Over-seed TTF with a lot of zoysia present?

I have no idea how this might work.

I'd say the zoysia is 60-70% of the grass that's present.

Advice?

Tenacity as the pre seed and one more after seed comes up.

Zoysia is by far, the hardest grass to deal with. That grass needs to be scalped down to the dirt before anything else is done with it after a kill with RoundUp. Rotary mowers just tangle up when put on zoysia. I have seen that kind of cut done with reel mowers, counter rotating bladed trimmers or else a carbide tipped saw blade on a trimmer.

I did one like this last month. I killed off the zoyzia with round-up then scalped it down as low as i could with a rotary mower before aeration/overseeding of fescue. I had went back 2 weeks later and already had alot of germination, it was getting dark though and i didn't get out to inspect it up close.. I'm curious as to how it will turn out. The customer wanted "all one type of grass" and they wanted it done the cheapest way.

It is possible to substantially suppress zoysia in cool season grasses. Do not for one second think that RoundUp application was the end of the zoysia. Fortunately, zoysia is sensitive to applications of Prograss, Pylex, or Tenacity.

Switched from zoysia to fescue on our personal lawn. Roundup 3x, scalped it and slit seeded the new seed in. turned out fine. Wife wanted a green lawn year round. Fescue is high maintenance though.

I know, just hoping to get the fescue established good and suppress the zoysia as needed when it starts to come back.. They have a good bit of shade, and it was getting pretty thin. They wanted to seed zoysia.. there was just no way it would work with the amount of shade. I was suggesting re-sodding with a zeon zoysia that i thought would be more tolerant to the shade. but they didn't want to spend that much. I'll have to get some before/after pictures, hopefully it works out. I think fescue is a good choice for that property, but the warm season grasses are always gonna be trying to come back. I did the same in my back yard, and I ended up with a great stand of fescue the past year.
