Answer: Squirrels can be so destructive sometimes! You might try using one of the spray-on repellents labeled for squirrels, be sure to apply and reapply per the label directions. The squirrels are looking for grubs in the soil so you might consider treating the planting area with a grub control product (be sure to apply according to label directions, making sure the product is safe to use on the particular kind of ground cover you have). Some gardeners also report success with feeding the squirrels as a means of keeping them fed without resorting to eating garden plantings. I hope this gives you some ideas.
