How often should you water the lawn?

Especially in early summer and in the summer months, lawns depend on a regular water supply to stay fresh, green, and healthy. The reason for this is the short roots of the grasses, which cannot get the moisture they need from the depths of the ground themselves when it is dry.

How much water does the lawn need?

If you consider that a lawn requires an average of around 2.5 liters (.65 gallons) of water per day and square meter (10SF), it is clear that the summer downpours are usually not sufficient for an adequate supply.

However, it is not possible to specify how high the actual water requirement is. Like so many other things, this is very individual and depends on various factors.

The following factors have a major impact on the moisture requirements of your lawn:

  • the composition of the lawn: different types of grass have different moisture requirements
  • Location : Lawns in sunny, warm, and windless locations usually need more water
  • Soil: In sandy soils, the water often seeps away very quickly, which is why the water requirement is higher here
  • the heavier and more loamy the soil is, the less it has to be watered
  • Load: the more the lawn is used, the better maintenance it needs

If possible, do not water in small amounts every day

Proper lawn care also includes watering the lawn thoroughly once or twice a week if possible. Don’t make the mistake of watering the area daily, but little: the amount of water is not enough to reach deeper soil layers.

Instead, the moisture stays at or just below the surface, which on the one hand promotes the matting of the lawn – and on the other hand, ensures that the roots also form just below the surface and therefore become dependent on a continued frequent water supply.

Then stop watering for a few days (e.g. because you’ve been away for a while) and the blades of grass will dry up quickly. It is, therefore, better to train your lawn to a weekly watering unit, at which you administer the weekly requirement.

Watering the lawn – this is how it’s done

A lawn needs between 20 and 25 liters (4-5 gallons) of water per square meter (10SF) per week, which should penetrate the soil about ten centimeters deep. After watering, you can take a few samples out of the lawn and check: If the top one or two centimeters are relatively dry, but the soil below is moist, you have done everything right.

If it is the other way around, the amount of water used is not sufficient or you grabbed the garden hose at the wrong time.

Tips

Install a rain gauge or other suitable vessel in the center of the lawn. If this is filled with water about two centimeters high, you have reached the required amount of water.

I studied horticulture at the University of Guelph and in my free time I plant everything that has roots on a piece of land. The topic of self-sufficiency and seasonal nutrition is particularly close to my heart. Favorite fruit: quince, corner, and blueberry Favorite vegetables: peas, tomatoes, and garlic
