How to Get Rid of Bentgrass in Your Lawn

Bentgrass, while aesthetically pleasing in putting greens, can be a nuisance in your home lawn. Its aggressive growth habit can quickly overtake your desired turf, creating an uneven and patchy appearance. Fortunately, there are several effective strategies to combat this tenacious weed and reclaim your beautiful lawn. This guide will walk you through the best methods for removing bentgrass and preventing its return.

Identifying Bentgrass: Knowing Your Enemy

Before you begin your eradication efforts, it's crucial to accurately identify bentgrass. There are several types, including creeping bentgrass and colonial bentgrass, each with slightly different characteristics. However, common traits include:

• Fine Blades: Bentgrass blades are very thin and delicate, significantly finer than many other lawn grasses.
• Low Growth Habit: It typically grows low to the ground, forming a dense mat.
• Intense Green Color: Bentgrass often displays a vibrant, deep green hue.
• Rapid Spreading: Its rhizomes (underground stems) and stolons (above-ground stems) allow it to spread quickly and aggressively.

Confirming your identification is vital before choosing a removal method, as incorrect treatment can harm your desired lawn grasses. If unsure, consult with a local gardening expert or extension service.

Effective Bentgrass Removal Methods

Several methods exist for removing bentgrass, ranging from non-chemical to chemical approaches. The best option depends on the severity of the infestation and your personal preferences.

1. Manual Removal: The Hands-On Approach

For small infestations, manual removal can be effective. This involves:

• Digging: Carefully dig out the bentgrass clumps, ensuring you remove as much of the root system as possible. This is labor-intensive but avoids the use of chemicals.
• Hand Pulling: For smaller patches, gently pull the grass out by hand. Be thorough to prevent regrowth.

Important Note: Manual removal requires patience and persistence. You'll need to meticulously remove all visible parts of the plant and frequently check the affected area for regrowth.

2. Cultural Control: Starving the Weed

Modifying your lawn care practices can create an environment less favorable to bentgrass:

• Proper Mowing Height: Maintaining a higher mowing height can help shade out bentgrass and encourage the growth of your desired lawn grass.
• Soil Aeration: Good soil aeration improves drainage and root penetration, reducing bentgrass's ability to thrive.
• Fertilization: Appropriate fertilization will promote healthy growth in your desired grasses, outcompeting the bentgrass.
• Watering: Deep and infrequent watering will encourage deep root development in desirable grasses, further outcompeting bentgrass.

These methods are eco-friendly and contribute to a healthier lawn overall.

3. Herbicide Application: The Chemical Solution

For larger infestations, selective herbicides can be effective. Always follow the instructions on the product label carefully. The best choice of herbicide depends on the type of grass you want to maintain. Some herbicides target broadleaf weeds, while others are specifically formulated for grasses. Applying herbicides requires careful attention to avoid harming your desirable plants.

Caution: Herbicide use should be a last resort. Always consider the environmental impact and prioritize safety precautions.

Preventing Bentgrass Recurrence

Once you've removed the bentgrass, focus on preventing its return. This involves:

• Regular Inspection: Regularly inspect your lawn for any signs of bentgrass regrowth.
• Proper Maintenance: Consistent mowing, fertilization, and watering will keep your lawn healthy and less susceptible to weed invasion.
• Overseeding: Overseeding with a desirable grass type will help fill in any bare patches and prevent bentgrass from taking root.

By combining effective removal methods with proactive prevention strategies, you can successfully eliminate bentgrass and maintain a beautiful, healthy lawn. Remember to be patient and persistent – results may not be immediate but with consistent effort, you will achieve a lush, weed-free lawn.
