This lowers compaction in the soil, and the holes can stay open for a long period of time, enabling water, fertilizers, and air to reach the roots. Meanwhile, a plug/core aerator takes out the soil from the ground and leaves the core in the yard. Because there’s no soil taken out from the ground, watering will make the compacted soil around holes to enlarge and close. Spike aerators create holes in the ground by pushing the soil sideways as wedge-shaped spikes penetrate the lawn. And the best part is that the effects are long-term, unlike those of spike aeration models.įact: Some of the best core aerators out there are mechanical. A plug aerator is much more effective at eliminating soil compaction, even in lawns with clay soil. Plug aerators are incorporated with hollow tines that take out around an inch of thatch from the core when pushed into the soil, making it well-aerated. This makes a core aerator very effective equipment for relieving soil compaction on a long-term basis. Core/Plug AeratorĪ plug aerator or coring aerator is quite different from a spike aerator because it removes plugs of thatch from the soil. It will take you a lot of time and energy just to finish the job. Just imagine spike aerating a thousand square foot lawn using spike lawn aeration shoes. On the other hand, spiked lawn aerator shoes are significantly slow at doing the task. Some mechanical spike units are curved and can give extra deep penetration, sometimes up to nine inches deep, without making any mess of plugs on your lawn. The tiny holes don’t lower core compaction, but instead, they increase compaction deep in the ground. Eventually, the ground will readjust and close the small holes you made with the spike aerator. Rather than taking out soil plugs from the core of your yard, the spike aerator’s sharp tines push the soil down and to the sides. Spike lawn aeration is good, but it eliminates soil compaction on a short-term basis only. It only pokes holes in the ground to eliminate the compaction. Compared to a coring aerator, a spike aerator doesn’t take out any soil from the lawn. This type uses wedge-shaped solid spikes to punch holes in the soil to make it loose. There are two types of walk-behind aerators: Spike Aerators What Are the Types of Walk Behind Aerators? The gaps and holes made allow essential nutrients, water, and air into the grass roots. The cores come out from the other end of the plugs and fall on the lawn. As you push the tool, it will engage the hollow tines, which dig deep into the ground and take out plugs. Because it comes at a reasonable price point, it does make the best pick for homeowners on a restricted budget.Ī walk behind core aerator operates by means of pushing. But it works better compared to handheld aerators and lawn aerator shoes. In particular, a walk behind core aerator may not be as effective as stand-on units. In compacted soil, aeration enhances soil drainage and encourages microflora, microfauna, and worms that need oxygen.
