Giving your Collie more activities can help, dogs, especially smart ones like collies, can get bored easily and need something to do such as going on walks or playing or chewing on toys. Kong toys are great for providing a challenge to your dog. If that doesn't help you can also put gravel in the areas where she digs. I've also put a pile of sticks in an area where my own dog used to dig at.
