Make sure you put up signs all around your plants saying, "NO SKUNKS OR RACCOONS ALLOWED!".
And put the signs down low, about 8 inches off the ground, so they can read them. If you put the signs up too high, the animals won't be able to read them, and it won't work. Lots of people who bury fish with their plants make this basic mistake, and their plants wind up getting dug up by critters.
