Can Crabgrass Killer Eliminate Bermuda Grass?

Will Crabgrass Killer Kill Bermuda Grass?

When it comes to maintaining a healthy and vibrant lawn, dealing with weeds can be an ongoing battle. Two common types of grasses often found in lawns are crabgrass and Bermuda grass. While both can be unsightly and invasive, they require different approaches for effective control. So, if you’re wondering whether using a crabgrass killer will also kill Bermuda grass, let’s explore the topic in detail.

The Differences between Crabgrass and Bermuda Grass

Before diving into the effectiveness of crabgrass killer on Bermuda grass, it’s crucial to understand the characteristics and growth habits of these grasses.

Crabgrass:
– Annual grass that germinates from seeds every year.
– Thrives in warm-season climates.
– Exhibits a coarse texture and pale green color.
– Spreads through abundant seeds and low-growing stems (stolons).
– Often forms unsightly clumps in lawns.

Bermuda Grass:
– Warm-season grass that is known for its resilience and ability to withstand heavy foot traffic.
– Possesses a fine texture with a vibrant green color.
– Spreads through above-ground stems (stolons) and below-ground stems (rhizomes).
– Thrives in warm, sunny climates.
– Known for its aggressive growth and ability to quickly fill in bare spots.

The Role of Herbicides in Lawn Weed Control

When faced with weeds like crabgrass or Bermuda grass, many homeowners turn to herbicides to combat their relentless growth. Herbicides work by targeting specific plants or plant groups, either by inhibiting their growth or killing them outright.

With that in mind, it’s important to note that there are two main types of herbicides: selective and non-selective.

Selective herbicides:
– Designed to target specific types of plants while leaving others unharmed.
– Often used to control weeds in lawns without damaging desired grass species.
– Examples include herbicides that target broadleaf plants but spare grasses.

Non-selective herbicides:
– Kill a wide range of plants, without discriminating between weeds and desired grass species.
– Typically used to clear areas completely before replanting.

The Impact of Crabgrass Killer on Bermuda Grass

If you’re considering using a crabgrass killer to control both crabgrass and Bermuda grass, it’s essential to understand that most crabgrass killers are non-selective herbicides. These herbicides are designed to eliminate a variety of plants in the treated area, making them effective for clearing large areas or targeting multiple weed species. However, they can also harm desirable grass species like Bermuda grass.

When a non-selective herbicide is applied to Bermuda grass, it will likely cause damage or even kill the grass. While Bermuda grass has some resilience, repeated exposure to a non-selective herbicide will eventually take its toll.

Alternative Strategies for Controlling Bermuda Grass

Given the potential harm non-selective herbicides can cause to Bermuda grass, it’s recommended to explore alternative methods for controlling this grass species. Here are a few strategies you can consider:

1. Hand-pulling:
– Effective for small patches of Bermuda grass.
– Requires patience and effort to ensure complete removal of the grass, including the underground rhizomes.
– Regular monitoring is essential to prevent regrowth.

2. Smothering:
– Involves covering the Bermuda grass with a non-porous material like black plastic or heavy mulch.
– Deprives the grass of sunlight, leading to its demise over time.
– Takes several weeks to effectively kill the Bermuda grass.

3. Solarization:
– A technique that uses the sun’s heat to kill unwanted plants, including Bermuda grass.
– Involves laying transparent plastic sheets over the affected area and allowing the sun’s heat to raise the temperature and kill the grass.
– Requires several weeks of exposure to achieve desired results.

4. Herbicidal spot treatment:
– If the Bermuda grass is present in isolated areas, spot treatment with a selective herbicide can be effective.
– Care must be taken to apply the herbicide only to the targeted grass, ensuring minimal impact on the surrounding desirable lawn.

Preventive Measures for Weed Control

Instead of solely focusing on eliminating established weeds like Bermuda grass, it’s crucial to implement preventive measures to maintain a healthy lawn. By keeping your grass healthy and robust, you can create an environment that is less conducive to weed growth. Here are some preventive measures to consider:

1. Regular mowing:
– Keep your lawn at the appropriate height for your grass type, discouraging weed growth.
– Avoid scalping, as it can weaken the grass and allow weeds to take hold.

2. Proper watering:
– Water deeply and infrequently to promote deep root growth in your grass.
– Avoid overwatering, as it can create favorable conditions for weeds to thrive.

3. Adequate fertilization:
– Feed your lawn with the appropriate nutrients to encourage healthy growth and maintain its vigor.
– A healthy lawn is more resistant to weed invasion.

4. Overseeding:
– Introduce new grass seed to your lawn regularly to fill in bare spots and compete with weeds.
– A denser lawn can crowd out weed growth.

In conclusion, while crabgrass killers can be effective against crabgrass, they are generally non-selective herbicides that can harm or kill Bermuda grass. It’s crucial to consider alternative strategies for controlling Bermuda grass without causing damage to your desirable lawn. Implement preventive measures to promote a healthy lawn and minimize weed growth. Remember, maintaining a beautiful lawn involves a combination of proactive care and targeted weed control strategies.

Can I overseed Bermuda grass after using crabgrass killer?

Yes, you can overseed Bermuda grass after using crabgrass killer. However, it is advisable to wait for the specific period mentioned on the product label before overseeding.
