How to Get Rid of Creeping Bentgrass

You pull and pull and those weeds still keep coming back, making you instead want to pull your  hair out. That’s what lawn owners go through especially dealing with a difficult to remove weed like creeping bentgrass. Bent grass is typically found on golf courses and mowed short for the tees, fairways and greens. However, it can creep into a home lawn and give the lawn an inconsistent look. Here we will share with you some expert advice and show you some of the best products that can remove this unsightly weed from your yard.

Creeping Bentgrass Background Information

Creeping bentgrass is a spreading cool-season perennial grass that is commonly used for golf course greens, tees and fairways. Like other grasses, bentgrass can be considered a weed when it is present in another species. The leaves of creeping bentgrass  are typically long and slender. It is bright green in color, so it’s easy to be able to ID it and set it apart from your desired grass.

Creeping bentgrass usually makes its way onto lawns by being blown onto the lawns from the air or perhaps birds are flying by and drop a runner. If you examine patches of creeping bentgrass you’ll notice that it contains lots of stems, or stolons, that extend along the surface of the soil.  These stolons allow bentgrass to spread rapidly among a lawn. Irrigation is almost always required for bentgrass to survive beyond where it is planted.

Bentgrass becomes very 'puffy' when maintained at mowing heights above one inch. It is also susceptible to a lot of different lawn diseases. The invasive weed also doesn’t grow as tall as most turfgrasses and forms mats and patches that are thick and dense all over lawns. This is how creeping bentgrass creeps and if left to it’s own devices without intervention, it will choke out your lawn grass and zap your lawn soil of all it’s nutrition.


Creeping Bentgrass Control Options

Recommended Post-emergent Herbicides:


Complete removal of creeping bentgrass will require a combination of cultural control methods and chemical control applications. Either one of these alone will make management difficult since it is such a pesky persistent weed. Our lawn care experts here at Solutions would recommend first and foremost going with a non-selective approach with Glyphosate or RoundUp. Keep in mind though that since glyphosate is non-selective, you will need to be extra careful not to get the chemical on your desired grasses as it will kill them as well. Tenacity is another good choice because it is a non-selective herbicide and thus will spare your desired vegetation.

Spray about 6 inches beyond the patches to make sure you reach the stolons, or above-ground runners, that may spread out into the lawn, but are often not visible.

This weed will likely require multiple applications.  The most effective time for treatment is when the grass is green and actively growing in spring or fall, not when it’s brown and dormant in mid-summer.

Once the grass in the treated area is dead, rake it out and reseed the spot. However, since the seeds can survive a year, you will need to also treat your lawn with a pre-emergent product in the fall and the following year.


Creeping Bentgrass Tips and Recommendations

  • Make sure to use a surfactant when treating creeping bentgrass to combat surface tension and help make the herbicide stick to the leaves. Mix the surfactant with your selected herbicide and water. Add the ingredients to a tank sprayer and spray directly onto the patches of creeping bentgrass.

  • To use herbicides safely and successfully, follow the manufacturer's label carefully. Application rates can vary based on the selected herbicide you are using.
