Preventing your lawn from turning brown in the winter involves a combination of proper care and strategic planning. By understanding the needs of your grass and taking proactive steps, you can maintain a healthy, green lawn even during the colder months.
Why Does Grass Turn Brown in Winter?
During winter, grass can turn brown due to dormancy, dehydration, or disease. Cool-season grasses may go dormant but typically stay green, while warm-season grasses often brown as they enter dormancy. Cold temperatures, lack of water, and soil compaction can exacerbate browning.
How to Keep Your Lawn Green in Winter
1. Choose the Right Grass Type
Selecting grass suited to your climate is crucial. Cool-season grasses like Kentucky bluegrass and fescues stay green longer in colder climates, while warm-season grasses like Bermudagrass thrive in warmer areas but may brown in winter.
2. Proper Mowing Techniques
- Mow at the Right Height: Keep grass slightly taller in winter (around 2.5 to 3 inches) to protect roots and soil.
- Avoid Scalping: Cutting grass too short can stress it and increase susceptibility to cold damage.
3. Watering Wisely
- Water Before a Freeze: Ensure your lawn is well-hydrated before the ground freezes to prevent dehydration.
- Avoid Overwatering: Too much water can lead to fungal diseases, especially in cool, damp conditions.
4. Fertilize Appropriately
- Use a Winter Fertilizer: Apply a slow-release, high-potassium fertilizer in late fall to strengthen roots.
- Avoid High-Nitrogen Fertilizers: These can encourage growth that is too tender to withstand cold.
5. Aeration and Soil Management
- Aerate in Fall: This reduces soil compaction and improves root access to nutrients and water.
- Mulch Leaves: Instead of raking, mulch fallen leaves to add organic matter to the soil.
6. Protect from Traffic and Damage
- Limit Foot Traffic: Walking on frozen grass can cause damage and compaction.
- Cover Vulnerable Areas: Use burlap or mulch to protect areas prone to wind damage.
Common Winter Lawn Issues and Solutions
Winter Lawn Diseases
- Snow Mold: Prevent by avoiding excessive nitrogen in late fall and ensuring good drainage.
- Brown Patch: More common in warm-season grasses, managed by reducing shade and improving air circulation.
Dealing with Salt Damage
- Use Sand or Kitty Litter: Instead of salt, use these alternatives on icy walkways near your lawn.
- Rinse Salted Areas: In early spring, rinse areas with water to dilute salt buildup.

Yes, but use a winter-specific fertilizer high in potassium. Avoid high-nitrogen fertilizers, which can promote growth susceptible to cold damage.
What Is the Best Time to Aerate My Lawn?
Fall is ideal for aeration, as it helps prepare the lawn for winter by improving root access to nutrients and reducing soil compaction.
How Can I Protect My Lawn from Frost?
Keep grass slightly taller, limit foot traffic, and ensure good hydration before a freeze. Cover vulnerable areas with burlap or mulch for added protection.
Is It Normal for Grass to Brown in Winter?
Yes, especially for warm-season grasses that enter dormancy. However, proper care can minimize browning and maintain a healthier appearance.
Conclusion
Maintaining a lush, green lawn through winter requires understanding your grass type and regional climate. By implementing the strategies above, such as proper mowing, watering, and fertilization, you can significantly reduce the risk of your lawn turning brown.
