I live in Zone 5, and Speedwell has taken over about half of my lawn. I would like to eliminate it now, and then plant microclover in the dead spots
SpeedZone Lawn Weed Killer Concentrate 20 oz. is not labeled for slender speedwell so we are uncertain how effective it would be on it. We do carry Drive XLR8 which is labeled for it and should do a good job when applied during the flowering stage of this weed. It should be mixed with a methylated seed soil surfactant such as Duo Stick for best results.
