Mow your St. Augustine grass once a week during the growing season for a lush, healthy lawn. In warmer months, you might need to mow more frequently, especially if the grass is growing rapidly, while in cooler periods, less frequent mowing can suffice. Keeping your grass at the right height encourages healthy growth and prevents pests.
For most homeowners, mowing St. Augustine grass once a week is ideal to maintain its vibrant appearance and health. This routine helps prevent the grass from becoming too tall or uneven. During peak growth periods in spring and summer, you may need to mow more often, but during cooler months, cutting every two weeks is usually enough. Proper mowing frequency ensures your lawn stays dense, green, and disease-resistant, making it a inviting space for outdoor fun and relaxation.
Taking care of St. Augustine grass requires understanding its growth patterns. This grass type thrives in warm climates and grows quickly in the spring and summer, making regular mowing essential. If you mow too infrequently, the grass can become tall and spindly, which encourages disease and pests. On the other hand, cutting too often can stress the grass and inhibit healthy development. Striking the right balance by mowing weekly during peak growth and adjusting as needed for the season will keep your lawn looking its best. Proper mowing not only enhances the lawn’s appearance but also supports its overall health, ensuring you’ll enjoy a lush, vibrant yard all season long.
How Often Should You Mow St Augustine Grass
Knowing how often to mow St Augustine grass helps keep your lawn healthy and looking great. Proper mowing maintains the right height and promotes lush growth. The frequency depends on several factors, such as the season, grass growth rate, and weather conditions.
Understanding the Growth Cycle of St Augustine Grass
St Augustine grass grows actively during warm months and slows down in cooler periods. In spring and summer, it can grow quickly, often needing more frequent mowing. During fall and winter, growth slows, reducing the need for regular mowing.
Ideal Mowing Height for St Augustine Grass
Maintaining the correct mowing height is crucial for grass health. The ideal height for St Augustine is between 2.5 and 4 inches. Keeping it within this range helps prevent weeds, retain moisture, and promote dense growth.
How Often to Mow in Peak Growing Season
Spring and Summer Mowing Schedule
During periods of active growth, aim to mow your lawn once every 7 to 10 days. This frequency prevents the grass from getting too tall and reduces stress on the grass plants.
If your lawn is growing rapidly, you might need to mow more frequently. It’s important not to cut more than one-third of the grass height at a time to keep the grass healthy.
Adjusting Mowing Frequency Based on Growth Rate
Monitor your lawn regularly to gauge its growth. If the grass is growing faster, increase the mowing frequency. Conversely, if growth slows, extend the interval between mowings.
Factors Influencing Mowing Frequency
Weather Conditions
Hot, humid weather accelerates growth, requiring more frequent mowing. Conversely, cooler or drought conditions slow growth, reducing mowing needs. Always adjust based on current weather.
Soil Fertility and Nutrients
Healthy, nutrient-rich soil promotes vigorous growth, leading to quicker grass development. Fertilize appropriately to maintain steady growth and mow as needed.
Grass Clippings and Lawn Maintenance
Leaving grass clippings on the lawn can act as natural fertilizer. Mow regularly enough that clippings are small and decomposed quickly, avoiding thatch buildup.
Special Considerations for Different Seasons
Spring
Spring signals the start of active growth. Mow more frequently, about once a week, to keep grass at the ideal height and encourage even growth.
Summer
During hot months, grass grows rapidly. Increase mowing to once every 5 to 7 days if necessary, but always avoid cutting too much at once.
Fall
As temperatures drop, growth slows. Reduce mowing frequency to once every 10 to 14 days, maintaining the proper height to protect roots and prevent weed invasion.
Winter
If your region experiences mild winters, grass growth may continue slowly. Mow infrequently, only when the grass exceeds the upper recommended height.
Tools and Techniques for Proper Mowing
Using the Right Mower
A rotary mower or a reel mower with adjustable blades works well for St Augustine. Ensure blades are sharp to cut cleanly without tearing the grass.
How to Mow Correctly
- Adjust mower height to 3 inches for regular mowing.
- Never remove more than one-third of the grass height in a single mow.
- Vary mowing pattern each time to prevent soil compaction and ruts.
- Clean mower blades regularly for a smooth cut.
Dealing with Thick or Overgrown Grass
If your lawn becomes overgrown, mow in stages. First, cut at a higher setting and then mow again at the desired height once the grass is shorter.
Signs Your Lawn Needs Mowing
- Grass height exceeds 3.5 inches consistently.
- The top of the grass looks uneven or patchy.
- Grass appears dull or has a bluish tint.
- You notice weeds beginning to sprout.
Combining Mowing with Other Lawn Care Practices
Watering and Mowing
Water your lawn deeply before mowing, especially during hot weather. Healthy, moist grass is easier to mow and less prone to stress.
Fertilizing for Healthy Growth
Apply fertilizer in spring and summer to promote steady growth. Healthy grass requires less frequent mowing and recovers quickly from cutting.
Aeration and Dethatching
Periodic lawn aeration and dethatching improve air circulation and nutrient absorption, resulting in a more resilient lawn that responds well to regular mowing.
Summary of Mowing Recommendations for St Augustine Grass
| Season | Growth Rate | Recommended Mowing Frequency | Optimal Grass Height |
|---|---|---|---|
| Spring | High | Once a week | 2.5 to 3.5 inches |
| Summer | Very high | Every 5 to 7 days | 2.5 to 3.5 inches |
| Fall | Moderate to low | Every 10 to 14 days | 2.5 to 4 inches |

Remember, paying attention to your lawn’s appearance and growth rate is key to determining the best mowing schedule. Adjust your routine as needed to keep your St Augustine grass healthy, lush, and beautiful all year round.
The SECRET To Green St. Augustine Grass
Frequently Asked Questions
How does the growth rate of St. Augustine grass influence mowing frequency?
St. Augustine grass tends to grow more quickly during warm months with ample sunlight and sufficient moisture. When growth accelerates, you should mow more frequently to keep the grass healthy and neat. During slower growth periods, such as cooler months, mowing frequency can be reduced. Monitoring the grass’s height and growth patterns helps determine the ideal mowing schedule to avoid cutting too short or stressing the turf.
What signs indicate it’s time to mow your St. Augustine lawn again?
If your grass reaches a height of about 3.5 to 4 inches, it’s typically time to mow. Regularly check the height to prevent it from becoming overgrown, which can lead to thinning and increased vulnerability to pests or disease. Cutting the grass to a height of 2.5 to 3 inches encourages healthy growth and maintains a lush appearance, so keep an eye on the grass’s length to know when your next mow is due.
How can climate affect how often you should mow St. Augustine grass?
Warm and humid climates promote rapid growth of St. Augustine grass, requiring more frequent mowing, often weekly during peak growing seasons. Conversely, cooler or drier conditions slow down growth, allowing for longer intervals between mowings. Adjust your mowing schedule based on local weather patterns and seasonal changes to keep your lawn healthy and well-maintained.
Does mowing frequency change with the season for St. Augustine grass?
Yes, in the active growing season—typically late spring through summer—you should mow more often, possibly once a week. During cooler months or dormancy periods, growth slows, and mowing can be reduced to every two weeks or as needed. Adapting your schedule to seasonal changes helps prevent unnecessary stress on the grass and promotes a healthy turf year-round.
What are the risks of mowing St. Augustine grass too frequently or too infrequently?
Mowing too often can stress the grass, especially if you remove too much at once, leading to weak growth and increased susceptibility to pests and diseases. On the other hand, infrequent mowing allows the grass to become overgrown, which can cause thinning, uneven thickness, and an unattractive appearance. Finding a balanced mowing schedule based on growth rate and season supports a lush, healthy lawn.
