I believe it. A variety of grass I’ve always wondered about is zoysia. I’ve seen the ads claiming that it fills in from planted plugs and then is incredibly hardy, and my first thought was that I don’t want anything like that in my yard. Where we used to live, it was tough enough trying to keep the Bermuda grass under control in the garden and flowerbeds. That and morning glories — I curse the idiot who planted morning glories in that yard. Rip the vines up time after time, and they’re back in a few weeks.
Mint is another unkillable plant, but it doesn’t spread too badly.
The neighbor had zoysia sod installed several years ago. It is putting-green beautiful in the summer. But...starts fading out in the Fall...is paper-bag brown by winter....then starts greening up again in Spring. And, incredibly invasive. I built a low landscape block wall to separate our yards...put a planting area with a 2-foot kill zone along the block wall. Anything green in that kill zone is Rounded-up. I should’ve done the same thing on the opposite side. That neighbor has a healthy supply of Bermuda...and it loves MY yard.
One year I bought Zoysia grass plugs from a newspaper ad. They even sent the plugging tool. I planted them according to instructions, and it turned out that I didn’t have enough to cover my whole yard.
I watered and watered and WATERED them, but nothing happened. Oh well, I thought, at least I didn’t spend a lot of money.
After a few years, I started to notice the grass in that area getting thicker. It finally took. Over time, it spread to almost the whole yard and it WAS so thick that dandelions wouldn’t grow in it.
It was tough getting the lawnmower through it, and it was the last grass to turn green in the Spring, and the first to turn brown in the Fall.
Huh, my Mom had mint growing in a narrow strip just outside a 2’(?) high patio wall, and zoysia encroaching on the mixed grasses (not sure what varieties) past the mint. The zoysia eliminated the other grasses and mint easily...
