Lawn Stress Relief: How to Identify & Treat Heat-Stressed Grass in Idaho Falls

Written by Chase Coates | Jun 11, 2024

When the Idaho Falls summer hits its peak, your lawn feels the pressure just as much as you do. Our cool-season grasses thrive in spring and fall, but the high-desert heat can quickly push them into survival mode.

Heat stress happens when your turf loses moisture faster than it can take it up, leading to a lawn that looks flat, lifeless, and brown.

If you notice "ghost prints" that don't bounce back after you walk across the grass, your lawn is sending an urgent signal for relief.

The biggest challenge is knowing whether your grass is just dormant or actually dying. In Eastern Idaho, heat-stressed grass will often hunker down to conserve energy, but without the right intervention, that dormancy can turn permanent.


Helping your lawn survive the summer requires a strategic approach to mowing, watering, and timing your nutrients.

 

Lawn Heat Stress: What Is It?

Heat stress happens when lawns lose too much moisture due to hot, dry weather. Cool-season grasses, as we have here in Idaho, are especially susceptible to extreme summer heat. They prefer fall, thanks.

Not sure if your lawn is suffering drought stress? Watch for a few key signs:

Grass blade tips turn brown. They might also curl.

Brown patches form on your lawn. This is tricky, though, because other lawn problems, from bugs to lawn diseases, turn grass brown, too.

How do you identify lawn heat stress vs fungus or insects? Consult with a lawn care pro to confirm the cause and ensure you’re getting proper treatment, if necessary.

“Ghost prints” appear. This sounds spooky and cool but it’s not good. When you walk across your grass, it doesn’t bounce happily back up after your foot leaves the ground.

A drought-stressed lawn lies flat and lifeless.

How to Handle Lawn Heat Stress?

Be ready to come to the rescue:

  • Think ahead, before it gets too hot, and give your lawn the right fertilizer early in the season, to boost its health and heat tolerance. Hold off on fertilizing during the hottest part of summer. Your grass isn’t growing much now, so it can’t really take in the nutrients.
  • Give your lawn plenty of water as summer approaches, so it enters the season well hydrated and better able to withstand heat stress.
  • Don’t trample the poor grass. When your lawn is battling hot weather, give it a break and ease off on the foot traffic.
  • Mow tall. That extra length helps keep the crowns of the grass plant cool and shaded. Then it has a better chance at staying its healthy green self. Taller grass grows deeper roots, better able to reach moisture that's deeper in the soil.
  • Mow early in the morning before the heat of the day. (That's more pleasant for you, too!)
  • Keep that mower blade super sharp so it makes a clean, healthy cut. Dull mower blades shred the grass, and those ragged edges lose more moisture, making grass more susceptible to lawn drought stress.
  • Water early in the day, so more water reaches the roots and you lose less to evaporation. Shoot for about an inch a week.

Like everything in lawn care, it's better to be prepared for a problem than to react to it.

Putting these practices in place before warm weather arrives will give your lawn a head start on surviving stressful weather.

Oh, Man, What if It’s Dead?!

Brown grass can freak you out. Does it have lawn heat stress? Did it go dormant? Is it dead?

Cool-season grasses like the varieties here in Idaho love spring and fall, happily growing faster than you can mow them.

But when that 80-degree weather stresses them out, they can enter a summer dormancy period. The grass stops growing to conserve water and nutrients — it needs to chill out.

A dormant lawn is different than a dead lawn. When your lawn is dormant, it’s not actively growing. It looks dead, but deep down, the crown of the grass is still alive.

How to tell the difference?

Grab hold of a couple clumps of grass and tug. Does it pull right up, with no root system holding it in? It’s probably dead. But dormant grass in Idaho will still have a solid root system and resist your tug.

No worries. It’ll be back.
