The previous owner of my house planted a zoysia lawn, which is awful as I live in a cool climate. It's brown for most of the year. After digging up the entire yard for foundation repairs I tried to reseed with bluegrass but the existing zoysia sprouts have grown in and more has invaded from my neighbors yard.
Is there a way to get rid of the zoysia AND prevent it from coming back in from the yard next to mine? I've read about doing a non-selective herbicide spray a few times in August and then seeding with something new but I'm afraid I'll just end up with it creeping back in.
Is there a way to out-compete it with some other cool weather grass specie? Or another way to crowd it out reliably?
