that your lawn sits on. Below is a table describing how frequently you should aerate your lawn:
|Annually/ Rainfall Dependant
Choosing the best time during the year to aerate your lawn can be difficult depending on your circumstances and the amount of compaction and thatch build-up that you encounter. The best way to see if your lawn requires aeration is to insert a screwdriver (any type) into the surface of the lawn. You should not have to apply much force for it to pierce the surface. If you have to apply lots of pressure because the ground is too hard, then your surface requires urgent help.
In most situations, all lawns should be aerated annually, with the most popular time being Autumn to do so. This is because outside temperatures are still warm, encouraging new growth, however, just at a slower rate compared to springtime. Aerating your lawn in Autumn will prepare it for the long winter ahead. In addition, this will ensure that your grass is in the best possible condition to grow in the following year. Besides annual treatment, there are some very common observations to look out for just in case your lawn requires aerating more than once a year.
A Thick Thatch Layer
Lawn thatch is a build-up of dead grass blades, moss and other organic matter in between the grass pile. Without regular treatment of removing thatch from your grass, it can cause devastating issues with your lawn. Effectively, the thatch stops any absorption of water and sunlight from getting to the roots of the grass blades. In short… smothering your lawn to death.
If your lawn is far too compact, then it is far more susceptible to disease. Most lawn diseases are fungal and can be treated with regular maintenance and care. By aerating your lawn, you can allow the soil bed to breathe and circulate properly, which in time, will help prevent and manage any lawn disease. Lawn diseases can be noticed by a change in your lawn’s pile or by discolouration.
Compacted lawns eventually turn dry and brittle. This can eventually lead to a very patchy, uneven lawn overall. Therefore, if you notice that your lawn is turning a pale/straw-like colour, there is a problem.
Poor Moisture Holding
Lawns that have poor moisture holding, dry much quicker and do not absorb as much water. This can be affected by which type of soil your lawn is laid on. Although often this can be because of the levels of compaction. Keep a keen eye open, especially when it has just rained for any runoff that may occur.
What tools can you use to aerate your lawn?
There are several designs of aerators that are available on the market, all of which are straightforward to use. However, depending on the size of your lawn could determine which method you decide to choose.
