Lawn watering: The best tips and tricks

The Content Of The Article:

The right kind of lawn irrigation is crucial to whether or not you can call a dense, rich green lawn your own. Strictly speaking, however, the showcase green is a pure artifact whose countless blades of grass, growing close together in monoculture, therefore need special care. This applies to the fertilizer - it should be three times a year - but also for the lawn irrigation. Here you will find our best tips and tricks.

So you realize that the lawn needs water

It will be time for the lawn irrigation, if the stalks do not reestablish themselves after 15 to 20 minutes after entering. But do not spoil the lawn constantly with small sips that infiltrate only a few inches deep into the ground. In that case, the grasses do not feel like sending their roots deeper into the soil, where they could also make use of the water supply from deeper layers. Pampered lawn makes it dull in the drought - even a short break can ruin it. To force the grasses to form long roots, you water less often, but extensively. For clay soil once a week, for sandy soil every four days.

If a lawn is not watered enough, it quickly becomes unsightly and weeds spread

The right time to water the lawn

In principle, you can water your lawn at any time of the day, even in the blazing sun, which even cools the lawn. Damage caused by the so-called burning glass effect belongs to the realm of fairy tales. The lifetime of the drops is much too low and a concentrated heat jet under water is not possible. However, if the water does not drift quickly enough into the soil, part of it evaporates unused, which is why the morning hours for watering the lawn are ideal.

It depends on the ground

Different types of soil require a different type of lawn irrigation. If grass grows on sandy soil, it can not hold the water and is therefore most affected by dryness. Grass on loamy soil survives even longer drought and then drives out again willingly. However, you should not allow it, because thirsty grass is quickly conquered by weeds, which cope better with the dryness and then spread very quickly. On sandy soils, you can create additional storage space for water and nutrients with water-storing aids such as bentonite. They simply sprinkle the fine powder on the lawn and let it carry rainwater into the ground.

Irrigation time and amount of water


A rain gauge is useful for measuring the amount of water per square meter

Lawn needs a good 15 liters of water per square meter in summer. This amount moistens the soil 15 to 20 inches deep. You can not say a blanket, how long a lawn sprinkler must run for it. This depends on the water pressure of the pipe, the type of sprinkler and the type of soil. However, the individual irrigation time for your lawn is easy to estimate: set up a rain gauge and remember how long your lawn sprinkler has to run for 15 liters. Alternatively, use the spade to pierce a pyramid-shaped piece of ground with three targeted stitches and check after which time the soil is moistened 15 cm deep.
Tip: Allow the lawn to stand longer before a heat wave is expected, and do not mow it in heat. The stalks look like small umbrellas and obstruct the evaporation of water from the ground - the lawn lasts longer.

Means for perfect lawn irrigation

Irrigate lawn by hand

Irrigation with the hose makes little sense for larger lawns

Hose or lawn sprinkler? This question only arises with small lawns. With larger irrigated nobody more with the hose, there lawn sprinklers prevailed. And they come in many variants, from simple to high-tech, fixed or mobile. It does not matter if adjacent beds are partially irrigated. Only flowers should not be taken directly.

Retractable sprinklers

Fixed, usually retractable sprinklers are supplied via underground water pipes. Turning on the pipe, it says "water march!" and the pop-up sprinklers automatically move out of the ground at the appropriate water pressure. The sprinklers can be combined with irrigation computers, integrated with control modules in the smart lawn irrigation and controlled by app - even from vacation

Lawn watering with sprinkler

Somewhat elaborate, but smart: lawn watering with retractable sprinklers

However, pop-up sprinklers are set to a certain area. If the use changes or if you want to redesign the garden, you will have to re-install it. Whether fully automatic irrigation is an option depends, among other things, on the performance of the water pipe.If it has too little pressure, you have to irrigate the different garden areas one after the other. You can easily determine the pressure yourself by measuring how long it takes for a 10-liter bucket to run under the tap full of water. If it takes more than 30 seconds, it can get tight.

Classic square and circle sprinklers

The choice of lawn sprinkler generally depends on the size of the area and the shape of the lawn. For almost rectangular lawns is a classic rectangular sprinkler, for roundish there are circular sprinkler. Both can also be set in sectors, so that they irrigate only one-sided or a certain area. There are also high-tech lawn sprinkler models, where you can preset different casting distances as in the "AquaContour" from Gardena and then adapt to the lawns as exactly as possible. Even irregularly shaped lawns are irrigated to the rim, without having to move the device.

Lawn Irrigation Sprinkler

Circular sprinklers are ideal for irrigating large lawns

Circular sprinklers cover larger surfaces with their rotatable arms than the square sprinklers. Special forms are sprinklers that eject a barrage of fine drops of water and are thus ideal for lawns on slopes, since the water can slowly seep away and does not flow off unused on the surface. However, sprinklers irrigate only smaller areas. Impulse sprinklers have the greatest area coverage at the corresponding water pressure, but should not be in the immediate vicinity of the plant. In these models, the nozzle is installed on a central pivot.

Put on solid grass from the beginning

Those who want to create new lawns and spend as little time as possible on lawn irrigation should opt for sturdy lawn mixtures right from the start. Because grass seed is always a mix of different types of grass, which determine the properties of the lawn with their respective share of each species. There are special grass mixtures (Kiepenkerl, Wolf garden) with a high proportion of deeply rooted grasses that cope better with dryness than other species. The color of these grasses is a bit lighter.
