How Often Should You Water Your Lawn During Summer?
A lush, green lawn is one of the best parts of summer, but keeping it healthy during Michigan’s hottest months takes more than just turning on the sprinkler.
One of the most common questions homeowners ask is:
“How often should I water my lawn during summer?”
The answer isn’t as simple as watering every day. In fact, watering too often can be just as harmful as not watering enough. Understanding when, how much, and how often to water your lawn can make all the difference in maintaining healthy, resilient grass throughout the season.
How Much Water Does Your Lawn Need?
Most established Michigan lawns need about 1 to 1½ inches of water per week, including rainfall.
Rather than watering a little every day, it’s better to water deeply and less frequently. Deep watering encourages grass roots to grow farther into the soil, making your lawn more drought-tolerant and better able to withstand summer heat.
How Often Should You Water?
For most lawns, watering two to three times per week is ideal.
Each watering session should provide enough moisture to soak the soil 6 to 8 inches deep. This helps develop stronger root systems instead of shallow roots that dry out quickly.
The exact schedule will vary depending on:
- Recent rainfall
- Soil type
- Grass variety
- Sun exposure
- Temperature and humidity
If your lawn receives an inch or more of rain during the week, you may not need to irrigate at all.
The Best Time to Water Your Lawn
Timing is just as important as frequency.
The best time to water is early in the morning, between 5:00 a.m. and 9:00 a.m.
Morning watering allows moisture to soak into the soil before the day’s heat causes excessive evaporation. It also gives grass blades time to dry, reducing the risk of fungal diseases.
Try to avoid watering:
- During the hottest part of the afternoon, when much of the water evaporates.
- Late in the evening, when prolonged moisture can encourage disease.
Signs Your Lawn Needs Water
Your lawn will often tell you when it’s thirsty.
Watch for:
- Grass blades folding or curling
- A dull blue-gray color
- Footprints remaining visible after walking across the lawn
- Dry, brittle grass
These are signs it’s time for a deep watering.
Signs You’re Watering Too Much
More water isn’t always better.
Overwatering can lead to:
- Shallow root systems
- Increased weed growth
- Lawn diseases
- Fungal problems
- Wasted water
If your lawn feels consistently soggy or mushrooms begin appearing, you may be watering too frequently.
Tips to Help Your Lawn Handle Summer Heat
Proper watering works best when combined with good lawn care practices.
Mow High
Keep your mower set between 3 and 4 inches during the summer. Taller grass shades the soil, reduces evaporation, and encourages deeper roots.
Leave Grass Clippings
Grass clippings return valuable nutrients to the soil while helping retain moisture.
Apply Mulch Around Landscaping
Mulch helps flower beds, shrubs, and trees conserve moisture while keeping roots cooler during hot weather.
Keep Your Fertilization Program on Schedule
A properly fertilized lawn develops stronger roots and is better equipped to handle summer stress. Professional slow-release fertilizer programs provide steady nutrients without promoting excessive growth during the hottest months.
Should You Let Your Lawn Go Dormant?
During extended periods of drought, cool-season grasses common in Michigan may naturally go dormant.
Dormant grass turns brown but is often still alive. If watering restrictions are in place or you’re comfortable allowing dormancy, your lawn can typically survive several weeks of dry conditions.
However, providing about ½ inch of water every two to three weeks can help keep the crown of the grass alive until cooler weather returns.
