My lawn does not look healthy, so I decided to apply fall feed as it is almost September. It has lot of weeds like crabgrass, clover, etc. So when is the best time to apply Tenacity?
If you are applying Tenacity Herbicide as a post-emergent, then you would apply when the target weeds are actively growing. Keep in mind that Tenacity is most effective in young crabgrass, so it may require more than one application to control mature crabgrass. If applying as a pre-emergent, then you usually apply just before fall overseeding and before soil temperatures drop below 70 degrees.
