My MIL has the same problem but her beds aren't raised. I will tell her about the orange and lemon peels. She tried chicken wire but then the weeds grow up and make a mess. She isn't up to removing and replacing and crawling around weeding that patch (83 with both knees replaced). She had a raised bed put in last year after seeing mine and she is thrilled with them. Plus they are on the south side of the house will full sun almost 24/7. She is a happy camper for that bed.
