A mowing height between 2.5 to 3 inches is best for most of the season, except during summer stresses when the lawn mowing height should be raised one-half inch to mow at 3 to 3.5 inches. Raising the mowing height provides more insulation from summer heat and reduces water loss from your soil.
Typical warm-season grass height range: 1-3 inches. During periods of peak growth, expect to mow the lawn once every 5-7 days. Conversely, during times of slowest growth, you'll mow less, if at all.
One of the most common questions we hear is, “How often should you mow your lawn in the summer?” Over the summer you'll generally mow your lawn every 4 to 6 days.
So, what's the best time of day to mow a lawn in hot weather? Plan to mow your lawn during the evening hours, after the heat of the day has passed. The temperature should be between 40°F and 80°F.
Once temperatures reach 77 degrees, it becomes too hot for root growth, and root growth ceases. When temperatures reach 90 degrees, it becomes too hot for shoot growth and the grasses stop growing and begin to fall dormant, with the surface grass turning a brown hue.
Watering on a hot summer afternoon is a horrible idea. The liquid will evaporate too quickly and may not reach your grass's roots, so heat and irrigation shouldn't go together. Instead, the best time to water grass during summer is in the morning. The ideal time for morning watering is before 9 AM.
During really hot weather, water your vegetables at least two to three times a week. Watering the garden deeply is critical. The water must go down, down, down to encourage deep roots and get away from the hot soil surface.

Longer grass will keep the roots cooler by providing more shade. Another way to think about this is to avoid cutting more than a third of the grass off the top. This is a good rule to follow throughout most of the year, but especially when it's hot.
Check the soil: If the it looks muddy or feels soft, it's usually better to wait. Ideally, you should wait until the grass is dry enough so that you can walk through the lawn and not have wet shoes.
Mowing actually helps make your grass grow thicker because the tip of each blade contains hormones that suppress horizontal growth. When you cut the lawn, you remove these tips allowing the grass to spread and grow thicker near the roots.
Mowing every two weeks — instead of weekly — and not dousing grass with chemical herbicides and fertilizers, helps the environment and supports the health of bees, which are among the world's most important pollinators.
For this reason, some people prefer to mow at 3 or 3.5 inches. For the healthiest and most sustainable approach, Michigan State University Extension says 3.5 to 4 inches is most desirable. Lawns mowed at 3.5 or 4 inches out-compete weeds, tolerate grubs and look just as good as lawns mowed at 2.5 inches.
The mowing height range for most grasses is between 1.5 and 3 inches. In general, for most lawns 2 to 2.5 inches is optimum because if you are mowing at 3 inches, your lawn may grow to 5 or 6 inches before you mow it again. Here are some problems associated with letting your grass grow too long: Lawn thinning.
How Scalping Affects Grass. Grass is able to survive thanks to photosynthesis, which is the process of taking in sunlight and using it as energy. Cutting too much of the leaf blade limits the lawn's ability to store this energy, restricting its nutrient supply and ultimately choking the grass.
It is often recommended that you water your lawn early in the morning, as early as 4 am and no later than 10 am. During extreme heat, watering should be done no later than 7 am.
Even if the grass is green and growing in summer, it's helpful to mow high. Taller blades not only shade the soil, but they mean more chlorophyll is available to help fuel root growth. Cool-season grasses are best cut to a height of about 3 inches.
In high stress periods, light fertilizer applications will keep your lawn healthy or assist in recovery. If the drought is severe enough, let it go dormant. In conditions when the heat is just too much for your grass to overcome, it will essentially shut down until cool, moist weather returns.
Allow all grasses to grow taller in summer and during drought. Mow warm-season turf shorter in spring to remove dead grass blades. Mow cool-season grasses shorter for the final fall mowing in snow prone regions to help prevent snow mold.
Excessively hot weather and exposure to full sun throughout the day causes a lawn to dry out and turn yellow in warmer seasons.
In general during hot summer months, you should be watering your lawn up to three times per week if there wasn't any recent rainfall. As a general rule of thumb, watering up to one inch deep each time you water your lawn is ideal.
In times of extreme heat, it is vital to water your lawn for about 30 to 45 minutes daily. Once the temperatures drop below ninety, you can cut back to watering three to four times a week, until that blissful thunderstorm comes and quenches your lawn's thirst!
When working in the heat, drink 1 cup (8 ounces) of water every 15–20 minutes. This translates to ¾–1 quart (24–32 ounces) per hour. Drinking at shorter intervals is more effective than drinking large amounts infrequently. Do not drink more than 48 oz (1½ quarts) per hour!
If you forget or are too busy to water your plants on some summer mornings, you can water them at night. However, this should not be your ordinary watering time. Morning is the proper time for watering plants, though you should keep in mind that not all plants need daily watering.
