When summer temperatures rise, one of the most common questions we get at Northern Roots Lawn Care is, “Am I watering my lawn enough?” The truth is, proper watering can make all the difference in keeping your lawn green, healthy, and resilient during a Minnesota summer.
Here are the top lawn watering questions (and answers!) we hear from homeowners year after year:
Q: How Often Should I Water My Lawn? 
A: Most Minnesota lawns need about 1 to 1½ inches of water per week, including rainfall.
Instead of watering a little every day, it’s better to water deeply one or two times per week. Deep watering encourages roots to grow farther into the soil, helping your lawn withstand heat and dry conditions.
Q: What Is the Best Time of Day to Water My Lawn?
A: The best time to water your lawn is early in the morning, ideally between 5:00 a.m. and 9:00 a.m.
Morning watering gives the soil time to absorb moisture before the heat of the day causes evaporation. It also allows the grass blades to dry out, reducing the chance of lawn diseases that can develop when grass stays wet overnight.
Q: How Do I Know If My Lawn Is Getting Enough Water? 
A: Using a rain gauge is the easiest way to measure the amount of water your lawn is getting.
Place the rain gauge in your yard to measure both rainfall and sprinkler output. Once you’ve collected about 1 to 1½ inches of water for the week, you can hold off on watering until your lawn needs more. It’s an inexpensive way to prevent overwatering while making sure your grass gets exactly what it needs.
Q: How Long Should I Run My Sprinklers?
A: The answer depends on your sprinkler system, but the goal is always the same: apply 1 to 1½ inches of water each week.
Make sure your sprinklers are:
- Watering evenly across your lawn
- Not spraying sidewalks or driveways
- Adjusted as the season changes
A few small adjustments can improve efficiency and help you avoid wasting water.
Q: How Can I Tell If My Lawn Needs Water? 
A: Your lawn will usually let you know!
Watch for signs like:
- Grass turning a dull blue-green color
- Footprints remaining visible after walking across the lawn
- Grass blades beginning to curl or wilt
If you notice these signs, it’s time for a deep watering before your lawn becomes stressed.
Q: How Can I Tell If I’m Overwatering My Lawn? 
While underwatering gets a lot of attention during the summer, overwatering can be just as harmful. Too much water can actually weaken your lawn’s root system, encourage fungal diseases, and create the perfect environment for weeds to thrive.
Common signs of an overwatered lawn include:
- Mushy or soggy areas that never seem to dry out
- Yellowing grass despite frequent watering
- Mushrooms growing in the lawn
- Excessive weed growth
- Water pooling on the surface after your sprinklers run
If you notice any of these signs, try cutting back on your watering schedule and make sure you’re using your rain gauge and your lawn is only receiving the 1 to 1½ inches of water per week we’ve already discussed, including rainfall.
