Follow These Easy Tips to Get Rid of Brown Patches on Your Lawn for Good
There's nothing like a lush, green lawn to make your home stand out—but those pesky brown patches can quickly turn your beautiful yard into an eyesore. Not to worry, though, we’ve got you covered with this handy guide on what causes those unsightly spots and how to get rid of them. Ahead, we'll dive into brown patches on the lawn, explore their causes and treatments, and answer some of the most common questions to help keep your lawn looking healthy and green all year round.
What Causes Brown Patches on the Lawn?
Brown patches on the lawn can pop up for a variety of reasons. Here are a few of the main ones:
Fungal Diseases: One of the usual suspects is a brown patch fungus, especially when the weather is warm and humid. This fungus creates irregular, brown, and sometimes sunken patches on your lawn.
Overwatering: It might sound strange, but giving your lawn too much water can actually cause problems. The grass roots can get suffocated, and all that extra moisture invites fungus to move in, which then leads to—you guessed it—brown patches.
Underwatering: On the flip side, if you’re not watering enough, the grass dries out and turns brown and brittle. Lawns need consistent watering to stay healthy.
Poor Soil: If your soil is compacted or doesn’t drain well, it’s bad news for your grass. The roots need air and good drainage to thrive, and if they don’t get it, brown patches can show up.
Pests: Insects like grubs can damage grass roots, leaving behind dead, brown spots.
Chemical Damage: Using too many fertilizers, herbicides, or pesticides can end up harming your lawn and causing brown patches.
How Do I Treat Brown Patches on My Lawn?
The first step to tackling those brown spots is figuring out what’s causing them. Here are some quick tips:
Identify the Cause: First things first, figure out what’s causing the problem. Look for signs like disease, pests, or watering issues.
Adjust Watering: If you’re overwatering your lawn, be sure to cut back and check that it’s draining well. If underwatering is the problem, increase your watering schedule, but be careful not to soak your lawn excessively.
Improve Soil Health: Aerate the soil if it’s compacted, and consider adding some organic matter to make it healthier and drain better.
Address Fungal Diseases: If it’s a fungus issue, use a fungicide as directed (or get a professional’s advice). Also, make sure you’re not overwatering, and keep the grass at a good height when you mow.
Control Pests: If bugs are the issue, you’ll need the right insecticide, or you could talk to a lawn care expert to help get rid of grubs or other pests.
Proper Fertilization: Be careful with fertilizers—follow the instructions and don’t overdo it.
How to Identify Brown Patch Fungus:
Brown patch fungus is characterized by:
Irregular Shapes: The patches are often irregularly shaped, with a tan to brown center and a darker border.
Sunken Appearance: The affected areas may appear sunken or depressed compared to the surrounding grass.
Rapid Spread: This fungus spreads quickly in warm, humid conditions, especially if the lawn remains wet for an extended period of time.
Can Overwatering Your Lawn Cause Brown Spots?
Yes, overwatering can definitely lead to brown spots. When the soil gets waterlogged, the grass roots don’t get enough oxygen, which can allow fungal diseases to take over and cause brown patches. To avoid this, make sure your lawn drains well and don't water it too frequently.
How Long Does It Take for a Brown Patch to Heal on a Lawn?
The healing time for brown patches varies depending on the cause and the treatment. Here's what you need to know:
Fungal Diseases: With proper treatment, brown patches from fungal diseases can start to improve within a few weeks. Depending on the extent of the damage, it might take a little longer for a full recovery.
Watering Issues: If it’s a watering problem, the grass should bounce back pretty quickly once you fix your routine, usually within a couple of weeks.
Soil and Pests: If the issue is with the soil or pests, it might take longer—several weeks to even a few months—for the lawn to fully recover.
Keeping up with regular lawn care can help prevent brown patches and fix them faster when they do show up. And if you’re ever unsure about the cause or treatment, chatting with a lawn care professional can give you some extra tips specific to your lawn’s needs.
