Our lawn (3 acres) has many patches of bent grass in it. Last year we thought it was snow mold and found out this spring it was bent grass!! There are probably at least 100 patches of it! Best way to kill is round-up? Our lawn company was going to take care of it, but they have not yet shown up to do it and we may need to hire someone else, so looking for some guidance. Thank you!!

Creeping Bentgrass is difficult to control. Pre-emergents do not work to prevent new plants and there are no selective post-emergents that target this grass so you must use a broad spectrum herbicide. Products containing Glyphosphate (such as Roundup) will also kill surrounding grasses and plants if the spray lands on them.

Take care to shield any desirable plants/shrubs before you spray. You may have to do a second spraying in a couple of weeks once you see how much of the bentgrass has died.

Please read the label carefully and follow the directions.

The areas that have been sprayed can be reseeded in 10-14 days.

I hope this is helpful. Please contact AaE again if you have further questions.
