The Pros of Leaving Grass Longer in Hot Weather
Leaving your grass longer in hot weather can have several benefits. One of the primary advantages is that it helps to reduce water loss through evapotranspiration. When grass is taller, it shades the soil, reducing the amount of water that evaporates from the soil surface. This can be particularly beneficial in areas where water conservation is essential. Additionally, taller grass can help to prevent weed growth, as it shades out weeds and prevents them from germinating.
Another benefit of leaving your grass longer is that it promotes deeper root growth. When grass is taller, it has more leaf surface area, which allows it to produce more energy through photosynthesis. This energy is then used to promote root growth, making the grass more drought-resistant and less susceptible to disease.
How Taller Grass Affects Soil Temperature
Research has shown that taller grass can help to reduce soil temperature, which can be beneficial in hot weather. When the sun’s rays hit the soil, they can cause the soil temperature to rise, leading to heat stress and potential damage to the grass.

As a general rule, it’s recommended to leave cool-season grasses, such as Kentucky bluegrass and perennial ryegrass, at a height of 2.5 to 3 inches during hot weather. For warm-season grasses, such as Bermudagrass and zoysiagrass, a height of 1 to 2 inches is more suitable. It’s essential to research the specific needs of your grass type and adjust the mowing height accordingly.
It’s also important to consider the climate and weather conditions in your area when determining the ideal grass length. In areas with extreme temperatures, it may be beneficial to leave the grass even longer to provide extra protection and shade. Additionally, if you have a lot of shade in your yard, you may be able to get away with a shorter grass length. Ultimately, the key is to find a balance between maintaining a healthy lawn and achieving the desired appearance. By leaving your grass at the optimal height, you can enjoy a lush, green lawn while also reducing the risk of drought stress and other heat-related problems.
Will leaving my grass longer attract pests and diseases?
Leaving your grass longer in hot weather does not necessarily attract pests and diseases. In fact, a well-maintained lawn with adequate height can be less susceptible to pests and diseases. Tall grass provides a natural barrier against pests, such as white grubs and chinch bugs, which prefer shorter grass. Additionally, longer grass is less prone to disease, as it allows for better air circulation and reduces the amount of moisture that can accumulate on the blades.
However, it’s essential to maintain good lawn care practices, regardless of the grass length. This includes regular mowing, watering, and fertilizing, as well as monitoring for pests and diseases. If you do notice any issues, it’s crucial to address them promptly to prevent the problem from spreading.
