"Summer Lawn Survival Guide: Cutting Your Grass in the Hottest Months"

Extreme heat can be taxing to both people and lawns alike. Unfortunately, that 64-ounce bottle of water you consumed won't satiate its thirst either.

Solution: Allow grass to become longer so it has deeper roots to absorb moisture and provide shade to prevent evaporation. However, doing this requires some patience and expertise.

Don't Mow Too Short

An immaculate lawn is lovely to look upon; however, it is essential to remember that short-cutting it too short could harm its health irreparably. Healthy grass needs long roots that reach deep into the soil to soak up moisture from rainstorms; cutting too short would force roots into only shallow reserves, leaving your yard without essential nutrients in summer heat conditions.

An attractive lawn with the ideal height will be less vulnerable to drought stress, disease, weeds, insect infestation, and other issues caused by hot weather. To achieve this goal, maintain regular mowing, watering, and lawn fertilization activities - it's also wise to periodically sharpen the mower blade midseason to reduce stress on your grass.

Cutting their lawn too short is a common mistake by many individuals who mistakenly believe it will save time and allow for longer between mowings. Unfortunately, doing this will damage its quality, leading to further problems requiring more work and expense later on.

Cutting grass too short puts undue strain on its energy levels as it can no longer produce leaves for photosynthesis, forcing the lawn to draw on its reserve energy stores for sustenance, which depletes vital nutrients and causes yellow or bare blades. Repeated shortcuts could leave weak and unhealthy grass more vulnerable to drought, disease, and pest attacks.

As summer temperatures heat up, experts advise mowing grass by the one-third rule to decrease scalping risks and promote healthier lawns. Mowing during cool parts of the day - early morning or late afternoon - may further minimize stress and evaporation effects on grass plants.


Don't Mow Too Much

As the heat of summer approaches, lawns can experience unprecedented strain from scorching temperatures, pest infestations, foot traffic, and disease. One way to add stress is through overflowing; this may damage your grass and lead to unsightly brown patches that will take time to repair.

As a rule of thumb, cutting one-third of your grass' height at any time is recommended to ensure it does not become stressed and starved of essential nutrients to survive and thrive. Overmowing causes the grass to focus on growing on top rather than feeding its roots for support, creating weak lawns vulnerable to drought and heat stress.

When trimming grass too short, you risk cutting off its most vital parts and weakening it overall. Therefore, it is vitally important that you know the optimal mowing height for your type of grass; ideally, this should occur weekly throughout the growing season for the best results and ensure your lawn remains strong enough to withstand heat stressors.

Trimming a lawn with tall grass may require shaving off over one-third at once to reach your desired mowing height. To do this more efficiently and gradually reach this target height, consider doing this step-by-step by gradually raising the mower height until reaching the desired mowing height.

As part of helping your grass manage the heat of summer, it's advisable to water it properly. Watering deeply while minimizing evaporation will keep it healthier and stronger against extreme temperatures and stressors such as drought. For optimal results, early morning or late evening irrigation should be utilized; this will decrease evaporation while increasing moisture absorption into your lawn and strengthening root systems making them more tolerant to harsh conditions.

Don't Mow at the Wrong Time

Summer heat can be both enjoyable and taxing on your lawn. High temperatures, scorching sun, and lack of water can take their toll on its roots; high foot traffic in your yard and backyard may also wreak havoc on its health.

Year-round care and maintenance must begin for a lawn that can easily withstand summer's heat. This involves fertilization, irrigation, and cutting the grass at appropriate intervals.

When it comes to mowing, it is essential not to cut more than one-third of a leaf in one cutting - this helps maintain cooler conditions for plants while protecting their roots from stress.

Mowing should also be avoided during periods of extreme heatwave. A heatwave is any period in which temperatures exceed what would typically be expected in your region at that time of year and lasts for weeks or months.

Mowing during a heatwave can put undue strain on grass, slowing its recovery. This could leave your lawn with patches where too much grass was cut off and encourage heat-tolerant weeds that thrive under those conditions.

If you must mow during a heatwave, ensure the lawn is dry from dew, rain, or irrigation. Wet grass blades can fold or bend over more easily while being cut over, increasing their risk of damage and making surviving more challenging during times of high temperature. Furthermore, moist grass loses moisture faster, making it more challenging to survive a heatwave.

If you must mow during a heatwave, try only mowing when necessary and reduce its frequency; this will minimize stress on the grass and help it thrive in the summer heat. Furthermore, it's best to forgo lawn chemicals or yard treatments during this period; rather, focus on aerating soil to retain more moisture and encourage deeper rooting. When possible, water only in the late afternoon - when temperatures peak.

Don't Mow at the Wrong Speed

When cutting grass, it is essential to remember the "1/3 Rule." Never cut more than 1/3 of its height at one time to keep your lawn cooler as less plant tissue is removed; this is especially important during hotter weather when grass plants may become more stressed.

Notably, the recommended height of grass cutting varies based on the type of lawn and season. Do your research before consulting a professional to establish the most suitable height to mow at.

Homeowners and lawn maintenance services often make the mistake of mowing too quickly during the summer season, often cutting too much plant tissue in one pass and creating stress on the grass, leading to bare spots or even death, which requires time, money, and effort for repair.

Finally, people must avoid walking or playing on their lawns during the day's peak heat. High traffic on grass can prevent airflow around blades - inhibiting their natural cooling mechanism - transpiration. To decrease this impact, consider moving picnic rugs and paddling pools into different parts of your yard and moving dog toys, goalposts, or other play equipment every few weeks to give the grass time to recover.

As well as avoiding these common errors, it's also essential that lawns receive extra water during the heat of summer to help them remain cool and prevent them from overheating. Aeration also plays a crucial role in soil drainage and root development - mulching grass clippings rather than bagging them can add nutrients directly into the lawn and slow moisture loss during this season of extreme heat.
