Will it kill grassy weeds withot harming KBG?
Certainty is not labeled for use on Kentucky Bluegrass. We do carry several herbicides such as SpeedZone Lawn Weed Killer Concentrate and Tenacity Herbicide which are labeled for use on Kentucky bluegrass. We strongly recommend that you read over the product label of the product you choose (product label link will be under the picture of the product on each individual product page) to make sure you can use the product on Kentucky Bluegrass and to make sure the weeds you are trying to eliminate are listed. You can search Kentucky Bluegrass on our online store to see other products that may meet your needs.
