Mowing is one of those classic summer jobs. However, taking the lawn mower out in a heatwave can actually damage your grass. So when is it too hot to mow? When the temperatures hit 90°F, lawn care experts warn homeowners not to cut their grass, as doing so places extreme stress on the lawn. Mowing when the temperatures reach dangerous levels can lead to heat stress, brown patches, or even kill the grass.
It is important to resist any urge to mow when temperatures reach such critical levels. You don't want to put lots of effort into lawn care over the rest of the year, only to undo all the hard work with risky mowing in summer.
