A green lawn in the garden is a declared goal for many hobby gardeners. And it is weeded and mowed so that the lawn in the garden resembles a golf course. A green, well-kept lawn looks good, but the question arises as to how this goal can be achieved while using less water. Lawn sprinklers are one way to quench the lawn's thirst and limit water consumption.

Lawn sprinkler criteria
A lawn sprinkler is not always the same as a lawn sprinkler. Nowadays they are available in a wide range of price ranges and the blasting behavior is also different.
A distinction is usually made between:
- square sprinkler
- circle sprinkler
- pop-up dispenser
Other criteria for blasting are:
- the irrigated area
- the range of the sprinkler
Depending on the sprinkler, the sprinkled area can be a circle, semicircle, ellipse, square or rectangle. Which sprinkler you choose ultimately depends on yours lawn area away. Because with all variants there is of course the choice of the size of the area to be irrigated.

water consumption
sprinklers and water consumption
The actual usage of a lawn sprinkler depends on how much water you put into the sprinkler. This is best done with a conventional water hose to compare. Depending on how much the tap is turned on, the more water runs through the hose and is therefore consumed. The water regulation or consumption must therefore be carried out manually. It is important that the water flows under sufficient pressure to the sprinkler. This is the only way to achieve the appropriate range.
Manufacturer
This may also be a reason why many manufacturers water consumption not specified for individual sprinklers. As a rule, however, you should calculate with a minimum of 600 to 800 liters of water per hour. A proper lawn sprinkler uses an average of 15 liters of water per square meter.

In the list you will find the consumption for selected lawn sprinklers:
- Gardena 2082-20 Classic square sprinkler Polo 220: 1,100 liters per hour
- Gardena Premium square sprinkler 250: at 2 bar: 800 liters per hour; at 4 bar: 1,200 liters per hour
- full circle sprinkler perrot ZA 30/4 mm: 690 to 1,890 liters per hour, depending on the water pressure
- full circle sprinkler perrot ZA 30/6 mm: 2,220 to 3,390 liters per hour, depending on the water pressure
- HUNTER Pop-up sprinkler I-40-04-SS ULTRA (for very large areas): 1,590 to 6,250 liters per hour, depending on the water pressure
- Eurom(R) Circle and sector sprinkler 1/2 inch: approx. 1,200 liters per hour
- agroflora Circle sprinkler, sector sprinkler 1/2 inch: 850 to 1,180 liters per hour
Tip: The guide values are 15 liters of water per square meter for sandy soil and 20 liters for clay soil per watering, so that the lawn is well supplied with water.

To control the water consumption, it is advisable to install a water meter. This puts you in control of water consumption and ultimately over water costs. Stiftung Warentest recommends placing three coffee cups under the sprinkler. Once they have filled with two centimeters of water, you can turn off the sprinkler, because this water level corresponds to about 20 liters of water per square meter of lawn.

regularity
How often to blast?
Closely related to water consumption is the question of how often the lawn should be watered when it's not raining. Here, too, a distinction must be made between sandy and clay soils. There clay soils which store moisture better than sandy soil, the lawn sprinkler should be used once a week on clay soil. lawn up sandy soils is thirstier, here you should blast every three days. Too much water is just as bad for the lawn as too little water. The rule here is that less is more, because if there is too much watering, the roots of the lawn remain flat, which in turn makes the lawn more susceptible to drought and heat.
Tip: If you irrigate the lawn in the evening, the water can seep into the ground well.
