If it is happening during the day it may be squirrels; they are naturally curious and love to dig. If it's happening at night it could be skunks. Some of the fertilizer stakes have an ingredient including fish which could be very attractive to a critter. You could try hammering the stakes in farther into the ground and tacking a piece of hardware cloth over the area to prevent digging.
