‍Grasses will die if the temperature doesn’t reach above freezing level. This is the condition that most grasses need to survive. These grasses have a dull period during the wintertime. This can cause many issues for the homeowner, unaware that the grass is dead.

There are a few ways to get around the problem of post-frost grass. One of which is to mow the grass once the temperature has made it to the freezing level.

When your lawn is covered in frost, you can mow your grass. This can be tricky if you haven’t done it before.

We’ll walk you through step-by-step instructions on how to mow after frost and keep your lawn looking great all summer long.

Can You Mow Grass after Frost?

You can mow your lawn after frost as long as you take a few precautions. Frost damages grass by destroying the blades’ tips, which means you can cut frosted grass, but you won’t get outstanding results. You may get some brown or dead spots on the lawn, especially if the frost is intense.

It’s usually fine to mow after a light frost, but after a hard frost, you’ll get better results if you wait until the lawn has grown new, unfrosted blades of grass.

How to Mow Grass after Frost? – Step-by-Step Guide

There are a few things you can do to keep your lawn looking its best after a cold front. Here are some tips to help you succeed:

1. Set the mower blade high

Before you start mowing, make sure the blade is set high. This will ensure that your lawn gets cut evenly and will also help prevent clippings from flying around when you’re cutting them.

Set the height at 1 inch (2.5 cm). If you have more than one blade on your mower, ensure they are all set at this same height. 

Mow in the direction of how grass grows don’t cut off more than one-third of a blade at any time unless otherwise instructed by your local landscaper. When mowing wet grasses, use extra care to avoid damaging roots or plants underneath.

2. Rake up Debris

Rake up leaves and other debris Vacuum up leaves, grass clippings, and other debris. Apply a pre-emergent herbicide.

Pre-emergent herbicides are used to control crabgrass. These herbicides kill the seedlings as they emerge from the soil, preventing new growth and allowing you to cut them down before they grow any taller.

There are several types of pre-emergent herbicides:

  • Roundup Ready® Pro soybean & wheat granules (glyphosate) can be applied at 5-8 lbs per 1000 sq ft.
  • Roundup Universal Triazicide + 2-4 oz/gallon of water (triazine) can be applied at 1 quart plus 3 gallons per 1000 sq ft.
  • Glyphosate plus Dicamba paraquat + 2 quarts per 1000 sq ft.

3. Aerate Your Lawn

Use a core aerator to remove plugs of soil and plugs of sod, then use a dethatcher to remove thatch. Compact the soil, it will be soft enough for mowing and easy on your lawnmower’s blades so you don’t have to pull out a rake.

This step also helps prevent weeds from sprouting up in the springtime.

If your yard isn’t compacted correctly yet, use a hand weeder or leaf blower with caution often, leaving behind too many clumps can cause damage down the road if not removed soon enough.

4. Dethatch your Lawn

Dethatching is removing thatch, which can harbour weeds and other pathogens. Thatch is also known as “green matter” or “organic matter” because it contains grass roots, stems, and leaves.

Most mowers will have dethatchers on their blades that remove clippings when pulled across the lawn. You can also use a rake to remove clumps of sod or turf from around trees or shrubs.

This works exceptionally well if you’re trying to keep your grass neat while dethatching it simultaneously.

5. Seed Bare Patches of Grass Where Needed

If you have bare spots on your lawn, seed them before winter. The best way to do this is by planting in late fall or early spring. This will give the grass time to grow and fill out before winter, making it easier for you to mow next spring. 

You’ll also have to ensure that the soil is not frozen before you plant any seeds. Otherwise, they may not germinate properly and die off before sprouting up again once temperatures warm up later on.

Treating Frost Damaged Grass

Frost damage to grass can be a real problem. If your lawn has been damaged by frost, the best thing you can do is try to let it heal on its own. But if you’re thinking: “I want my grass back!” So here are some tips for treating frost-damaged grass:

  • Be gentle with your grass:

While doing all this, please don’t walk on it or let your pet run on it. Also, don’t mow, fertilize, or spray anything on the grass. If you need to water the grass and can’t wait until springtime, use a small amount of water first and then leave the rest of the hose off so that no more moisture gets added to your lawn.

If your lawn is damaged by frost damage and needs a little extra help getting back into shape again and if there’s any chance that these steps might help, consider adding some salt at this time as well.

  • Fill in the gaps on your lawn:

Now you have to fill in the gaps on your lawn. You can use grass seed, plugs, or a combination of both. Water regularly with warm water. The first thing that you should do is water your lawn with warm water. 

This will help the grass recover from the frost damage and prevent it from drying out. You can use a garden hose or even a sprinkler, but ensure that you don’t pour too much water on your lawn because this can cause damage to other plants in your yard.

  • Aerate the lawn in spring and summer:

This will help to remove plugs of soil and improve the health of the roots, while also improving water and nutrient uptake by the grass. You can use a lawn aerator or even a hand-held cultivator with an attachment to make this happen, but be sure to follow safe operating guidelines.

This should be done in spring or summer when your lawn is at its healthiest point. If you wait until it’s too late, then it could lead to slower growth rates because there isn’t enough energy being produced by healthy root systems.

If the frost heavily damages your Lawn, don’t try to mow it. You’ll just be scalping the blades and making the situation worse.

What Temperature is too Cold to Mow the Grass?

You will have to check the temperature. If there’s a frost forecast, it’s probably too cold to mow the grass. You also don’t have to mow when the soil is too wet because this will damage your mower.

As a general rule, wait until the temperature is around 50 degrees Fahrenheit before you start mowing. You’ll also have to wait until the soil is dry enough to mow without damaging your lawn mower.

When to Cut Your Grass if Frost is Expected?

If the forecast calls for frost, the best thing you can do is wait to cut your grass until the temperature rises and the frost passes.

Even if the forecast only predicts a light frost, you may want to wait until the temperature rises again.

Cutting grass during a light frost is risky, as the blades may freeze in the lawn mower. Cutting grass during a heavy frost can be disastrous, as the blades may freeze to the ground.

Can You Fertilize the Lawn after Frost?

You can fertilize your lawn after frost, but you’ll need to follow a few extra steps. If you fertilize before the frost, the fertilizer will run off with the water.

But if you fertilize after the frost, the fertilizer will be trapped by the frost and will not run off as easily. You’ll also need to avoid using nitrogen-rich fertilizer after a frost because this can actually encourage the grass to regrow frozen blades. read more

Final Takeaways:

With the right gear, you can mow your lawn right after a frost! However, it’s important to know that frost activity typically lasts for one to two weeks. That means that if you want your lawn to look its best, your best bet is to mow your lawn during the weekdays. If you mow your lawns on the weekends, you can still get the benefits of a good mowing job.

In addition to helping retain rainwater in the lawn, mulching helps reduce weeds and also keeps the grass cool and moist throughout the summer months. The natural layer of mulch will also help prevent nutrient loss.

However, mowing your lawn after frost is not ideal and will likely cause some damage to the grass, if you will wait until the temperatures rise and the frost is gone before mowing your lawn. This will help protect your grass from frost and give it time to grow and get ready for spring.
