Water your St. Augustine grass about once every 2 to 3 weeks during winter, depending on the climate and soil conditions. Keep an eye on the grass’s appearance and moisture level to prevent overwatering or dehydration. A little attention to watering habits ensures your lawn stays healthy until spring.
In winter, St. Augustine grass requires much less frequent watering than during the warmer months. The key is to strike a balance—watering enough to prevent the grass from drying out but not so much that it becomes waterlogged. Generally, watering every 2 to 3 weeks should suffice, but factors such as rainfall, temperature, and soil type play a role in determining the exact schedule. Monitoring your lawn’s condition is essential. Proper winter watering helps maintain root health and prepares the grass for a vibrant start when the growing season resumes.
How Often Should You Water St Augustine Grass in the Winter
Watering St Augustine grass properly during the winter is essential for maintaining healthy turf, even when growth slows down. Unlike warmer months, you don’t need to water as frequently, but understanding the right schedule helps prevent problems like disease or drought stress. In this section, we will explore the ideal watering practices for St Augustine grass during the colder months.
Understanding the Water Needs of St Augustine Grass in Winter
St Augustine grass is a warm-season grass that grows less actively in the winter. Its water requirements drop significantly during this time because the grass enters dormancy or slows growth. Nonetheless, adequate watering is still necessary to keep roots healthy and prevent grass from drying out.
During winter, your primary goal is to provide enough moisture to the soil without overwatering. Too much water can lead to fungal diseases, while too little can cause the grass to become brittle. Striking the right balance depends on several factors, including climate, soil type, and recent weather conditions.
How Often Should You Water St Augustine Grass in the Winter?
General Recommendations for Winter Watering
In most regions, watering once every two to three weeks is sufficient for St Augustine grass during winter. However, this schedule can vary based on local climate conditions and soil moisture levels.
If your area experiences consistent rainfall, supplemental watering may not be necessary. Conversely, if the weather remains dry and chilly for extended periods, you might need to water a little more often to prevent the grass from drying out.
Adjusting Based on Climate and Temperature
- If temperatures dip below freezing regularly, reduce watering frequency to avoid waterlogging and root rot.
- In milder winter climates with occasional warm days, you may need to water more often, about once every three weeks.
- In areas with dry winters, watering once every ten to fourteen days helps maintain moisture without overdoing it.
Factors Affecting Winter Watering Frequency
Soil Type and Drainage
Clay soils retain moisture longer, so watering intervals should be longer to avoid waterlogging. Sandy soils drain faster, so watering more frequently with smaller amounts might be necessary.
Temperature and Humidity
Colder temperatures slow grass growth, reducing water needs. High humidity levels can also prevent the soil from drying out quickly, meaning you will need to water less often.
Recent Weather Conditions
Check local weather reports for rainfall and temperature trends. During wet weeks, skip watering entirely. During dry spells, increase watering frequency slightly.
How to Water Your St Augustine Grass in Winter Properly
Depth of Watering
Water should penetrate the soil to a depth of at least six inches to encourage strong root growth. Shallow watering encourages shallow roots, making grass more vulnerable to drought.
Timing of Watering
It’s best to water early in the morning. This allows excess moisture to evaporate during the day, preventing fungal issues and disease development.
Method of Watering
Use a sprinkler or hose with a nozzle to distribute water evenly. Avoid overwatering in small areas, which can lead to pooling and increased disease risk.
Signs That Your St Augustine Grass Needs Water
- Gray and dull appearance — indicates the grass is stressed from lack of moisture.
- Slow recovery after foot traffic or shade — may mean the turf is dehydrated.
- Wilting or footprints remaining visible — signs of insufficient water.
- Soil feels dry at a depth of a few inches — check with a soil probe or finger test.
Common Mistakes to Avoid When Watering in Winter
- Overwatering, which can lead to root rot and fungal diseases.
- Underwatering, causing grass to turn brown or become dormant prematurely.
- Watering during the hottest part of the day, increasing evaporation and waste.
- Applying too much water at once, rather than gradual, deep watering sessions.
Additional Tips for Winter Lawn Care
Mulching and Soil Maintenance
Applying a light layer of mulch around the grass can help retain soil moisture and protect roots from extreme cold.
Monitoring Weather and Soil Moisture
Regularly check soil moisture levels with a moisture meter or by feeling the soil. Adjust watering accordingly to avoid both drought stress and oversaturation.
Using Smart Irrigation Systems
If possible, use smart irrigation controllers that adjust watering based on weather forecasts and soil moisture data. This approach saves water and keeps your lawn in top condition.

What To Do With Your Lawn In The Winter!!! (St. Augustine grass)
Frequently Asked Questions
How does winter weather affect the watering needs of St. Augustine grass?
During winter, cooler temperatures reduce the evaporation rate, so St. Augustine grass requires less frequent watering. As the grass enters dormancy, it conserves energy, and overwatering can lead to problems like root rot. Monitor weather conditions and adjust watering schedules accordingly, providing only enough water to keep the soil slightly moist without waterlogging the roots.
What signs indicate that St. Augustine grass needs watering in winter?
In winter, signs of underwatering include grass blades turning brown or dull, and the soil feeling dry beneath the surface. If the grass appears wilted or loses its vibrant green color, it may need a gentle watering. Regularly check soil moisture levels to ensure the grass maintains healthy growth despite the cooler season.
Is it necessary to water St. Augustine grass weekly during winter?
Not necessarily. In colder months, watering frequency depends on rainfall, soil type, and temperature. Typically, once every 2 to 3 weeks suffices if there is no significant rainfall. Avoid watering on cold or frosty days, as excess moisture combined with low temperatures can harm the grass.
Should I adjust my watering schedule if it snows in winter?
Yes, snow provides natural moisture, reducing the need for supplemental watering. Wait until the snow melts before watering again, ensuring the soil is adequately moist. Be cautious of overwatering when snow is present, as excess water can lead to fungal issues or root damage.
How can I prevent overwatering my St. Augustine grass during winter?
To prevent overwatering, always check the soil moisture before watering. Use a soil moisture meter or dig small holes to assess the level of dampness beneath the surface. Adjust your watering schedule based on weather conditions and avoid watering if the soil remains moist from recent precipitation or snowmelt.
Final Thoughts
In winter, watering St Augustine grass depends on your local climate and soil conditions. Generally, you should water less frequently to prevent overwatering and root rot.
How often should you water St Augustine grass in the winter? Aim for once every 2-3 weeks if the weather is dry. Adjust based on rainfall and soil moisture levels.
Consistent but minimal watering helps maintain healthy roots during colder months. Keep an eye on your lawn to ensure it stays healthy without overdoing it.
