Regular watering is important for a healthy lawn. When is the right time of day for this depends on various factors and also how you use the lawn.

In a nutshell

  • Water new plants several times a day
  • water preferably in the early morning hours
  • only water in the evening in exceptional cases
  • evening watering promotes fungal infections and snail infestation
  • Irrigation systems automatically water at the right time using timers, for example

Water new plants several times

A newly laid lawn is a particular challenge when it comes to watering. The tender seedlings and the first stalks are particularly sensitive to drought. This does not only apply to areas that you have planted with seeds, turf is also very sensitive in the first few weeks until it takes root in the ground.

New plants must therefore remain constantly moist and you should water them at least twice a day, in the morning and in the evening. In the evening, the earth should have cooled down a bit so that the temperature difference between the water and the ground is not too great. If you water in the morning, make sure that there are no more drops of water hanging on the delicate stalks by midday. You should have watered between seven and eight o'clock at the latest.

Tip: If you create a new lawn, integrate irrigation systems right away. Modern systems are equipped with sensors and they regulate themselves and water the lawn automatically when necessary.

watering in the morning

The ideal time to water the lawn would be between three and four in the morning. If you don't have an irrigation system, you will rarely water at this time. You should water the lawn by late morning at the latest.
Benefits of morning watering:

  • fewer snails
  • lower risk of fungal diseases
  • maximum amount of water available for grasses
  • no temperature shock from the irrigation water

Very little water evaporates during the night hours or in the morning and the ground has almost the same temperature as the water. As a result, almost the entire amount of water that it received when watering is available to the lawn and can be absorbed by the grass through the roots.

watering in the evening

Watering the lawn in the evening involves risks and you should only water in the evening in exceptional cases.
You can water in the evening in the following cases:

  • after heavy pruning
  • when applying fertilizer
  • after selective new plants or repairs of the grass surface

If you have used the lawn to an above-average extent on one day, you could also water it in the evening. The lawn has the opportunity to recharge its batteries immediately after the load and the roots are already absorbing a lot of water at this point.

Notice: Only water the lawn in the evening if too much of the grass has not snapped off or been severed as a result of the wear and tear. You should also not water after mulching, because in both cases the severed stalks encourage the colonization of fungal diseases.

use irrigation systems

Irrigation systems are a great help in the correct watering of the lawn. These smart gardening helpers are now so intelligent that they can take over watering once they are connected to the tap.

When choosing an irrigation system, you should pay attention to the following points:

  • programmable timer must be available
  • fully automatic systems must have sensors for soil moisture and temperature
  • pay attention to the expandability of the system

frequently asked Questions

How long does the lawn need to be watered?

You should water the lawn for a maximum of 15 minutes.

Why can't the lawn be watered at midday?

The fine drops on the stalks act like a magnifying glass, especially at midday when the sun is at its highest. This literally burns the sensitive stalks.

How often does the lawn need to be watered?

It is sufficient if you water the lawn once a day. You only have to water new plants more frequently so that the burgeoning grass does not dry up.
