Wire Grass Killer: What is it?

Wire grass, also known as Bermuda grass or devil's grass, is a common lawn problem that can be difficult to control. It grows rapidly and spreads quickly, taking over your lawn and crowding out other plants. Wire grass has an extensive root system that can make it hard to remove from your yard. Fortunately, there are several effective wire grass killers available on the market.

How to Choose the Right Wire Grass Killer

When choosing a wire grass killer, there are several factors to consider. First, you need to determine whether you want a selective or non-selective herbicide. Selective herbicides are designed to target specific types of weeds, while non-selective herbicides will kill any plant they come into contact with.

You should also consider the type of application method you prefer. There are spray-on products, granular products, and concentrated liquids that you mix with water before applying.

Finally, consider the active ingredient in the wire grass killer. Some common ingredients include glyphosate, 2,4-D, and dicamba. Each of these chemicals works differently and may be more effective on certain types of weeds.

Selective vs Non-Selective Herbicides

Selective herbicides are a better choice if you have other plants in your lawn that you want to protect. These products will only kill the target weed, leaving your other plants unharmed. Non-selective herbicides are more powerful and will kill any plant they come into contact with. Use them carefully to avoid damaging your lawn or garden.

Spray-On Products

Spray-on products are easy to use and can be applied directly to the weed. They are a good choice if you have a small area of wire grass that needs to be treated. However, they may not be effective on larger infestations.

Granular Products

Granular products are applied with a spreader and are ideal for larger areas. They can be more effective than spray-on products because they cover a larger area and distribute the herbicide more evenly.

Concentrated Liquids

Concentrated liquids are mixed with water before application. They are usually the most cost-effective option but require more preparation and care when applying.

How to Apply Wire Grass Killer

Before applying any wire grass killer, make sure to read and follow the instructions carefully. Wear protective clothing and gloves to avoid contact with the herbicide.

When to Apply

The best time to apply wire grass killer is during the growing season when the grass is actively growing. This will ensure that the herbicide is absorbed by the plant and is most effective.

Application Methods

There are several ways to apply wire grass killer. The most common methods include:

  • Spray-on products: Spray the herbicide directly onto the weed.
  • Granular products: Spread the granules over the affected area using a spreader.
  • Concentrated liquids: Mix the herbicide with water according to the instructions and apply with a sprayer or watering can.

Preventing Wire Grass from Returning

Once you've successfully removed wire grass from your lawn, it's important to take steps to prevent it from returning. Here are some tips to keep your lawn wire grass-free:

Maintain a Healthy Lawn

A healthy lawn is less susceptible to weeds and other pests. Make sure to water and fertilize your lawn regularly, and keep it mowed to the appropriate height.

Use Mulch

Mulch can help prevent weeds from growing by blocking sunlight and preventing seeds from germinating. Apply a layer of mulch around your plants and garden beds to keep them weed-free.

Remove Weeds as Soon as You See Them

Don't let weeds go unchecked. As soon as you see them, pull them out by hand or apply a targeted herbicide to prevent them from spreading.


1. Can I use vinegar to kill wire grass?

Yes, vinegar can be an effective natural herbicide for wire grass. Mix equal parts white vinegar and water and add a few drops of dish soap. Spray the mixture directly onto the weed, making sure to avoid any nearby plants.

2. How long does it take for wire grass killer to work?

The amount of time it takes for wire grass killer to work depends on the type of product you're using and the severity of the infestation. Some products may take several days to a week to show results.

3. Can I plant new grass after using wire grass killer?

Yes, you can plant new grass after using wire grass killer. However, you should wait at least two weeks before planting to ensure that the herbicide has had time to dissipate.

4. Will wire grass killer harm my pets?

Most wire grass killers are safe for pets once they have dried. However, it's important to keep pets away from treated areas until the herbicide has completely dried.

5. Can I use wire grass killer on my vegetable garden?

No, wire grass killer should not be used on a vegetable garden. Instead, use targeted herbicides or hand-weed your garden to remove unwanted plants.

Wire grass can be a pesky invader in your lawn, but with the right wire grass killer and prevention strategies, you can keep it under control. Remember to choose the right product for your needs, follow the instructions carefully, and take steps to prevent it from returning. With a little effort, you'll have a beautiful, wire grass-free lawn in no time!
