I have struggled several years to get my lawn just the way I wanted. But now it's threatened by my neighbors grass which is zoyia. I'm trying to keep it from infiltrating my lawn but it giving me a good fight. I've been using round up at the fence line but I think it's going to breach this year. Does anybody have a way to control the zoyia grass. I like my bluegrass. I have been told to dig a narrow trench at property line so to kill off the roots from zoyia.

I've seen people use the steel Ryerson to stop the Zoysia. That is about all that will stop it, a real barrier.

yep a real barrier that you patrol regularly so it doesn't grow over, under, or around.

Re: Zoyia grass
At the barrier of choice, use a rope wick to apply the herbicide to zoysia plants. Preferably a systemic which will eliminate regrowth of the weed. Prevents overspray on your bluegrass.

Re: Zoyia grass
seems like most either love or hate zoysia grass. my neighbor hates it & has it in his yard. he roundup'd his whole yard a few years back & then planted some nice low maintenance fescue. the the zoysia started sprouting up a few years later. iirc, the zoysia roots are ~3' deep & are pretty hardy.
you could try putting a >3' wide landscaping barrier between your yard & his (another neighbor of mine has done this with success). a trench might work too, but i don't know if zoysia grass clippings could start to take root in your yard?

Re: Zoyia grass
I thought of that myself my neighbor just cuts his grass along with his weeds and really doesn't care. So as he's cutting the cuttings blow out from under his lawn mower as he cuts with I assume a mulching blade setup.

Re: Zoyia grass
Don't know how long of a property line you have or what is in between. If possible I would have a line of shrubs with mulch or at least a mulched area that would naturally separate the two kinds of grasses. Zoysia is by far the slowest spreading warm season grass and you don't have to worry about seed spreading.
I admit I am a huge Zoysia fan and wouldn't have anything else but it is so slow to spread that if I have a one foot diameter bare spot it can take over two years to fill in. So if there was a mulched strip or bare ground so you weren't treating both kinds of grasses, a little Roundup every couple years should keep the zoysia at bay.

Re: Zoyia grass
Whatever I have to do before it breaches my property I will do. I have a friend who has the same problem and now his neighbors zoyia moved right on in and took over 1/3 of his back lawn. He is p$&@ off. I told him several years ago to use round up commercial strength but he did not. I also was told the zoyia roots move ahead underground like crabgrass before emerging above ground.

Re: Zoyia grass
Now that Monsanto's patent is up on roundup I am expecting someone to release a Roundup Ready Bluegrass. I live way out of Zoysia territory, but I never got why people hate it so much. It is very durable and has great herbicide options such as Atrazine. Anyway sorry for getting off topic. I would plant a barrier, and fill it with a broadleaf hedge. Then spray it with grass killer a couple times a year

Re: Zoyia grass
We had the same problem with it growing into our yard from the neighbors when I was cutting yards, and some of our rental properties (which I mowed) were overrun with it.
Yes, the roots run deep and can go great distances horizontally before reappearing again.
Now I live in a much wetter place where my biggest "problem" is moss, which I have made peace with, and we both coexist happily (it's green and beats walking on mud).

Not only should you build a barrier to keep the Zoysia out, you should make the Zoysia pay for it.

Re: Zoyia grass
I've got two areas where it's been creeping in. I don't really mind it, but it takes FOREVER to green up in the spring. What I REALLY want to get rid of is the darn Bermuda that's been creeping in. It isn't even supposed to be hardy this far north (NJ)...

I have a patch of zoysia in my front yard and love it. Out grows slow and requires much less maintenance than the **** Bermuda that's common here. Plus, it's great at keeping weeds out! Too bad it costs so much money to start, and in not sure if the seeds that are now on the market are any good.

3' tall stone wall on 3' deep foundation should do it.
Lawn spray guy here from warm area. Zoysia is nearly impossible to remove. Pull or spray with non selective herbicide (roundup) is your only choice once it has spread.
For Bermuda where you don't want it there is a product called Fusilade II. Not cheap but at .75oz/g it will knock it out.

I was looking at Bayer Advanced Bermuda Grass Control for lawns. It's listed as 0.41% fenoxaprop-p-ethyl. It's not available locally in NJ, but the Bayer Crab Grass Killer is and it's listed as the same ingredient. Is one applied differently than the other? If they're actually different, I can just order it on line.
Tommy
I know absolutely nothing about consumer grade products... But if the ai is the same it should have the same effect.

Fluazifop is the ai in Fusilade II. I know it works and works well as I use it all summer long to remove Bermuda from Liriope and other ornamentals. I would think you would really need a liquid product with a surfactant in order to effect Bermuda.

Nope. I don't know of anything other than roundup that will kill zoysia.

^ ^ ^ ^ Diesel fuel has no problem killing Zoysia !!! 
True Value sells product called TurfLawn that will kill Bermuda/Zoysia that is growing in fescue. It attacks anything with "runners" like Bermuda/Zoysia.
However, it's very difficult to get rid of just Bermuda or Zoysia if they are mixed together. I've got very short Zoysia that is great when it's very thick and healthy. Otherwise, my Zoysia is so slow growing that weeds and Bermuda pops up in any bare spots. I am always digging up Bermuda that is trying to get started in my Zoysia.
OP if you want to prevent Zoysia creep, you need HARD BARRIER buried into the ground at least 6" deep or more. Then spray along there with RoundUp or diesel fuel multiple times a year to kill everything at the barrier.

Re: Zoyia grass
It's being tested already and is near being ready for release, however a lot of states in the cool season grass zone are expected to ban it because of the contamination risk. Scotts initially said it's not a concern because the pollen is "heavier" and won't spread but I'd be wary of any claims made by someone selling something.
I live in Iowa where we have 33,000,000 planted acres of crops, can you imagine the economic impact of hard to kill runaway bluegrass being spread in our ridiculous winds?
