The Best Ways To Treat And Prepare Your Lawn Before The Winter

Lush emerald-green lawns don’t magically appear in the summer out of nowhere. This scenario is often the final result of months of care and maintenance that started the year before. Late fall is a crucial time for a lawn because you need to winterize it properly before the bitter cold arrives to keep it looking its best the following spring.

To prepare your lawn for the winter, promptly pick up leaves and debris to reduce the risk of mold. Adjust the height of your mower and decide when to stop mowing altogether. Change the watering schedule, and water deeply before the first frigid temperatures arrive. Add new seed as needed, and aerate compact soil to promote new growth. Apply winter fertilizer, and find ways to reduce foot traffic on the grass.

If you’ve ever wondered why your neighbor's lawn looks better than yours, you might be surprised to learn the secret is often winterizing. How you prepare your lawn for a cold, dormant winter can greatly affect how quickly and beautifully it grows when the season changes. To help your lawn survive a harsh winter and flourish in the spring, read the helpful tips below.

Factors To Consider Before Preparing A Lawn For The Winter

1. Climate And Winter Temperatures

Before you make a specific winterizing plan for your lawn, consider several factors, including the climate. Preparing a lawn in subtropical regions that rarely dip below freezing will vary significantly from areas covered in snow for months. Familiarize yourself with the area's average temperature, sunlight, rainfall, and how these factors impact your lawn. Some grass types go dormant for nearly six months, while others don’t, and you may need to mow them throughout the winter.

2. The Type Of Grass

More than 10,000 grass types exist and no two are the same. Each type has different needs, and has its own unique reaction to cold weather. You need to know your grass type to winterize it properly. This helps you buy the right seed and fertilizer and may even dictate how short it can be cut for the final time you mow it.

3. Soil Type And Composition

Soil type and composition in the fall can have major impact on how it's winterized. Each soil type holds moisture differently, which means you might need to adjust watering. Some soil types, like clay, are more prone to compaction. If you notice drainage issues or other red flags of compacted earth, thoroughly aerate your lawn well before the first frost arrives.

4. Winter Foot Traffic And Environmental Factors

Walking on grass once won’t kill it, but repeatedly stepping on it when it’s frozen can seriously damage your entire lawn. Consider the amount of foot traffic your lawn gets in the warm months and in the winter. The more abuse it goes through during the year, the more love and attention it needs each fall and spring.

10 Ways To Treat And Prepare Your Lawn Before Winter

1. Change Mower Height

One of the first changes to make is how short to cut the grass. Nearly all lawn mowers have adjustable blade heights. In the summer, when the grass grows quickly, you probably like cutting it short to reduce how often you need to mow. As temperatures cool, grass grows more slowly and becomes vulnerable. You should still cut it regularly, but not too short. When you cut grass too short in late fall, it becomes more susceptible to pests and may have a harder time bouncing back in the spring.

2. Rake And Remove Debris

Autumn is famous for its foliage, but once the colorful leaves die, they land on your lawn along with twigs and other organic debris. Do your best to keep your yard clean and clear of leaves and debris once fall arrives. This natural debris not only makes it harder to mow your lawn, but also makes the grass more susceptible to fungus and other mold growth. This is especially true when debris sits for long periods, including throughout the winter.

3. Aerate Compacted Areas

You should typically aerate your lawn once a year. In some cases, especially if you live somewhere with easily compacted soil, you might need to do it twice. Fall is a great time, as the key is to pick a time of year when it’s not too hot but the grass is still actively growing. Aerating in the fall stimulates fresh growth, leaving your lawn looking great and refreshed heading into winter.

4. Know When To Stop Mowing

A good way to protect your lawn in the winter is to know when to stop mowing. All grass types have temperature thresholds, and they typically stop growing once it gets too cold. You might want to start measuring the grass as fall progresses. If it hasn't grown much in more than 10 days, you are likely ready to mow it for the final time. 

5. Water Mindfully

As cold weather approaches, shift your watering schedule. Too much can waterlog your lawn, which can damage the roots and increase the risk of fungus. Still, as long as the grass is growing, it needs water, but reduce the quantity and frequency. Before the first cold snap arrives, give your grass one last thorough soak.

6. Add Seed As Needed

If you notice thin or dead patches, add plenty of new seeds to these areas in early fall. Give the seeds plenty of time to grow and the grass to thicken. This will give you a more uniform lawn in the spring.

7. Turn Off And Protect Sprinkler System

If you live in a climate with very cold winters, you need to winterize the lawn and your irrigation system. If you have a built-in sprinkler system, prepare it for freezing temperatures to prevent serious damage. Shut off the main water valve that connects it to your water supply. Blow all the water out of the system using compressed air or another method. Cover and protect the sprinklers to prevent weather damage.

8. Reduce Foot Traffic

Foot traffic can seriously damage a lawn in the winter, especially in an area that gets a lot of frozen precipitation. Whenever possible, limit foot traffic on your lawn, especially in vulnerable sections. Add temporary fencing, keep walkways clear, and make your patio and deck an enjoyable place to spend time outside.

9. The Right Winter Fertilizer

Most people associate fertilizer with the spring and summer, seasons when you want to add energy to plants that are already growing. While these are important seasonal gardening activities, in many cases, you should also add a winterizing fertilizer at the end of fall . These fertilizers are high in nitrogen and potassium and release slowly into the soil to help the grass come back strong in the spring. Choose the right product for your grass type and climate.

10. Preventative Weed Control

The best way to reduce weeds in your lawn is to prevent them from showing up in the first place. Using weed killer in late fall can help you have a pristine lawn in spring. Choose the right type of weed killer for cool weather and fall, and the right one for your grass. This can make it easier to deal with weeds once the grass starts growing quickly.

Summing Up Ways To Prepare Your Lawn For The Winter

If you want your lawn to look better, prepare it for the winter. Taking a few simple steps in the fall can help ensure it looks great once the ground thaws. Remove leaves and debris to prevent mold and disease, and know when to stop mowing and watering.

Winterize your sprinkler system, aerate the soil, and add new seed as needed. Find ways to reduce foot traffic on your lawn in the winter, use preventative weed control, and add the best winterizing fertilizer for your climate and grass type.
