As winter fades and spring arrives, many homeowners see their lawns turn brown. What's causing this, and how can we fix it? We'll explore the main reasons for brown grass in spring and offer ways to bring your lawn back to life.
Understanding the Causes of Brown Grass in Spring
When winter snow melts, homeowners might see patches of light, yellow, or grayish-brown grass. This discoloration often means the lawn has a common spring disease: snow mold. This fungus grows under heavy snow and makes the grass look matted, brittle, and covered in crust by spring.
By the time snow mold is visible, the damage is usually done. But, there are steps to help the lawn recover. Raking or brushing the affected areas and then watering and fertilizing can help the grass come back strong. If the damage is severe, reseeding might be needed to make the lawn healthy again.
To stop snow mold in the future, experts suggest a few things. Avoid letting your lawn grow too green before winter. Don't fertilize too late in the season. Keep mowing your lawn in the fall. And try to prevent snow from getting too compacted from vehicles, people walking, or animals.
Other reasons for brown grass in spring include:
- Soil that's too acidic or alkaline can be fixed by testing the soil pH and making changes as needed.
- Using herbicides incorrectly can harm the grass.
- Drought or uneven watering can be fixed by adjusting sprinklers and how deep you water.
- Fungal problems like fairy rings or lawn matting might need granular fungicides.
- Insects like grubs or chinch bugs can eat grass roots and make the grass look bad.
- Uneven fertilizer can cause different colors in your lawn.
By finding out what's causing the problem and fixing it, homeowners can help their lawns look green and healthy again.
Salt Damage and Pet Urine
Salt damage is a common reason for brown grass in spring. If you see discolored spots near driveways, sidewalks, or streets, it might be from winter salt. Heavy watering can help by making the soil less toxic for grass. But, if the grass doesn't get better, you might need to reseed it.
Pet urine can also cause lawn discoloration. Homeowners with pets, especially dogs, may see brown or straw-colored spots. These spots often have a ring of green grass around them because the urine hurts the turf. Heavy watering can help, but the problem might come back if your pet keeps using the same spot.
- Female dogs, puppies, elderly dogs, small dogs, and some adult males that squat to urinate can cause more localized damage to lawns.
- Male dogs tend to spread urine over a larger area, resulting in fewer but more dispersed spots.
- Lawn damage from dog urine may resolve on its own as new grass growth emerges.
- Brown spots, the most severe type of dog urine damage, indicate dead and dying grass, particularly in dry or weak lawns.
To fix pet urine damage, you can try flushing the area with water, training your pets, or using pheromone-impregnated posts. Keeping your lawn healthy with proper mowing and fertilizing can also help it recover from salt damage and pet urine spots.
Winter Injury or Winter Kill
Winter injury or winter kill could be why your grass looks brown in the spring. It's important to look at the lawn's history and cultural practices to figure out why. If the lawn came from sod, some areas might not have rooted well, causing winter kill. Also, too much thatch can lead to winter kill, so you need to aerate the lawn to reduce thatch.
Diseases and insects from last year might have weakened the turf, making it more likely to die in the winter. Not hardening off the lawn before cold weather arrived could also cause winter injury.
If watering and fertilizing don't help the brown spots, you might need to reseed them. Watching closely and acting quickly is key to fixing a lawn hurt by winter injury or kill.
In the Dallas/Fort Worth (DFW) area, grasses like Bermuda and St. Augustine turn brown in the cold, but they're just dormant, not dead. The grass type, soil, trees, and concrete nearby affect how the lawn handles the cold in DFW.
Warm-season grasses are tough in heat and drought but sleep through the winter. Adding cool-season grasses like winter ryegrass can keep your lawn green in winter. But, this needs extra care based on your location and soil.
As spring comes, your grass should start to green up again if it was cared for properly during the winter. But if it stays brown, it might have died from winter damage, dehydration, or disease. In this case, you should get advice from a lawn care expert.
Why Is My Grass Turning Brown in the Spring?
Many homeowners see their lawns turn brown in the spring, leaving them puzzled. This change can be frustrating and confusing. Knowing why your grass turns brown is the first step to fixing it.
Drought or lack of water is a big reason for brown grass in spring. During the cold months, grass may seem fine but is actually dormant. When it gets warmer, the grass roots can't get enough moisture from the soil, making it look brown.
- Proper lawn watering, providing an inch to 1.5 inches of water per week, can help prevent grass from turning brown due to thirst.
- Maintaining a mowing height that leaves at least one-third of the grass blade intact can promote deeper root growth and reduce water needs.
Not getting enough nutrients can also make grass turn brown in spring. Just like we need food, grass needs nutrients to stay green. If it doesn't get enough, it will look unhealthy and brown.
- Applying the right type and amount of lawn fertilizer in the spring, summer, and fall can help prevent grass from turning brown due to hunger.
- Professional lawn care services can provide a comprehensive six-step program, including grub control, to ensure your lawn receives the necessary nutrients and treatments to stay lush and green.
Pests, diseases, and other environmental factors can also cause brown grass in spring. For example, grubs can eat grass roots, making it wilt and turn brown. Fungal diseases can spread, leaving behind brown patches.
| Cause | Solution |
|---|---|
| Drought or lack of water | Provide 1-1.5 inches of water per week and maintain proper mowing height |
| Nutrient deficiencies | Apply the right fertilizer in spring, summer, and fall; consider professional lawn care services |
| Pests and diseases | Implement grub control and treat fungal diseases with appropriate products |
Understanding why your grass turns brown in spring and acting on it can help you fix your lawn. With the right lawn care and sometimes professional help, you can make your grass look great again.
Reviving a Brown Lawn
If your lawn has turned brown this spring, don't worry. You can fix it with the right steps. First, find out why it's brown, like from drought, disease, or pests.
Check why your lawn is brown. If it's from drought, watering it more can help. Water it about 1 inch a week, either from rain or sprinklers, until new grass grows and gets to 3-4 inches tall.
- Drought-induced brown grass should turn green on its own with increasing rainfall and cooler weather.
- A weekly inch of water with lawn sprinklers can help revive dormant grass during droughts.
Soil problems like high pH or too much fertilizer can also make grass turn brown. For example, sandy soil might need 10 to 15 pounds of sulfur per 1,000 square feet. Loamy soil might need 20 to 25 pounds.
Weeds and diseases can also make your lawn brown. Weeds take nutrients and water from grass, causing brown spots. Fungal diseases like Brown Patch Disease thrive in hot, humid weather and make grass thin and discolored.
- Too much fertilizer can cause brown spots on grass. Watering well can help wash out excess salts.
- Grubs eating turf roots can make grass decay. More than 10 grubs per square foot means you need to treat the infestation.
- Urine from dogs and cats can kill grass and create brown dead spots. You might need to use ground limestone to fix the soil before replanting.
After fixing the problem, keep your lawn healthy with regular mowing, fertilizing, and watching for new issues. With good lawn care, you can make your brown lawn green and beautiful again.
Conclusion
