Avoid walking on frosted grass.

Don't look now folks, but winter is right around the corner. That means the holidays are near, the air is getting colder, and frost is starting to appear on our lawns. It's the circle of life in the Northern Hemisphere! 

Depending on where you live in Canada, you've probably started to notice some silver frost blanketing your grass and gardens in the early morning, or even inches of snow and ice piling up on your properties. 

While it may be pleasing to the eye, frost can actually be a real problem for your lawn if the proper precautions are not taken. 

Here are some tips for avoiding frost damage on your lawn.

what is frost?

While many theories exist about how frost damages living tissue, the most common belief is that ice crystals damage and kill plant cells when they are forced into the leaf by the weight of a foot or by other means of traffic across a lawn.

For frost to properly form on grass, many people believe that the temperature must fall to 32°F. However, frost can occur in low lying shaded areas even when the official temperature is above 38°F, so you need to be careful depending on where you live in Canada.

Even if it's not freezing cold outside, frost can still affect your lawn. 


Walking over a lawn that is frost covered can cause significant and unsightly damage to the turf. Damage first appears as a blackening of the leaves, which gradually turns to a brown or tan colour. 

Don’t let this happen to your turf, folks. If and when it does get cold enough for frost, be sure to stay off of your frosted grass until the sun melts the frost away. 

Stay off your frosted grass until the sun melts it away.


Testing your grass after the temperature drops is a foolproof way of ensuring that no accidental frost damage occurs.

A quick test to determine whether it is safe to walk on the grass is to simply take your hand and wipe it parallel along the surface (tips) of the turf.  If your hand stays dry throughout the duration of the test, it is still too soon to walk on the turf.  If your hand is wet, then the frost has started to melt and it is safe to walk on.

Test your grass to make sure it is safe to walk on.
