So, Tenacity is more of a specific weed control. what would be a good general purpose weed control?

I am in Ohio and have a few questions regarding Tenacity.
1) Is tenacity used as a all purpose weed herbicide?
2) If i aerorate in the fall, can i apply Tenacity in the spring?
3) How often should tenacity be used for weed control?

Thanks

I live in Cincinnati Ohio. my lawn is in good not grat shape. i would like to start fertilizing my yard this year myself. What are some good pre emergant to use and weed control? and products to use throughout the year, I have some ky bluegrass and tall fescue.

If i hear you correct, if my lawn is established with a few weeds, over seeding isnt necessay? also just use sedge ender in the spring and through out the year to control nuts edge? what would be a good turf builder and weed control to use through the year. and a good kbg seed without a ton of filler

I believe i have a good base to start with. i have some nutsedge, and small amount of crabgrass. my thought was to use sedge ender from now till fall to get rid of nutsedge. then i will aerate the yard and over seed this fall. then iam lost as far as what to do after that and what to use.

I va had the big company doing my yard for a few years now and have a decent base to start with. outside of nutsedge and some crabgrass lawns not bad. I would like to do it myself. i have mostly kbg tall fesscue. i was thinking i would kill off as much of the nutsedge as i can, then aerate this fall...
