Grass is generally classified as either being cool or warm season.

Cool-season grasses adapt well to cold seasons and will survive winter in most cases.

On the other hand, warm-season grasses thrive in the summer and spring months and often become dormant in the winter.

If you take care of your lawn, most grass varieties do not die in the winter.

However, under harsh winter conditions, the grass turns brown and enters a dormant state. Once the temperatures start rising in spring, the grass resumes its growth.

When the temperatures dip below 40 degrees F, the grass does not grow.

It becomes dormant, and you will not need to mow during the winter.

Watering grass in the winter

If you live in a region that hardly experiences frost, for instance, in the state of Florida, your lawn will still go into some dormancy.

The grass may grow slowly and will not look as beautiful as it does in spring or summer.

However, if the winter is freezing, the roots of the grass may get damaged. When this occurs, the entire grass affected will eventually die off.

You will notice some patches on your lawn even when spring comes. Therefore, you may need to plant more grass in those affected places to maintain a consistent lawn.

Homeowners need to ensure that the lawn is healthy before the winter hits. Mowing your lawn regularly is among the best practices for providing a good lawn.

Key Takeaway – Watering and fertilizing the grass appropriately prepares the grass for winter. If the grass is vibrant with a robust root system, it will survive the cold nights of winter.

How Winter Affects Different Grass Varieties

Cool-season Grass

Also, these species do well in early spring and remain green under cold weather conditions. However, these varieties may become dormant when there is intense humidity and heat.

Cold-season varieties such as tall fescue, red fescue, ryegrass, and Kentucky bluegrass often become dormant in summer and thrive in cold weather.

Therefore, cool-season types will survive freezing temperatures.

However, you should avoid stepping on the lawn since the stem of the grass break easily in frosty conditions and may affect the roots. 

Warm-season Grass

Conversely, warm-season grass varieties are affected more by cold winter weather.

These species often turn brown and hardly grow in the winter period.

These varieties include:

At most times of the year, warm-season grasses remain healthy as long as the temperatures do not dip below 40 degrees F.

Do not be concerned when your lawn turns brown and your grass stops growing. The roots are still alive, and the grass will grow back when spring comes.

However, if you notice that your lawn has patches when spring arrives, it probably means that the roots failed to survive the winter.

Therefore, it is crucial to understand the different grass varieties and the temperature range in which they can survive.

Selecting an appropriate grass species will ensure your lawn remains healthy throughout the year.

It may also look dry and dead. However, just because your yard turns brown does not mean the grass is dead.

In Most Cases – Your lawn has warm-season grass, which becomes dormant during winter. The grass will revive to its green color when the surroundings become warmer during spring.

However, some of the grass roots may die off after a harsh winter, and your yard may not look as nice due to the patches.

In this case, you can try over-seeding during the spring.

Some homeowners mix cool and warm season grass varieties in their yards to ensure a green lawn throughout the year.

However, it is best to plant a species suitable for your climate and location.
