i've got zoisa in my front yard (was there when i bought the house) - it's been there long enough that it's through just about all of the lawn. still have some regular grass mixed in, tho.
it's not
growing in the
flower bed. not yet anyway as it's not quite filled in all the way up to the edgers that are around the bed. i'm hoping that the edges are deep enough to keep it out of the bed. if not, i'll just be pulling the stuff up all the time.
yes, it makes for a nice thick lawn.
i don't like it tho as it's rough on bare feet (and i don't wear shoes in the summer unless i have to) and it does take a while to green-up in the
spring. also goes dormant (and turns brown) if there's too much dry weather.
dixie, my dad planted a dozen plugs in the back yard when i was a teenager. in 25 or so years, the whole back yard has turned completely zoisa and it's spread through half of the neighbor on the left's yard.
there are two other yards that butt up to it. i don't know about the yard to the right as there's a fence and i can't see grass. the yard behind doesn't seem to have any zoisa tho, that i can remember. i'll have to take a look the next time i'm over there. at one point, the owners of that property had a
flower bed that extended the full length of the property - right at the borderline, so that may have kept the zoisa from spreading.
not sure, i'll take a look next time i'm there
auntnene, couldn't begin to tell you how to get rid of it. if there's not that much there, you might want to pull up what you can and treat the area with gas. i know! that's really extreme. i don't think any of the regular
weed-killers will get rid of it tho. and i'm not recommending treating large areas with gas, either...i'm talking about small patches a few inches square. if it's further along than that, i doubt you'll be able to do anything about it.
I'm just sick. I called a friend who does chemical treatments on yards and he said nothing will stop it. He said he has completely dug up a yard, taken a layer of soil off, treated it, hauled in top soil and sodded and now, three years later, the guy is getting more patches coming up. I'm just sick. We worked so hard to get a good stand of grass. Is he right? Isn't there something out there that will stop it? 
I didn't know what it was, so I took it to the nursery in town and the man identified it for me, 
When I told him my problem and asked what I should do - he just said, "MOVE"! 
I've been fighting this Bermuda grass battle for about 12 years now, but I think I'm losing the war! 
if that's what you want and many people do! 
I just don't want either of them in my yard because they would take over my landscaped beds and my perennial beds. 
We were looking for anything to cover this mud hole that we moved to and we wanted it to spread as fast as it could...
