I'm ready to hit the Broadleafs that are going nutz right now....Turf Type Fescue was seeded almost a month ago and has been mowed twice. Always heard less than full strength 3-way is the thing to do.....but, I want to make fewer trips not more. What's the time range with post-em herbicides and new growth? Does weakened herbicide really have much affect on Broadleafs? (Is it just setting the weeds up for the next app?) Does 3-Way have any affect on seed that has not yet germinated?
