When summer arrives in Wisconsin, many homeowners focus on enjoying their yard—but July and August can be some of the most stressful months for your lawn.
Between heat, drought conditions, kids playing outside, and backyard gatherings, your grass can quickly show signs of wear. The good news? A healthy summer lawn doesn't require complicated treatments or constant watering. In fact, some of the most effective lawn care practices are surprisingly simple.
Here are the most important things homeowners can do to help their lawn survive—and thrive—during the hottest months of the year.
1. Water Deeply, Not Daily
One of the biggest mistakes homeowners make during the summer is watering a little bit every day.
While it may seem helpful, frequent shallow watering encourages grass roots to stay near the surface, making them more vulnerable to heat and drought. Instead, focus on deep, infrequent watering.
A good rule of thumb is to provide about one inch of water per week, including rainfall. Watering two to three times per week in longer sessions encourages roots to grow deeper into the soil, helping the lawn become more resilient during dry periods. Early morning watering is ideal because it minimizes evaporation and gives the grass time to dry before evening. ()
2. Raise Your Mower Height
If your lawn is struggling during the summer, your mower may be part of the problem.
Taller grass creates shade for the soil, helping it retain moisture and stay cooler. Longer grass blades also support deeper root growth, which improves drought tolerance.
During the hottest part of the summer, consider mowing at your mower's highest recommended setting. Avoid removing more than one-third of the grass blade during any single mowing. Cutting too much at once can stress the lawn and slow recovery. ()
3. Leave the Grass Clippings
Many homeowners bag their grass clippings without realizing they're removing valuable nutrients from the lawn.
Mulching your clippings returns organic matter and nutrients back to the soil naturally. These clippings break down quickly and can help support lawn health throughout the growing season.
As a bonus, you'll save time by skipping the extra cleanup. ()
4. Be Careful with Summer Fertilizer
More fertilizer doesn't always mean a healthier lawn.
Cool-season grasses common throughout Wisconsin—such as Kentucky bluegrass and fescue—often slow their growth during periods of intense heat. Heavy fertilization during these stressful conditions can sometimes create additional strain.
Many lawn care experts recommend focusing on proper watering and mowing practices during peak summer heat and saving major feeding applications for cooler portions of the growing season. If fertilizer is used, a lighter, slow-release approach is generally preferred. ()
5. Watch for Signs of Heat Stress
Your lawn will often tell you when it needs attention.
Some common signs of heat stress include:
- Footprints that remain visible after walking across the lawn
- Grass blades that appear wilted or folded
- Browning tips
- Thin or patchy areas developing in sunny spots
If you notice these symptoms, focus on proper watering and reduce unnecessary traffic on stressed areas until conditions improve. In many cases, lawns can recover once temperatures moderate and moisture levels return. ()
6. Remember: Brown Doesn't Always Mean Dead
This is one of the most important things homeowners should know.
During extended periods of heat and drought, many cool-season lawns enter a protective dormant state. While the lawn may appear brown, the grass is often simply conserving energy until more favorable conditions return.
With adequate moisture and cooler temperatures, many lawns will green back up naturally. ()
Protecting Your Home's Curb Appeal
A healthy lawn is one of the first things visitors notice when they arrive at your home. Whether you're planning to stay for years or considering a move in the future, maintaining your lawn during the summer months helps preserve your home's curb appeal and overall value.
Fortunately, the basics remain the same:
- Water deeply
- Mow high
- Avoid over-fertilizing
- Reduce stress during extreme heat
Sometimes the simplest lawn care practices produce the best results.
