We take care of our lawn, fertilize, put down the crub stuff 2 x a year. Our neighbor has horrible crubs his yard is just about gone. Is there anything we can do other than what we are doing so that we don't get his crubs? We have spoke to him about treating his lawn but because of his nationality they do not believe in taking care of lawn because it is not edible. We have contacted the city every year but nothing is done about it. Thank you...Diane
