The law probably expects you to do due diligence. In this case it wouldn't be a bad thing to work the neighborhood, going door to door and apologizing for ruining the kid's fun, but making the parents know you don't want to be sued. You are going to want to know these people and you are going to want to be able to associate them with their kids.
You should also let the kids know that you don't want them playing in it anymore.
I hope that is enough. Other possibilities include cutting it down and putting up a kid-proof fence.
