I got one round of tenacity on my lawn then i aerated & reseeded 3 weeks ago. I fixed some large bare spots as well. I have new grass growing, but I see more weeds and clover and Crabgrass coming back. Can I now do my second round of Tenacity on this new grass. I'm starting the win the battle looks like, but Crabgrass is still hanging in there on about 30 % of total lawn.
If you have already seeded, then you do not want to apply Tenacity Herbicide to the newly seeded turf until is has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.
