The Weather Network – Here’s what warmer temperatures mean for your lawn
Monday, May 9th 2022, 1:15 pm – It’s OK to let your lawn go dormant during periods of extended heat.
Grass – it’s everywhere. You probably don’t think a lot about it, unless it’s on your property.
But here’s the thing: Growing and maintaining a lush lawn can be challenging anywhere in Canada – you can thank our weather for that.
In Canada, we have cool-season lawns, consisting of Kentucky bluegrass, perennial rye grass, fine fescues, and tall fescus. These types of grass do best if they’re planted when the temperature is between 15 and 21 degrees Celsius, and they’re suitable to grow up to about 28 degrees Celsius.
When the temperature climbs past that, you’ll have to help your lawn by adding extra water, but regular maintenance can give you some wiggle room.
“You should always mow it at a very high height of three to four inches, ideally so that it can maintain that food store protect its root and the crown of the plant, so it can grow actively without all of the extra stresses,” Kyle Tobin of Lawnsavers Plant Health Care Inc. told The Weather Network last year.
“And then you can get a couple of extra degrees out of the days.”

What happens when the temperature climbs past the 30-degree mark?
“You’re not going to grow healthy grass in 32 degrees Celsius or in anything above that,” Tobin said.
Just because your grass loses its lush green, doesn’t mean it’s dead and gone – it’s just dormant.
During periods of intense heat, Tobin recommended giving your lawn a deep watering once a week. It may not green up right away, but you’ll be protecting the roots.
“The brain stem of the plant, called the crown, will be maintaining hydration so that when it comes time it will quickly send off new leaf blades.”
