Yes, you should generally avoid cutting St. Augustine grass in the winter. Trimming during colder months can stress the grass and make it more vulnerable to damage. Instead, it’s best to let your lawn go dormant and focus on other maintenance tasks.
If you’re wondering whether to cut St. Augustine grass in the winter, the quick answer is no. During the colder months, the grass goes into dormancy and cutting it can do more harm than good. Winter is not the time for regular mowing; instead, let the grass rest and prepare it for healthier growth in spring. Proper winter care can help ensure your lawn remains lush and healthy when the warmer weather arrives.
Taking care of your St. Augustine grass in winter might seem straightforward, but many homeowners get it wrong by continuing to mow when the lawn needs a break. This warm-season grass thrives in summer and naturally slows down as temperatures drop. Cutting it during winter can damage the crown and roots, leading to weakened growth or even dead patches come spring. It’s a good idea to adjust your lawn care routine and resist the urge to trim during these months. Focusing on other maintenance like aeration, weed control, and proper watering can help your lawn stay healthy until it’s time to mow again.
Should You Cut St Augustine Grass in the Winter?
Understanding the Growth Cycle of St Augustine Grass
St Augustine grass is a warm-season turf known for its lush, dense appearance. During the growing season, it thrives in warm weather and requires regular mowing to stay healthy. As temperatures drop in winter, its growth slows significantly, sometimes coming to a complete stop. Understanding this cycle helps determine whether winter mowing is necessary or beneficial.
Impact of Cold Temperatures on St Augustine Grass
Cold weather causes St Augustine grass to enter a state of dormancy, reducing its need for mowing. When temperatures stay below 50°F for extended periods, the grass conserves energy and minimizes growth. Mowing during this time can stress the grass and potentially damage it. Recognizing these temperature effects is crucial before deciding on winter lawn maintenance.
Should You mow St Augustine Grass in winter?
In most cases, it is advisable to **avoid mowing St Augustine grass in winter**. During dormancy, the grass is less active and doesn’t require regular mowing. Cutting it can remove protective layering and make it vulnerable to cold injuries and pests. However, if the grass is still actively growing during warm winter spells, light mowing might be acceptable.
Reasons to Refrain from Cutting in Winter
- Reduced Growth Rate: The grass grows more slowly, making mowing unnecessary and potentially harmful.
- Protection from Cold Damage: Taller grass provides insulation against cold temperatures, safeguarding the roots.
- Stress Minimization: Mowing can cause stress during a period when the grass is conserving energy and repairing itself.
Exceptions Where Cutting Might Be Needed
While generally discouraged, there are specific situations where minimal mowing may be appropriate during winter:
- Overgrown or Thinned Lawn: If patches are overgrown, light trimming can help promote healthier growth in spring.
- Debris Removal: Removing dead grass blades, leaves, or debris can improve air circulation and prevent disease.
- Safety Concerns: If the lawn has uneven patches or hidden hazards, trimming can improve safety.
Best Practices for Mowing St Augustine in Winter
If you decide that mowing is necessary, follow these guidelines to protect your lawn:
Use Proper Equipment
Ensure your mower blades are sharp to prevent tearing the grass. A dull blade can cause damage and stress the turf.
Adjust Mower Height
Set the mower to a higher setting, around 3 to 4 inches, to avoid cutting too short. Taller grass helps insulate roots from cold.
Limit Mowing Frequency
Mow only when necessary, perhaps once every few weeks, depending on the lawn’s growth. Avoid mowing during frost or cold spells.
Time Your Mows Correctly
Choose warm, sunny days when the grass is dry to mow. Mowing wet grass can lead to uneven cuts and soil compaction.
Consequences of Incorrect Winter Mowing
Mowing at the wrong time or improperly can lead to several issues:
- Damage to Grass: Cutting during dormancy can cause stress or kill parts of the grass.
- Increased Disease Risk: Cutting wet or cold grass can promote fungal infections.
- Weakening of Turf: Repeated unnecessary cutting can weaken the root system.
How to Care for Your St Augustine Lawn During Winter
Even if you do not mow, winter lawn care is essential to keep your yard healthy:
- Aerate the Soil: Loosening compacted soil helps roots breathe and prepares the lawn for spring growth.
- Fertilize Appropriately: Use a winter fertilizer if recommended by your local extension office to supply essential nutrients.
- Control Weeds and Pests: Remove weeds that may compete with grass for nutrients and control pests before they become active.
- Water Wisely: Water sparingly during winter, just enough to prevent dehydration without over-soaking the soil.
Seasonal Tips for Maintaining a Healthy St Augustine Grass Lawn
To keep your lawn healthy year-round, consider these seasonal tips:
- Apply pre-emergent herbicides in early spring to prevent weed growth.
- Gradually lower mowing height as winter approaches in late fall to prepare for dormancy.
- In early spring, gradually increase mowing frequency and height as grass begins to grow actively.
- Monitor for pests and diseases during warmer months and treat promptly.

Choosing the Right Fertilizer for Winter
Opt for a fertilizer high in potassium to strengthen roots during dormancy. Avoid high nitrogen fertilizers in winter, which encourage unnecessary growth.
Dealing with Lawn Pests in Winter
While pests are less active in cold weather, some pests like chinch bugs can still survive. Proper winter lawn care minimizes their impact come spring.
Preparing Your Lawn for Spring Growth
As winter ends, gradually increase mowing height, aerate if necessary, and start fertilizing to promote lush, healthy growth.
Final Advice: To Mow or Not to Mow in Winter?
Overall, **most homeowners should refrain from mowing St Augustine grass during winter**. Protecting the grass from cold-related stress and damage promotes better growth in spring. Light mowing in exceptional cases should be done carefully, following best practices to avoid harming your lawn.
Maintaining your lawn throughout winter involves strategic decisions about mowing, fertilizing, and care. Proper winter management ensures your St Augustine grass remains healthy and vibrant when the warmer months arrive.

How should I prepare my St. Augustine lawn for winter?
Prepare your St. Augustine lawn for winter by reducing mowing frequency, avoiding fertilization late in the season, and removing any debris or fallen leaves. In colder regions, applying a winterizing fertilizer can help the grass retain nutrients and stay healthy until spring recovery.
Can cutting St. Augustine grass too short in winter cause problems?
Yes, cutting the grass too short in winter can weaken the turf and increase the risk of cold damage. It also reduces the grass’s ability to insulate its roots, making it more vulnerable to frost. Maintain a slightly higher cutting height during fall and winter to protect the grass.
When is the best time to resume mowing St. Augustine grass in the spring?
Start mowing again once the grass begins to show signs of active growth, typically when it turns green and grows several inches tall. First mow should be at a higher setting to avoid stressing the grass, then gradually lower the cutting height as the season progresses.
Final Thoughts
It is generally advisable not to cut St. Augustine grass in the winter. The grass enters dormancy during colder months, making it vulnerable to stress if cut. Cutting can weaken the grass and hinder its spring growth.
Therefore, you should avoid mowing during winter unless absolutely necessary. Proper winter care helps ensure healthy, lush grass when the warmer months return. In conclusion, should you cut St. Augustine grass in the winter, it is best to leave it untouched to protect its health and vitality.
