Keep your lawn thriving with these aeration tips and tools
If you have a garden, you tend to it because it is a living thing. Your lawn is also a living thing. To thrive, it needs nutrients, water and air.
A plant gets all of these essentials from the soil. If the soil is compacted, these elements will not get to the roots in the levels needed and your lawn will begin to die. Aeration can change all that. It is the miracle chore that can make an unhealthy lawn thrive just by doing it once.
What is lawn aeration, and why is it important?
When you eat, you use your mouth. The same thing goes with drinking water. When you breathe, you use both your nose and your mouth. Imagine how tough it would be to survive if your mouth and nose were blocked.
A plant eats, drinks and breathes primarily through its root system, which is underground. When the soil gets compacted, nutrients, water and air have a hard time getting to the plant’s roots. This means a plant cannot get the nourishment it needs to survive.
When you aerate your lawn, you are actually breaking up the soil. This allows life-sustaining nourishment through so your grass can thrive.
How do I know if I need to aerate my lawn?
Many guides tell you to look for grass that is thinning, losing its color or diseased to identify an aeration problem. However, that does not give you the whole picture. Since aeration is a problem with the soil, it can be hard to judge if you need to aerate by just looking at your lawn. To know for sure that compacted soil is the problem, you need to pay attention to other clues.
- Is your soil hard? Hard soil is compacted soil. If your soil is hard (and there hasn’t been a drought), it is a clear indication your lawn would benefit from aerating.
- Do you have puddles? Puddles on your lawn are a good indication you need to aerate, but they could also indicate other issues. If there are puddles in your lawn long after it rains, it either means the soil is saturated, there’s a low spot or it is so compacted that it can’t absorb the water like it is supposed to.
- Does your soil dry out fast? This might seem to contradict the puddle sign, but it is the same symptom. If water does not get absorbed by your soil, it will evaporate. Instead of having moist soil after some light rain, you will have dry, hard soil. This is another clear indication that you need to aerate.
How often do I need to aerate my lawn?
If you aerate your lawn, it’s a good thing. The problem is, once people realize the benefit of aerating their lawn, they can do it too often. Since aerating your lawn adds stress to the plants, it is best to aerate your lawn only when it needs it. At the most, this could mean once each year. In general, though, it might mean once every few years. The way to know how often your lawn needs to be aerated is to watch for the clues listed in the previous section.
When should I aerate my lawn?
The best time to aerate your lawn is during its peak growing season. If you have cool-season grass, this would be early spring or fall when the temperatures are not too warm. For warm-season grasses, this would be in the early summer when temperatures start to warm up but before they are hot. It’s easy to tell when the peak growing season is because that is when your grass is growing the quickest.
