Best Lawn Aerator | UK Guide | 2023
If you want to keep your garden looking lush and healthy, you should definitely think about purchasing a lawn aerator. Your lawn and its underlying soils compact over time thanks to things like rain and footfall. This compaction eventually prevents air from penetrating into the ground, throttling grass roots and causing your lawn to wither.
A decent aerator will help loosen the soil, allowing air, water and nutrients to once again penetrate deep enough that they can feed roots and ensure your lawn thrives. Is your outdoor space in desperate need of some care and attention. Our guide explores all the things to remember when selecting the best lawn aerator.
Types of Lawn Aerator
When selecting a lawn aerator, you have two main models to choose from. The best choice is without doubt an electric aerator. This push aerators make use of powerful electric motors and roller spikes that take much of the hard work out of aerating your line. As you push these appliances across your lawn, the spiked rollers dig deep into the soil, allowing air and water to filter down to grass root level.
These types of aerators usually provide you with multiple cutting heights and allow you to make use of other features. They also tend to be fairly wide, while grass collector bags mean you can operate multiple functions at once and house any trimmings to save you having to rake the lawn afterwards.
A manual aerator is also something to think about. These are made up of a roller drum and a handle component. As with an electric push along aerator, you have to put some manual effort into getting these aerators across your lawn. These manual aerators are usually made from heavy materials, such as iron or steel, to compensate for the lack of a motor and a dense covering of blades. You can also tailor the roller weight with materials such as sand. If you only have a small lawn, a manual aerator is a good option. They are also much more affordable.
Other aerator products are also available. Aerator shoes are a popular option for those who want to supplement a conventional aerator. These shoes feature an array of spikes on the underside of the sole, with each step you take delivering deep channels into the soil. However, these shoes are no real substitute for a conventional aerator.
Cutting Blades & Blade Width
The blade width of your aerator will speed up how quickly you can aerate your lawn. A roller width of around 30cm should be more than sufficient for most lawns, although you will find a good range of aerators on the market that offer a width of 40cm or more. If you have a small garden with tight spots and corners, a narrower roller might be the best choice for you.
Blade material is also something to consider. If your lawn soil is particularly dense or gravelly, a robust blade material will help penetrate into the soil more easily. If you have never aerated your lawn before and the soil is particularly impacted, you almost certainly want to purchase an aerator with very strong blades.
There is no point purchasing an aerator if it can not penetrate deep enough into the soil to provide your lawn with the nutrients it needs to thrive. The majority of lawn aerators will provide you with adjustable cutting depths that can be changed with a switch or nozzle. An adjustable penetration depth is particularly handy if you want to first loosen very compacted soil, but then want to aerate your broken in lawn with less aggressive penetration. Bear in mind, you will only find adjustable penetration depth settings with electric or motorised aerators.

The Bottom Line
If you are looking for an electric aerator to take care of lawn maintenance, make sure are purchasing a model that will be able to the size of your garden effectively. Cutting widths are something you should definitely focusing on, especially if you have a larger lawn. You will also want to ensure any collector bag has a large enough capacity to house a substantial amount of cuttings and garden debris, without you having to forever empty and reattach it.
Adjustable cutting heights are also desirable, especially if you want to use your aerator for a range of grass heights and varieties. As with any electrical appliance, the more proficient the motor, the more effective your aerator will be at handling the task in hand.
Should you wish to keep things basic with a manual roller, make sure it is large enough to handle large sections of lawn without you having to put in too much manual effort. Any manual roller should be made of a high-grade material that will hold up well against outdoor conditions and the elements, so look for steel or iron rollers. These manual aerators should also allow you to tailor the weight by adding and removing sand or a similar material.
