Lawn care in high heat and drought

Also here we want to have summer, which gives an almost Mediterranean atmosphere, and what is not, can always be. But that’s not all garden users right again.

While many people are happy to sink into the next deck chair, the lovers of the well-groomed lawn are already anxious after a short time: If it stays so hot and still

does not rain longer, how is the lawn to survive that just healthy and good looking?

“Heat-free” for the lawnmower

When it’s really hot outside, the lawn can stay a bit longer. Because when the stalks are longer, the turf shadows itself, so to speak, and with this shading it evaporates less water. At least 4 inches high, the lawn should now remain, it may even be up to 8 inches high (in “normal” times the lawn should be kept between 3 and 6 inches high). If at some point you have to mow, and it’s still hot, you should start mowing the lawn in the evenings. Then it is a bit cooler, the interfaces do not dry out immediately and therefore can close better. You should then mow little, so that the blades retain their shadowing length.

Even if the heat period is over and the lawn can be mown again regularly, you should not immediately start a radical cut. It is better to cut the grass just a little bit shorter. A few days later, the next cut can be made, bringing the lawn to normal length (brevity). Because a cut of several centimeters at once would be a shock to the lawn, from which he would have to recover again.

Right blow

The lawn should not be watered under extreme heat when it is lit by the blazing sun. If you belong to the early risers, you should water the lawn in the early morning hours, then the ground is still cool, the water is optimally absorbed. If you do not dream of forcing yourself out of bed one hour earlier to blow up the lawn, you can also use the evening hours for irrigation. Maybe not right after the sun has just set, then the ground is still heated enough that much of the blasting water evaporates.

Incidentally, the lawn does not need to be watered daily, as many gardeners still assume. An intensive irrigation in a longer time interval gets the lawn better than frequent, superficial blasting. Normally, if you blow the lawn once a week, it will get water twice a week in the heat and dryness.

Then the lawn is really thirsty. Between 10 and 25 liters per square meter you should spend every time. How much depends on how deep the roots of the lawn go into the soil and if the soil is more clayey or sandy. Low-rooted turf in a sandy bottom can absorb less water at once than deep-rooted turf in a soil that holds the water for a while.

The necessary amount of water should be applied rather slowly, if you just flood the lawn, a lot of water just runs past the roots. In the DIN standard for irrigation of public lawns is spoken by a maximum output of 5 liters per hour. So if you want to water 10 square meters of lawn with a mean value of 15 liters per square meter, then this irrigation should take about 3 hours.

Overall, the sprinkler should distribute 150 liters to this 10 square meter, which happens when it is set so that it takes about 10 minutes to fill a small bucket of water. Of course, it does not depend on the liter, and the irrigation may certainly be slightly shortened in time, but the small calculation shows well that the lawn benefits the most when it is really raining slowly.

Incidentally, this type of irrigation not only helps your wallet because you save water. It also helps your lawn: A lawn, which is poured with a few drops every day, constantly suffers from lack of water. All roots will endeavor to stay as close as possible to the surface where the water comes up. Roots, which should actually go deeper, are at a disadvantage, the shallow roots among the grasses will prevail. In short: With daily, insufficient pouring you will break your lawn.

Do not fertilize in case of heat

Lawn needs fertilizer. As a rule, three fertilizers are recommended with a high-quality long-term fertilizer. Fertilization takes place once at the beginning of the season in April, at the peak of growth in June and towards the end of the season in August. Of course, there is a certain window of opportunity for each of these fertilizers, you should definitely only fertilize a dry lawn, otherwise the fertilizer sticks to the stalks and burns them.

Care should be taken even when it is very hot, a liquid fertilizer could burn the stalks as soon as they are applied. So better wait for the next covered weather, or fertilize the lawn very early in the morning. If you plan to fertilizer just before watering, you can be sure that the fertilizer will be flushed by the stalks.
