Gardena Premium Pulse Sprinkler Best garden sprinkler 2021T3 Award

1. Gardena Premium Pulse Sprinkler

The best lawn sprinkler

Specifications
Type: Pulse
Coverage: 490 Sq.M
Nozzles: 1
Reasons to buy
+Great for large gardens +Creates the sound of summer
Reasons to avoid
-Delicate construction

Aside from being especially well suited for large lawns up to 490m2, the main reason we love pulse or impact sprinklers is because they typify the sound of summer and especially the countryside. After all, who doesn’t love the peaceful tsk-tsk-tsk sound of a farmer or stately home’s irrigation system on a hot summer’s evening while sipping on a Pimms or going for a stroll along a bridleway? Well, plonk this model on your lawn and you’ll always feel like you’re in the country.

Admittedly, pulse sprinklers do look like the result of someone who’s found a jumble of metal and plastic bits and put them all together in a man shed. They’re also quite delicate and don’t like being trampled on. But they’re among the best options for long-range watering.

This Gardena Premium Pulse Sprinkler uses a decent amount of sturdy metal in its construction and comes equipped with a high precision brass nozzle that should produce a fusillade of reliable squirts day in day out. Its 10 to 25 metre range is easily adjusted using the large knob on the side and there’s a separate swivel adjuster to set the sector from 25˚ to 360˚. And because it has a through connector, you can also link a bunch of them together for a full-on squirt symphony.

Hozelock Rectangular Sprinkler Best garden sprinkler 2021

2. Hozelock Rectangular Sprinkler

The best cheap lawn sprinkler

Specifications
Type: Rotating
Coverage: 180 Sq.M
Nozzles: 15
Reasons to buy
+Sturdy design+Even coverage 
Reasons to avoid
- Expect to get wet when setting up  

Smaller gardens that need a reliable job done can expect good things from this side-to-side sprinkler. Indeed, it’s arguably the most popular sprinkler on the market and very reliable it is, too. Unlike the Kärcher and Gardena reviewed below, you can’t make any adjustments to the 15 water jets but you can adjust the reach on either side. However, making reach adjustments on the fly is recipe for a good soaking so be sure to time your tinkering Ethan Hunt-style between oscillations.

The Hozelock’s wide sledge-style design keeps it firmly in place even on steep inclines so perhaps consider it if your lawn is as hilly as the South Downs and preferably rectangular in shape.

3. Karcher Premium Oscillating Sprinkler OS 5.320SV

The best premium lawn sprinkler

Specifications
Type: Oscillating
Coverage: 320 Sq. M
Nozzles: 20
Reasons to buy
+Impressive design+Exceptional versatility
Reasons to avoid
- Requires decent water pressure

Kärcher is best known for its pressure washers but it’s also into gardening in a big way and doing it well. Take this sturdy oscillating sprinkler for example. Unlike your average common or garden oscillator, this one comes with a full complement of bells and whistles. It’s got twenty jets on board for a start, and that means excellent coverage on all sides. Better still, you can customise the coverage by turning off some of the nozzles on either side to produce a narrower zone.

The Kärcher Oscillating Sprinkler also comes with a knob for adjusting the water pressure so you don’t need to stand at a tap while selecting the most suitable squirt distance. And, in a minor stroke of genius, there’s a plastic SplashGuard underneath the unit that rotates to cover the jets nearest to your face while you make extra adjustments.

Admittedly, with all nozzles open – and using typical London water pressure – the Kärcher isn’t as far reaching as the Spear & Jackson or Hozelock Rectangular Sprinkler (you get about 4m of soakiness either side) but close a couple of jets on both sides and the throw increases to around 8m either side, albeit with a narrower formation. This setting is ideal for the average long and slim urban London lawn since it will cover the entire plot in one fell swoop. And that means you can just leave it to do its stuff while you engage in more important pastimes, like stuffing your face and getting rat arsed.

4. Spear & Jackson BWF22 Oscillating Sprinkler

Best sprinkler for reach and build quality

Specifications
Type: Oscillating
Coverage: 340 Sq.M
Nozzles: 18
Reasons to buy
+Superb all-metal build+Brass nozzles+Massive reach

Constructed entirely out of metal with 18 brass nozzles and brass hose connector, this oscillating sprinkler surprised us with its coverage, especially since London’s mains pressure can sometimes be so woefully low.

We fired it up and had to run for cover because it covered the entire length and width of the garden (10 x 7 m) in one go. Not even the excellent Karcher above achieved that level of coverage. Aside from adjustable angle of flow and a little pressure dial that controls its reach, it doesn’t come with any fancy bells and whistles. If you want more adjustability in all areas then the Kärcher is still our favourite choice, but if you just want an incredibly well made pro-spec oscillating sprinkler that covers a really wide area in one go, then this is the one to plump for.

This model frequently sells out, so also consider the Spear & Jackson Kew Collection sprinkler.

Gardena Oscillating Sprinkler AquaZoom M Best garden sprinkler 2021

5. Gardena AquaZoom M

Adjustable sprinkler with bigger waterdrops for smaller lawns

Specifications
Type: Oscillating
Coverage: 250 Sq. M
Nozzles: 16
Reasons to buy
+Adjustable nozzles+Produces larger drops of water
Reasons to avoid
-Not very good lateral range

Like the excellent Kärcher reviewed above, this new Gardena model’s 16 water jets can be adjusted for either a wide or narrow reach depending on the size and shape of the garden. However, unlike the Kärcher’s 20 nozzles which you can switch on and off, the Gardena’s system uses two banks of permanently on nozzles which can be aimed side to side to provide a narrow or wide zone, or even adjusted so one bank of jets forms a straight line, say down the edge of a pathway, while the other bank waters the rest of the lawn plus perhaps a flower bed on the side.

The Gardena’s nozzles are wider than the norm and that means the reach is nowhere near as far as the supreme Spear & Jackson or Kärcher with two of its jet banks turned off. On the plus side, the increased amount of water coming out of each jet is very similar to that of rain drops so in many ways this sprinkler provides more water per squirty oscillation.

The upshot is, if you have a garden with a surface area larger than say, 10m x 5m or your water pressure is low as it usually is in London, then perhaps forego this model and opt for the Spear & Jackson which has massive range even in low-pressure regions. On the other hand, if your lawn is relatively small – and oddly shaped – and you wish to douse the lawn and beds with more water per pass, then this is the sprinkler to go for.

Hozelock Round Sprinkler Pro Best garden sprinkler 2021

6. Hozelock Round Sprinkler Pro

Best garden sprinkler for unusually low or high water pressure areas

Specifications
Type: Rotating
Coverage: 314 Sq.M
Nozzles: 5
Reasons to buy
+Large area coverage +Secure fit 
Reasons to avoid
-Sometimes the hosepipe comes loose

Hozelock has another great entry on our list with the Round Sprinkler Pro which users have found works incredibly well regardless of your water pressure. The spike design means it can be placed securely in the grass and on even the steepest of inclines, or you can purchase the same model with a sled base instead.

With its choice of five nozzles, this sprinkler can be set to complete a full circle of coverage (up to 20m in diameter) or a wide arc by simply adjusting the red setting ring. It is also said to be excellent for providing spray coverage across the whole garden or targeting specific areas with a stronger flow. An excellent choice for smaller lawns.

7. Gardena Turbo-driven Pop-up Sprinkler T 100

Best pop-up lawn sprinkler

Specifications
Type: Oscillating
Coverage: 100 Sq.M
Nozzles: 16
Reasons to buy
+Pops up out of the ground +Good coverage
Reasons to avoid
-A right pain to install 

If you don’t like the idea of a sprinkler taking up room on your lawn, then this integrated sprinkler is the ideal way to overcome the issue. Because it’s hidden, this lawn sprinkler does require installation – a 10-inch hole will need to be dug along with a trench for the hose.

The Popup comes with 16 flexible nozzles to ensure even water distribution and is particularly effective on rectangular shaped lawns (you can adjust spray width, range and direction by fiddling with the unit’s various knobs and wheels). To use, simply turn on the tap – or have a timer do it for you – and the water pressure causes it to pop up out of the ground. When finished, it descends back into its housing.

The Popup is far and away the most aesthetically pleasing model on the page but be warned that some users may find they don’t have high enough water pressure for it to reach all areas. We would suggest trying an ordinary sprinkler first to test for general reach, because the last thing you need is to discover it has woeful coverage after having dug up half the garden. You’re also advised to have the system installed by a professional landscaper because the scant instructions are, to put it bluntly, awful.

How to buy the best garden sprinkler for you

Watering your lawn by hand isn’t too much of a hardship, but if you have a large garden then this can begin to take up a lot of your time. This is where a lawn sprinkler comes in.

There are a few types of sprinkler you can get, and the one you choose will depend on the shape and size of your garden, and if there are any particular areas you want covered. A fixed sprinkler will simply water one chosen area but they are usually good at getting to those hard-to-reach areas.

Rotating and oscillating lawn sprinklers will ensure different areas of your garden are watered evenly and tend to be gentler on flowerbeds.  However, if you have a particularly large garden, then travelling sprinklers work by moving up and down your lawn to ensure even coverage.

For the most efficient and effective watering, a lawn sprinkler attached to an electronic timer will ensure consistent maintenance, and opting for a sprinkler with a range of nozzles and flow settings means you can target certain areas that need more attention.

Our top choices for ground-based sprinkling include the multi-faceted Karcher Oscillating Sprinkler, the robust and far reaching Spear & Jackson BWF22 Oscillating Sprinkler, the new Gardena Oscillating Sprinkler AquaZoom M and the classic Hozelock Rectangular Sprinkler, or Lawnqueen as it was once known.

What is the best time to water your garden with a sprinkler? Plus other garden sprinkler tips.

As with watering anything the optimal time to do so is in the morning. By turning on your sprinkler in the morning you help the plant or lawn to retain the water that is deposited on it, rather than it evaporating.

If you're watering a lawn then, on average, it is advised to use your sprinkler once a week or a couple of times per week in prolonged dry weather, and to deposit about an inch of water over it. This takes roughly an hour, but obviously varies between make of sprinkler.

One question to remain mindful of, though, is "do sprinklers use a lot of water?" because the answer is yes. This is why it is important to make use of a sprinkler at the optimal times of day to increase its effectiveness in a given time.

It is OK to water plants and lawns in the evening and night, too, however again this needs to be in a controlled manner as damp leaves or boggy ground encourages fungus, moss and mold, which is detrimental to the health of the lawn or plants. This is why watering in the morning is most optimal – the plants absorb the water and make use of it during the peak sunlight hours of the day, meaning they are dry come nightfall.

Lastly, addressing the age old hand water vs water sprinkler argument, both forms of watering have their time and place, as well as benefits. For example, if you just need to water a large patch of lawn or a crop of the same plants, then a sprinkler is a great solution. It waters everything evenly and with close to zero effort from the gardener. However, if you have a bunch of different plants next to each other that will all benefit from different amounts of water, then hand watering is obviously better. Hand watering also lets you water things in tight areas without getting things like paths and flagstones all wet and slippery.
