If you struggle to maintain a healthy lawn at home, the Greenworks Dethatcher (27022) will never let you down. While this might sound odd to some people, the key to having a lush and healthy lawn at home is a dethatching – whether you agree or not.

Dethatching is a year-round activity but is best to do during the fall and spring, depending on your home’s grass species. Which are the signs that you need to detach your lawn? Well, keep reading as we have covered this topic in detail herein.

Should you dethatch your law – This is the question –

Before we review the GreenWorks Dethatcher (27022), let us learn a thing or two about ‘thatch.’

What is Thatch?

Thatch refers to a thick layer between the grass and the soil, typically composed of organic materials such as rhizomes, leaves, stolons, dead stems, dead grass, and roots. Even though most people think that thatch is good due to its organic composition, this is not always the case.

By creating a waterproof barrier between your soil and grass, thatch disrupts the natural flow of water, nutrient, and air, lowering moisture levels and its fertility over time. Primarily, contrary to the common belief, that will slowly choke the life out of your lawn, impeding growth.

Excessive thatch also encourages moss’ growth, provides a suitable habitat for insects, and harbor disease-causing organisms that will decimate your lawn. Moreover, from a biological perspective, thatch is dead and therefore does not add to lawns’ nutritional value in any way. It lacks biological activity, readily absorbs water, and dries faster than natural soils do, starving plants off the water in the summer.

Thatch is not 100% bad. However, if your lawn remains brown after mowing and watering your lawn, y6ou might have an excessive amount of thatch that needs action. Furthermore, if your yard feels ‘spongy’ when you jump or walk on it, you might have an excessive amount as well.

Too much Thatch is bad

Having too much thatch on your lawn is terrible as it will stifle growth and deny you the lush green lawn that you have always wanted. This was the case in my youth as my dad never dethatched out yard – we could have benefited from such a machine back in the eighties, as our lawn’s health was sub-par. Soft, healthy, and vibrant lawns provide a plush lounging spot that you can enjoy with your loved ones, kids, and or friends.

If the thatch on your lawn has grown to over ½-inc thick, you will have to dethatch soon to boost lawn health. To ascertain this, cut a small area of your lawn and use a measuring tape to check the thatch’s depth.

The GreenWorks Dethatcher (27022) – or any other premium model – can boost aeration, natural water flow, and nutrition of your lawn and stimulate natural growth. Thus, if you have a weathered lawn, you will notice a boost in its strength, thickness, and lushes in a few weeks.

You should consider detaching your lawn at least once every year, six weeks before the autumn’s frost and or before the soil heats up in the summer – but dethatching once every two years is also acceptable for lazy homeowners. Dethatching in the fall is the most beneficial because you can kill two birds with one stone. Apart from improving your lawn’s health, it can also slow the growth of weeds the following year.

Regular dethatching stimulates the growth of new buds from the base of grasses, preventing dead grass from accumulating at the grass base. As such, for a few minutes of work, you get new grass shoots free.

For the best results, never dethatch your lawn during a heatwave or a drought. Learn more about thatch.

Aerification

Aerification is one of the best strategies for maintaining a healthy lawn, as it prevents the growth of thatch. Here is a quote from the Garden department at the University of Minnesota:

Compacted soils, primarily with poor drainage, are more susceptible to growing thatch than loose and well-draining soils. If you have such soil, consider aeration, as it can boost air penetration and moisture retention in compacted soils. Moreover, it can help the grasses on your lawn develop healthier and deeper root systems and stimulate microbes to break down thatch into a nutritious mash. For the best results, use an aerator with hollow times or spoons, as they lift the core of soil to the surface better than other comparable models.

Check out these aerators as they always get the job done:

The GreenWorks Dethatcher is a robust yet simple to use power tool, engineered to remove thatch from lawns by lifting it to the surface, after which you can rake it and burn or dispose of it in your preferred way. The machine has multiple spinning tines that rotate vertically to pull thatch from that top layer of the soil.

This electricity-powered device uses a 10-ampere electric cord that you must manage while it is in use. For most people, this is a simple process, which they do not mind doing. The tool is also easy to maneuver on lawns without requiring unique skill and or energy. Thus, if you have never used one before, expect a memorable experience. Its use is as easy as vacuuming a carpet is.

To cover a larger area and get more work done faster, you will need a Southwire 25890002 2589SW0002 Outdoor Cord, a 12-gauge heavy-duty wire that can supply electricity GreenWorks Dethatcher. The power cable is 100 feet long, which is enough for most people and is available online or locally in many countries. Where you will order one is up to you but make sure you get an original product.

From the description of this dethatcher, the product has tines with an adjustable depth (three), which is accurate but somewhat misleading at the same time. Even though the tines have three adjustable levels, one depth level is for transporting the tool and not for dethatching lawns. As such, you get two working depths – 3mm and 10mm.

If this is your first time interacting with GreenWorks, its quality should never be a concern, as the company has a reputation for making top-grade garden and lawn tools. Moreover, you are getting an affordable Dethatcher that produces reliable power and is easy to handle on lawns.

With each original model you purchase, GreenWorks offers you a four-year limited warranty. None of its competitors offers a similar guarantee. Personally, while ordering such an electrical product, I pay keen attention to the warranty while making my decision. This way, you are confident that that company will have your back whenever something goes wrong with the product or when it needs a quick fix. You also get a set of replacement tines from the manufacturer free.

Here is an awesome video of the dethatcher in action:

Before you detach your lawn, make sure that the grass is around 2-inches higher to allow the tool to dig deeper into the ground.

Moreover, you will have to buy a dethatch bag separately as this tool does not come with one. This is heartbreaking to some people, but it might be why the company manages to sell the Dethatcher cheap. If this is essential to you, you will have a better experience with the Sun Joe AJ801E, which we have discussed later on.

Before I conclude this review, I would like to reiterate that GreenWorks ranks among the best dethatchers for people with large lawns. If you have a contrary opinion, I implore you to identify a better model that delivers professional results and can withstand the test of time. From the uncoerced customer reviews shared online, it is evident that the product has satisfied the needs of thousands of people globally. It is also apparent that its reputation is top-notch, making it the ideal choice for your home.

Thus, if you need a heavy-duty product that excels at dethatching big lawns, this is one of the best products for you. If you need something that can handle more demanding jobs, you should check out the Agri-Fab 45-0343 Tine Dethatcher, which we have reviewed in detail herein.
