Are you a proud owner of an alluring, well-kept lawn? Wondering how often to water grass in hot weather as summer approaches? This is an issue that often arises, particularly as temperatures start to sink across the country.

How often to water grass

As lawn owners, we have to think about how to change our lawn watering routine so that our grass remains vivid green all year round. Unfortunately, in the heat, no perfect one-solution-fits-all approach is available to water the garden. 

How much water your garden needs depends on a variety of factors such as how much shade it gets, the sort of soil you have and the type of grass you are growing. Usually, a shaded garden, or one with clay-based soil, does not require much water compared to the new lawns with sandy soil and direct sunlight.

As a general rule of thumb, you should water the new grass two to three times a week throughout the hot summer months, especially if there is a lack of rainfall. Usually, you should water the fescue grass almost 3 to 4 cm using a sprinkler– it works great.

In areas with a lot of sunlight, you may have to water more frequently.

Ideal Time to Water the Grass

The optimal time of day to water a garden is in the early morning between 4 to 9 a.m. An early application permits the water to penetrate the soil deeply, and very little water is wasted due to evaporation.

If you water the grass in the middle of the day, it will evaporate quickly. Moreover, if you live in a windy, breezy area, they will result in uneven water distribution. Strong midday breezes can also bring the water onto roads or sidewalks, wasting large quantities of water.

If you water the grass in the late afternoon or the evening, it allows pests, fungi, and other water-borne diseases to propagate.

Cool-season grasses like Kentucky Bluegrass may withstand extended periods of dry weather. When the weather is dry, the grass falls asleep. Dormancy is one of the natural turfgrass survival mechanisms. 

While the leaves become brown & withered, the roots & crowns of the turfgrass remain alive. Kentucky bluegrass may often remain dormant for 4 to 6 weeks without any substantial harm.

Responsible garden watering

Now that we have discussed how often you should water grass in warm weather, let’s talk about ways to reduce the overall water usage. This article is a wonderful opportunity to discuss how you can decrease the usage of outdoor water. 

EPA says that you can use up to 60% of your home water on your garden for watering the grass. According to statistics, 50% of water is wasted due to overwatering. In summers, families consume over 4,000 litres of water each day

This is comparable to letting the garden hose run straight for 8-9 hours to give you a perspective. This is not only harsh on your pocket but is bad for the environment as well. Therefore, ensure that you use less water when you irrigate your lawn.

Tips for watering your garden in hot summers

Individuals have two fundamental choices in the face of hot, dry weather. One alternative is to do nothing & let the grass sleep. The other alternative is to irrigate the turfgrass in dry times to preserve a green & active garden.

With the help of a few easy summer watering tips that you use to conserve water & your money. These tips are very simple, easy, and straightforward. Following are 12 tips to keep your grass healthy in the summers.

1. Make the Soil Water-Friendly.

As mentioned before, sand-based soil doesn’t hold water well. It can absorb water for a while, but it can’t store it. Clay soil, on the other hand, performs an excellent job of storing water for a while.

However, pure clay soil is not suitable for plant roots. Therefore, you have to create a mixture of clay and sandy soil in your garden. To loosen the soil & enhance its absorption rate, add compost and mulch

2. Water the Grass Early in the Morning

During the warmest part of the day, you cannot conserve water if you sprinkle water on your grass since the water will evaporate immediately. In addition, the grass in your garden may be more prone to further fungal infections, depending on where you reside.

Experts thus advise that you should water your garden early in the morning. Set the timer somewhere around 4 am – 9 am for the best results if you have a sprinkling system.

3. Go for Organic Lawn Care

Use natural and organic fertiliser to help the soil absorb and store more water. Moreover, an organic fertiliser will make the grassroots strong, which will allow them to hold water for a more extended period.

4. Plant the Right Kind of Grass

In sun-exposed regions, plant “full sun grass” in sunny areas & “shade grass” in shaded places. You will use more water to keep the grass alive if you plant “shade grass” under full sun. 

Note that the location in which you reside influences the kind of grass seed you’ll be buying. For warmer regions, buy grass species that can survive high temperatures. Similarly, if you live in an area with cooler temperatures, you have to buy grass that can thrive in harsh weather conditions

Moreover, mow your grass regularly so that it can have a healthy root system for storing enough water.

5. Sprinkler Maintenance

Don’t forget to get your watering system professionally checked in the spring. You should also consider hiring an irrigation contractor that checks your irrigation system to ensure that every element works fully to provide optimal results.

If you have oscillating sprinklers, the latest technologies should help you re-calibrate it. Some Bluetooth controls, timers, moisturising sensors & mini-weather stations can help maintain optimum water levels in your established lawn.

Most gardens need almost 3 to 4 cm of water to remain lush green in summers. Adjust your sprinkler system in such a way that it sprinkles out the necessary amount of water only. Moreover, if you live in a region with high rainfall, you will have to make water adjustments accordingly.

6. Rainwater Harvesting

You may collect rainwater in watering cans if you reside in a region that regularly gets rainfall in the summer. You may also consider putting your drainage pipes right next to your garden, allowing water to flow from your home into the lawn.

7. Reduce your garden space

If you reside in a region that is prone to drought, you should consider reducing your lawn area. Yard grass needs a lot of water to survive & in dry regions, it may not be worthwhile. 

Instead, you may use artificial grass, meadow grass, indigenous plants, stones, hardscapes & more to decrease the amount of water. Avoid frequent applications of light water treatments as that encourages flaccid roots & exuberant growth. Shallow root turf grass is less resistant to drought. It is also more vulnerable to pesticide issues. 

Moreover, homeowners should place two or three rain gauges on the lawn to keep an eye on the quantity of water you spray into your healthy lawn.

How Often to Water the Grass in Hot Weather – Final Word

In summers, grass turns brown and starts to die if you don’t water it properly. Usually, you have to water your grass about 4 to 5 cm, twice a week. If the temperatures are high and you deem it necessary, you can water your grass three to four times a week.
