How Do I Take Care Of My Lawn In The Summer?

Your lawn has to cope with different challenges in every season. In summer, periods of heat and intense rainfall are the main challenges. If you do not take this into account, there is a risk that your lawn will die and bare patches will form.

This overview shows you which lawn care is necessary in summer and how to go about it. Then you will be optimally prepared for the hot days and your lawn will survive this difficult period.

What are the challenges in summer?


In spring, everything is geared towards growth for the lawn. The lawn awakens from hibernation and the first rays of sunshine make the lawn soar. Summer, on the other hand, is all about making the most of your lawn and avoiding weak spots. With proper care, you want to maintain the high quality without the weather extremes causing any damage. The following factors put a strain on lawns in the summer.

Heat


Warm temperatures are actually positive and a requirement for a lawn to feel comfortable. However, during the summer heat, temperatures can reach levels that become a problem.

Above a temperature of 25°C, most grasses stop growing. This happens out of self-protection. Because this heat means high stress for the plants. They have to take up more nutrients and water to counteract evaporation. Your lawn will grow much slower in the summer, and you need to take this into account when mowing your lawn.

Greater precipitation


Summer doesn’t just wait for your lawn with warmer temperatures. In the evening, when the hot air cools down, you can expect more precipitation. These are so heavy that the soil is hardly able to absorb these amounts of water. There is a risk that waterlogging will form on the lawn, endangering the greenery.

Likewise, when watering, you must make sure that the amount is adjusted to the precipitation. So check the weather forecast regularly or even better, use a weather station for your garden. Then you will not have a nasty surprise and the grass will not be over-watered.

Garden activities


When caring for your lawn in the summer, you also need to take into account that you will be spending more time in the garden. While in spring the days are still shorter and colder, summer invites you to spend time on the lawn.

Whether it’s because you’re hosting a casual barbecue or kids prefer to play outside. As a result, your lawn is subject to more wear and tear in the summer, which you need to take into account when caring for your lawn in the summer.

Mow the lawn

A cornerstone of a well-groomed lawn is mowing. As soon as the lawn starts to grow, you need to ensure the optimal lawn height with the lawn mower. Otherwise, the lawn is vulnerable to weeds and will not be able to stand up to the larger influences.

In the summer you need to mow the lawn a little more often. At least, if it is still growing and temperatures do not regularly exceed 30°C.

Mowing is necessary about every 4 to 7 days. The deeper the cut, the higher the load on the lawn. Therefore, it is recommended to mow more often and not to remove so much of the plant.

For the summer, a cutting height of 5 to 7cm proves to be ideal. This makes it more resistant and reduces the risk of water shortage.

The right fertilizer for your lawn in summer


Choosing the right fertilizer is important for lawn care. Depending on the season, different nutrients are needed to keep lawns at their best.

Pay particular attention to the color of the lawn. If it turns yellow, bald patches form or growth is inhibited, the cause could be a nutrient deficiency.

In the spring you can use a fertilizer, which helps especially in the short term and provides the necessary nutrients for growth. With this, the lawn is well supplied and will grow in height.

During the summer, on the other hand, a combination of immediate and long-term action is preferred. The goal here is not for the lawn to grow up quickly, but to become more robust.

If your lawn appears weak and shows slight discoloration, then rely on a complete fertilizer. This is equipped with these nutrients:

  • Nitrogen (N) – Important for growth and green coloration.
  • Phosphorus (P) – Favors the growth of the roots
  • Potassium (K) – Strengthens the resistance of the lawn


If you apply the lawn fertilizer for the summer, you should notice a significant improvement after about a week. With a long-term effect, the lawn in the summer is still optimally supplied after about 2 months, so you have little to worry about in terms of maintenance.

With the lawn fertilizer for the summer, make sure that the nutrients are present in the correct ratio. A slightly higher proportion of potassium is beneficial so that the grass survives the summer better.

In addition, adhere to the dosage recommendation. Otherwise, you could end up overfertilizing the lawn and doing it more harm than good.

Starting in September, a lawn fertilizer for the fall is a better choice. This has hardly any more nitrogen and relies on a higher potassium content. As a result, the lawn is better prepared for the coming winter.

Optimal watering


As a third factor, irrigation presents you with some requirements that apply specifically to summer. Are you afraid that the strong sun will cause the plants to dry out but at the same time “burning” may occur?

When it comes to watering, there are indeed some things you need to consider when caring for your lawn in the summer. If you don’t do it thoroughly, fungus and moss can spread in the lawn, crowding out the grass.

Water in the morning or evening

Basically, you should avoid the hot midday hours to water the lawn. The water evaporates and hardly penetrates into the soil.

In the morning it is still a little cooler and the water is better absorbed by the roots. If you water the lawn in the evening, you should reduce the amount slightly, as the temperatures are cooler.

Frequency


If the temperatures are rather mild and in the range of 20°C, one watering session a week is sufficient. If the temperature rises noticeably, switch to watering the lawn at least twice a week. This will keep the soil and grasses moist throughout without drying out completely.

Application rate


An amount of 10 to 15 liters per m² of lawn area is appropriate per watering session. Test the soil with a spade. If the soil is still slightly moist even at a depth of 15cm, apply enough water. If the soil is too dry, apply a larger amount or set up the sprinkler more often.

Can your lawn burn?


Time and again, there is a rumor that lawn care, and especially watering in the summer, runs the risk of burning the lawn. But is this fear justified?

The idea behind it is that the water droplets on the blades of grass act like a magnifying glass. This would focus the sunlight and affect the grass with a higher intensity.

However, this kind of burning belongs to the realm of myths. It is true that watering during the hot midday hours should be avoided. However, this is more related to the fact that much of the water evaporates and is not absorbed by the roots in the first place. If you have no other way to water the lawn, you can do it during the midday hours before the drought causes any damage.

On the other hand, it is correct that you should take care of your lawn during the summer heat. In the spring, choose suitable seeds that are hardy and cope well with the sun. Then burns are not expected and weeds have little chance to spread.

The optimal lawn care in summer


If you want to enjoy time in the garden in the summer, special care is necessary for this. Let the grass grow a little longer, carry out watering more often and make sure that it is supplied with sufficient nutrients.

Give the lawn a break when the grasses start to turn slightly yellow and bare patches start to form. With a little care, you’ll also be able to weather the summer heat as well as heavy rain showers.

It is also helpful to have a watering computer, which will supply the garden while you are on vacation. This will allow you to easily take a break from maintenance for a week or two and not have a nasty surprise when you return.
