By this point in the year, you have prepared your lawn for winter and may have already experienced the first frost. Your lawn service has been busy getting your lawn ready for winter and has likely come and gone for the last time before spring. If you care for your lawn yourself, you have already most likely already seeded your lawn and mowed for the last time this season. You know the first frost is the sign winter is coming. What exactly does that mean for your lawn? Why is that specific event so very important to keeping your lawn beautiful?

What is Frost?

Frost is much less menacing than it sounds. Frost is simply condensed water that has frozen overnight. It is not snow, nor is it not ice. Frost on your grass is caused by water that has condensed overnight on your turf grass when the temperature sank below 32 degrees. Because of the outside temperature, it formed frost. Had the temperature stayed above 32 degrees, it would have been dew. The colder nighttime temperatures that accompany the coming of winter cause morning dew to turn into frost.

Frost on the Lawn

Contrary to popular belief, the advent of frost – even the first frost – does not mean that the time to take care of your lawn is over. What it does mean is that the grass in your lawn will stop growing over the next few weeks. Once frost becomes a regular occurrence on your lawn, the growing process slows or stops completely because the grass is getting less nutrients.

There are some tips that will be helpful for your lawn care during this transitional time. First, as long as the lawn is green, it is still growing and alive. Therefore, continue maintaining it until it turns brown. Another key point is that the very best time to lay new seed is right after the first frost. This will allow the seeds to become nourished during the winter months.

Finally, the only way that frost can actually damage your lawn is from when an outside object comes into contact with the blades of grass while they are frosted. Frost makes blades of grass brittle. Until the frost dissipates, the grass blades are as fragile as glass. If you step on the grass while it is covered in frost, it will break the blades, killing it before the winter weather even sets in. This creates surface damage that will need to be fixed once spring comes and your grass begins to grow again.

As you can see, the first frost does not mean it is time to cease lawn care entirely for the winter. It simply is a signal that winter is coming. As long as you maintain your lawn until it stops growing for the winter, your spring lawn will be beautiful and summer-ready almost immediately.
