Since the winter months, my lawn had been completely taken over by moss and weeds, with virtually no healthy grass remaining. Having come across gardening guru Monty Don's tips on reviving lawns through scarification and aeration, I decided to try it for myself.
What Is Scarification and Aeration?
Scarifying is a technique that strips away excess thatch and moss from the base of the grass to encourage healthier growth. This is followed by aeration, which involves piercing the soil to improve the circulation of air and water down to the roots.
While Monty Don suggested that a garden rake and fork can be used to scarify and aerate, my lawn is on the larger side, meaning it would require considerable effort and time to complete the task. Instead, I opted to put an electric scarifier that doubles as an aerator to the test. The product in question is the two-in-one VonHaus Scarifier and Aerator 2000W. Using this handy garden tool, I managed to clear moss from my lawn and prepare it for overseeding in just under three hours.
The Electric Scarifier Experience
Priced at £179.99, the VonHaus Scarifier and Aerator 2000W is built to lift moss, clear thatch, and eliminate the build-up that regular mowing simply cannot reach. Scarifying a lawn puts any machine through its paces, so it needs to be robust, well-constructed and capable of taking the strain off the user.
The standout feature of this gardening tool is that it makes scarifying and aerating considerably easier than relying on a garden rake and fork, particularly given how badly moss-ridden my lawn had become. I found this model delivered impressive power throughout, effortlessly stripping away heavily thatched, mossy patches and dead grass from a lawn that had gone untreated for quite some time.
For those who'd prefer a less powerful and more budget-friendly option, the 1800W version of the VonHaus 2-in-1 Lawn Scarifier is also available.
Assembly and Setup
VonHaus claims the product requires minimal assembly, and having put it together myself, I'd wholeheartedly agree. The whole process took no longer than five minutes. The scarifier arrives with two interchangeable rollers: one fitted with metal tines for scarifying and another with blades for aerating. Both feel solid and dependable. It also includes a collection bag with a capacity of up to 55 litres. That said, it fills up quickly — in my experience, it stops collecting at around 40 litres before needing to be emptied.
Using the Scarifier
With the scarifying roller fitted, it was time to put the tool through its paces. At this stage, I encountered a minor snag — the power cable was rather short, though an extension lead sorted the problem instantly. As I'd never scarified my lawn before, nor operated a scarifying machine, I decided that caution was advisable. So, I ran my scarifier on the highest setting. However, this proved ineffective. It barely lifted any moss at all, so I gradually lowered the scarifying blades to assess the impact of each level.
Eventually, I took the plunge and opted for the lowest setting — with a lawn in such poor condition, fairly drastic measures were clearly necessary. It's worth noting that future scarification come autumn won't require the blades set quite so low, as the main moss problem will have already been tackled. But on this occasion, it was something of an emergency.
Scarifying is a rather nerve-wracking experience as you guide the machine across your lawn and witness a trail of devastation left behind. I was genuinely taken aback to find the collector box completely full by the time I'd reached the end of the very first pass. The lawn was riddled with ridges at this stage, caused by the scarifier blades, yet even after this initial run, substantial amounts of moss remained lurking beneath the surface. So I ran the scarifier back and forth across the entire lawn, from one end to the other. Then I worked diagonally from the bottom left to the top right, followed by a final diagonal pass from the bottom right to the top left.
Aeration and Final Thoughts
With scarifying complete, it was time to aerate. A swift swap of the rollers and the machine was ready. It operated in much the same fashion as the scarifier, only with greater intensity. While I wasn't the biggest fan of how it aerates the lawn, I have nothing but praise for its scarifying function. Its design features and depth settings make it adaptable enough to suit a wide range of lawn types, and it's straightforward enough to be operated by those with little to no scarifying experience.
There are, of course, other two-in-one scarifiers and aerators available on the market. The Hyundai Electric Lawn Scarifier Aerator Lawn Rake 1800W can be snapped up for the more affordable price of £129.99. For those seeking a more budget-conscious option, albeit considerably less powerful, the Hawksmoor 1200W Electric Lawnmower is on sale for £49.98 from ToolStation.
Having completed the aeration, the next stage in restoring the lawn will be to overseed before applying a layer of top dressing. My advice is to keep your nerve, as your lawn will likely look alarmingly bare after scarifying and aerating.
