What Month Does Grass Stop Growing: Seasonal Lawn Maintenance Tips
What Month Does Grass Stop Growing?
Grass stops growing in the fall or winter when temperatures drop below 40-50°F (4-10°C) and the amount of daylight decreases.
The specific time when grass stops growing depends on factors such as the species of grass, climate, soil conditions, and length of daylight hours.
Warm-season grasses go dormant and turn brown in the winter, while cool-season grasses may continue to grow in warmer regions during the winter.
Maintenance practices, such as watering, mowing, and fertilizing, can affect grass growth.
It is recommended to stop mowing the grass a few weeks before the first frost to allow it to grow and build up reserves.
Keeping the grass at a height of around 2.5-3 inches during the fall can help protect the roots from cold weather.

Did You Know?
1. Contrary to popular belief, grass does not actually stop growing in any specific month. It simply slows down its growth during the colder months of the year.
2. The growth of grass is significantly influenced by the amount of available sunlight. As the days get shorter, which typically occurs in the autumn months, grass growth gradually diminishes.
3. While overall grass growth decreases in winter, certain types of grasses such as Kentucky bluegrass and perennial ryegrass actually continue to grow when temperatures remain above freezing.
4. Grass growth can be influenced by soil temperature rather than air temperature. This means that even on cooler days, if the soil is warm enough, grass can still continue to grow.
5. The specific type of grass found in an area can determine when it appears to stop growing. Some cool-season grasses may appear to cease growth in winter, while warm-season grasses might enter dormancy during hotter months.
Factors That Influence Grass Growth
Grass growth and cessation are influenced by various factors, including the species of grass, climate, soil conditions, and the length of daylight hours.
Different types of grass have different temperature thresholds for growth. In general, grass stops growing when temperatures drop below 40-50°F (4-10°C). This drop in temperature combined with a decrease in daylight hours during the fall and winter months signals the grass to enter a period of dormancy.
The specific time when grass stops growing can also be affected by the local climate and soil conditions.
- Warmer regions may experience extended periods of growth for cool-season grasses during the winter months.
- In contrast, colder regions with freezing temperatures and longer winters may see grass growth completely halting for both warm-season and cool-season grasses.
Note: The growth and cessation of grass can differ based on climatic and soil factors.
Dormancy Of Warm-Season And Cool-Season Grasses
Warm-season grasses, such as Bermuda grass or St. Augustine grass, are known to go dormant and turn brown during the winter months. This is a normal and natural response to the colder temperatures and shorter daylight hours. In the absence of active growth, warm-season grasses conserve energy and build up reserves to survive until the conditions become favorable for growth again in the spring.
Cool-season grasses, including Kentucky bluegrass and tall fescue, have a higher tolerance for colder temperatures and can continue growing in milder and warmer regions during the winter. However, their growth rate may significantly slow down compared to the active growth phase in the spring and fall. It is essential to consider the specific grass species in a given area to determine how grass growth will be affected by the seasonal changes.
Importance Of Maintenance Practices In Grass Growth
Maintenance practices play a critical role in grass growth and overall lawn health. Proper watering, mowing, and fertilizing techniques can significantly impact the growth and resilience of grass.
Proper watering throughout the year is essential to ensure that the grass has enough moisture, especially during dry periods. Adequate moisture levels promote healthy growth and help the grass withstand temperature fluctuations.
Mowing practices should be adjusted as grass growth slows down in the fall. It is crucial to stop mowing a few weeks before the first frost to allow the grass to grow and store reserves. Longer grass blades during this period can provide additional insulation and protection for the grass roots against cold weather. Maintaining a recommended height of around 2.5-3 inches during the fall can help achieve this balance.
Fertilization is another critical aspect of maintenance that impacts grass growth. Applying a winterizing fertilizer in the fall can provide essential nutrients to the grass, ensuring it remains healthy and well-nourished during the dormant period. This promotes stronger regrowth in the spring and prepares the grass for the upcoming growing season.
- Proper watering throughout the year, especially during dry periods, promotes healthy growth.
- Adjust mowing practices in the fall, stopping a few weeks before the first frost.
- Longer grass blades during fall provide insulation and protection for roots against cold weather.
- Maintain a recommended height of around 2.5-3 inches during the fall.
- Apply winterizing fertilizer in the fall to provide essential nutrients for healthy grass growth.
Timing And Height Of Grass Mowing
Mowing the grass at the right time and height is crucial for maintaining a healthy lawn.
The timing of the last mowing session before winter will largely depend on the region and the specific grass species present. As mentioned earlier, it is generally recommended to stop mowing a few weeks before the first frost. This allows the grass to grow and build up reserves, making it more resilient during the dormant period.
The height at which you mow the grass during the fall is also important. Keeping the grass at a slightly longer height of around 2.5-3 inches provides better protection for the roots against cold temperatures.
Longer grass blades also increase the surface area for photosynthesis, allowing the grass to produce and store more energy before entering dormancy. A well-maintained height will ensure the grass remains healthy and ready for regrowth in the spring.
- Mow the grass a few weeks before the first frost
- Keep the grass at a height of 2.5-3 inches
- Longer grass provides better root protection and more energy production
Tips For Efficient Grass Mowing
To mow the grass efficiently and promote healthy growth, it is essential to follow a few tips and best practices.
-
Ensure the mower is in good working condition. Dull blades can damage the grass and create an uneven appearance. Therefore, it is crucial to sharpen the mower blades regularly.
-
Clear the lawn of any debris or objects that could hinder the mowing process or damage the mower. This includes sticks, stones, and toys.
-
Mow in straight lines or use a criss-cross pattern to create a more even and aesthetically pleasing result.
-
Avoid mowing the grass when it is wet or overly hot as this can stress the grass and impact its growth. Choose to mow when the grass is dry and the temperature is moderate.
-
Remember to take breaks during mowing and stay hydrated, especially during warmer weather.
-
After mowing, clean up the mower and other equipment to prevent the spread of diseases or pests.
By following these tips and best practices, you can ensure efficient mowing and contribute to the overall health and growth of your lawn.

Frequently Asked Questions
What months does grass grow the most?
Grass growth thrives the most during the spring months, specifically from March to May. This period corresponds to temperatures around 50°F, which is the perfect climate for grass to flourish. Once the temperature surpasses this threshold, additional warmth does not significantly impact grass growth, making the spring months the prime time for the lushest lawns.
What is the lifespan of a grass?
The lifespan of grass varies depending on the type and conditions it is grown in. Some grass species may have a shorter lifespan, lasting only a few years, while others can persist for several decades. Factors such as climate, soil quality, maintenance practices, and disease or pest susceptibility can influence the lifespan of grass. With proper care and regular maintenance, it is possible to extend the life of your grass and enjoy a lush and vibrant lawn for an extended period of time.
Do grass plants survive in winter?
During the winter months, grass plants face challenges in their survival. As temperatures drop, these plants are unable to access chlorophyll for nourishment, causing their growth to halt. However, grass has a remarkable ability to adapt and enters a dormant state, much like the hibernation of other animals. This dormancy allows the grass to conserve energy and withstand harsh winter conditions, ultimately ensuring its survival until warmer days arrive.
What happens to grass if you don’t cut it?
If you don’t cut the grass, it will start to grow taller, and weeds and woody shrubs will begin to sprout among it. The lack of regular maintenance will result in an unkempt yard filled with an overgrowth of plants. Additionally, the longer grass provides a perfect habitat for insects, leading to an abundance of pests in your living space. It is important to regularly mow the grass to maintain a neat and pest-free environment.
