After the rain, puddles linger, old clippings collect between the blades, and your favourite corner by the garden path keeps getting thinner? Then it's worth taking a closer look beneath the green surface. Whether your lawn needs aerating depends on where the problem lies: up top between the plants, or deeper in the soil.
The short answer: Surface raking is done with springy tools that comb out loose material. Core aeration uses hollow tools to remove small plugs of soil, creating pores in the root zone. Both jobs have their place in lawn care. What matters is working out which one your lawn actually needs right now.
Lawn raking and scarifying are often lumped together in everyday garden talk, and soil aeration gets thrown into the mix too. In reality, these three methods do quite different jobs. Before you drag a machine out of the shed, this distinction is worth understanding:
Springy tines rake the lawn at surface level: they lift dead grass and loose debris out from between the blades. A lawn rake can help pick up loosened thatch and moss lying near the surface. Unlike scarifying, the turf isn't deliberately cut into with blades. So raking is mainly a gentle tidy-up between the grass blades.
If a dense, matted layer sits on the soil, scarifying may be worthwhile, provided the lawn is strong enough to cope. Vertical blades cut into the top layer and pull out the compacted material. The difference from raking lies in the greater working depth. A healthy lawn without a troublesome layer doesn't need this more intensive treatment as routine maintenance.
Raking and scarifying mainly work the surface. If the soil underneath is compacted, hollow tines used in core aeration can remove soil plugs and loosen the rooted zone. This creates extra channels for air and water. Suitable treatment can bring more oxygen to the roots; however, it won't fix a dense barrier layer that sits well below the working depth.
You can also tell the difference by the result: raking removes plant debris from the surface, while working with hollow tools ejects small soil cores. The Sports Turf Research Institute (STRI) describes this kind of core removal as an effective method against near-surface compaction.
For small punctures in the top layer of soil, you can use a hand-operated lawn aerator. Work on ground that is slightly moist and firm enough to bear weight, and adjust the pressure to suit the conditions.
Targeted surface treatment
The aerating spikes create small punctures in the soil as you push the tool. The handle lets you steer and control the pressure applied. This tool is best suited to smaller areas you want to work by hand.

Good to know: The FX-RL400 uses solid spikes and doesn't remove soil cores. For true core aeration, you'll need a hollow-tine tool. Combing out loose debris with a spring-tine roller is also a different technique altogether.
If you want to fill in bare patches after lawn care, it comes down to evenly spread seed, good soil contact and the right moisture levels. These tools help you with each step.
Even seed distribution
Use the spreader to distribute dry seed or suitable granules evenly across larger areas. Match the application rate to the material, and always test it first with a measured amount over a known area.

Firming in fresh seed
After sowing, use the roller to press seed gently into prepared soil, improving soil contact. Adjust the weight via the filling; only add as much ballast as needed for a gentle press.

Practical tip: Here, the roller is only for lightly firming in seed. Avoid rolling on wet ground, and don't recompact freshly worked areas. The right watering duration depends on soil and weather; the area a sprinkler can cover also depends on water pressure and hose length.
Run your fingers through the grass and check several spots. If loose, dry material lifts out easily, gentle raking may be enough. If moss and thatch form a solid mat, check its thickness and the condition of the grass beneath. The question "scarify or rake?" is answered by this assessment, not by whichever attachment happens to be fitted.
If you suspect compaction, a small spade test at the edge of a problem area is worthwhile. Does the soil feel dense and slab-like? Does water sit there longer than elsewhere? Are lots of roots running shallow, just under the surface? These observations are useful clues, but not proof of a single cause. Shade, unsuitable soil structure or poor drainage can also hold growth back.
For you as a garden owner, that means: look first, then choose the treatment. Water and nutrients reach a healthy root zone more easily when its pores are working properly. Simply poking random holes in the lawn is no substitute for this check.
Work on an established lawn during a mild growth phase, typically in spring or early autumn. Raking is best done when the grass is dry. For deeper soil work, the ground should be evenly moist and easy to work: neither dust-dry nor so wet that it smears on the tool.
Newly laid turf, heat-stressed grass and waterlogged ground should be left alone for now. The same applies to both scarifying and raking: the grass needs to be able to recover afterwards. A free Saturday afternoon alone isn't a good enough reason to work on a lawn that isn't ready for it.
Light raking can be repeated as needed. But you don't have to rake every lawn on a fixed schedule. Whether it needs doing again depends on how much loose material has built up. On heavily used lawns, soil structure may also need repeated attention; how often depends on the ground and the level of use. On a loose, healthy, well-growing lawn, an extra pass brings no automatic benefit.
If you want to cover longer stretches, a cordless combi tool can help. For gentle surface care, simply fit the matching spring-tine attachment.
Combing the surface
With the included spring-tine roller, you can use this combi tool as a lawn rake. For more intensive treatment, swap it for the also-included blade roller.
View product: FUXTEC Cordless Scarifier FX-E2VE38SET
Good to know: This combi tool does not remove soil cores. For deeper soil work, you'll need a separate hollow-tine tool. Always switch the tool off and remove the batteries before swapping rollers.
If near-surface soil compaction needs addressing, hollow tines are the more targeted choice. Solid spikes simply push soil aside. Hollow tools remove material, which loosens the treated area. A hand tool is enough for small trouble spots; for larger lawns, hiring a machine may be worthwhile.
Once a lawn has been core-aerated, the resulting channels only go as deep as the working depth used. If a poorly draining layer remains underneath, the area can still become waterlogged. If waterlogging keeps recurring, it's worth reviewing the whole soil profile.
A freshly raked or aerated lawn can look a bit rough at first. Clear away the last of the debris and check whether any genuinely bare patches have appeared. Where there was previously just dead material, open patches of soil may now be visible. Our guide to properly repairing bare patches shows you how to work suitable seed into these areas.
The combination of "raking, top-dressing and reseeding" is often recommended as a blanket routine. It's more sensible to decide based on actual need. After hollow-tine treatment, suitable washed, fine-grained lawn sand can help fill the newly opened pores. Grain size and quantity need to suit your existing soil profile. Spread it thinly and work it in with a broom without burying the grass blades. A thick layer of generic building sand won't automatically improve heavy soil.
If a nutrient is lacking, mechanical treatment alone won't fix that. Whether you should feed depends on previous feeding history, the time of year and, ideally, a soil test. Choose a fertiliser to match and stick to the manufacturer's dosage. For the start of the season, see our further advice on spring nutrition.
Water the treated lawn according to what the soil needs. For established grass, moisture should reach the root zone. Fresh seed, on the other hand, needs an evenly moist surface until the young plants have established themselves. Avoid puddling and washing seed away. Our article on watering during summer heat explains watering established areas in more detail.
Moisture for young plants
This adjustable sprinkler helps you water rectangular areas. When watering fresh seed, check surface moisture and adjust the water flow so seed isn't washed away.

A tool set too deep can damage healthy grass. When scarifying a lawn, the blades should only lightly touch the soil surface; deep tilling has no place in this job. Guidance from turf care bodies such as the STRI draws the same distinction between combing out loose debris and removing a troublesome thatch layer.
Impatience doesn't help either: if the ground is wet, extra foot and machine traffic may compact sensitive areas even further. And if you've just raked or aerated gently, the lawn needs time to recover. Treating it more often isn't a shortcut to a healthier lawn.
Keep an eye on your lawn regularly, rather than automatically repeating every treatment. A lush, green lawn comes from the right mowing routine, a suitable spot and consistent care. For a lawn that stays green all year round, this steady routine usually matters more than the next particularly intensive bout of machine work.
Raking uses springy tines to comb out loose debris from the grass surface, whilst aerating uses hollow tines to remove soil plugs and loosen the root zone beneath. Raking is a gentle surface tidy-up, whereas core aeration addresses compaction deeper in the soil.
Check for loose material that lifts out easily, or moss and thatch forming a solid mat. You can also do a spade test: if soil feels dense and slab-like, or if water sits there longer than elsewhere, compaction may be the issue. Look first, then choose the right treatment based on what you find.
Work on an established lawn during a mild growth phase, typically in spring or early autumn, when grass is dry for raking or when soil is evenly moist for deeper work. Avoid treating newly laid turf, heat-stressed grass or waterlogged ground.
Light raking can be repeated as needed depending on how much loose material builds up. You don't need a fixed schedule; on a healthy, well-growing lawn, extra passes bring no automatic benefit. Heavy use may require repeated soil attention, but this depends on your ground conditions.
Clear away debris and check for bare patches. You can top-dress with suitable lawn sand to fill newly opened pores after core aeration. Water the treated lawn according to soil needs, and consider feeding only if a nutrient is actually lacking, rather than as automatic routine maintenance.
Core aeration creates channels only as deep as the tool's working depth. If a poorly draining layer remains underneath, the area can still become waterlogged. If waterlogging keeps recurring, it's worth reviewing your whole soil profile to identify the root cause.
No. Deep scarifying with blades cutting into the soil can damage healthy grass and isn't the same as gentle surface raking or core aeration. Scarifying should only lightly touch the soil surface to remove thatch; this is different from tackling deeper compaction with hollow tines.
