I have Bermuda in places here the geese and chickens like it, there is the nicest lawn of it all around my garden area been like that all winter, I know most folks love the stuff but there isn't a garden barrier that it can't get over, around, or through and once covered in it all non-poly-styrene items will be consumed it's far worse than the Borg resistance is futile the synthetics will survive in some form only it will take a tractor to pull it all up.
I have tried to kill it out and failed I'm thinking a chicken pen on the areas will be the end of it and if that can't kill it I'll call in the other troops, Geese, Goats, and Piggies, I am not a fan of Bermuda grass LOL I also don't like and have none on my place is the stickers goat heads I guess there is another kind that is also called the same, I bought some small bales of Bermuda that was offered as clean and it was full of stickers, I didn't find them at first but I lost a few hens to something that caused them to gasp and not able to breathe well, I thought it was just them getting sick and then learned that they can get the goat heads stuck in their craw or throat and hurt them, I cleaned out all the hay and burned it Started having a lot less problems from hens in that pen and luckily it didn't get started on my place, that stuff is almost as tough as Bermuda to kill out
