To give some comparison, if you have lower pressure, for example, I had around 2 bar/28psi, and I managed to get around 415m2 with a 23m diameter.

Simply, screw onto your hose, adjust to either full 360 degree or part circle from 20 to 340 degree coverage and turn on the tap. However, if you have a bunch of different plants next to each other that will all benefit from different amounts of water, hand watering is obviously better. Not only is it a very efficient way of doing things, it also looks pretty cool and who doesn’t like to show a little?Hozelock’s Pro rectangular sprinkler brings you extras like a metal hose connector, sliders to control the oscillation range and a dial that switches the outer nozzles off for a tighter fan of water. Well, the sprinkler, which resembles a tiny 3-wheeled tractor, uses its front runner to follow any 5/8 inch hose that you lay down on your lawn. If you’ve got enough pressure this sprinkler will reach a range of 20m, either side, and even at a relatively lowly two bar of pressure you should reach up to 16m away. There are a few established garden sprinkler makers, as well as plenty of up and coming makers, that are producing products right now.

For example, while you can adjust the coverage of the 20 jets, you can’t switch them off individually like you can with the Karcher. Unfortunately, we didn’t get to test it out in cold conditions, but we can confirm that it drained most of the water out quickly.

Even among the best and most adjustable sprinklers, there are others that stand out, and for us it was the Karcher oscillating sprinkler pictured below . For even more information about this sprinkler be sure to read the Kärcher Premium Oscillating Sprinkler OS 5. The controls for changing the spray pattern are really easy to use too, and only require you to move a slider around. And once you have collected all the waste, easily manage them by reducing them to chips or mulch with the use of garden shredders.
