Every year the squirrels and chipmunks have become increasing destructive of my container plants. The squirrels have even pulled out the plants to dig beneath. The chipmunks take dirt baths and trench out the flower roots!! But, finally, I have won the battle with an old fashion toy ....Slinky!! One chipmunk challenged the marigold, entered the rings, laid on it's back and started the daily dirt bath. But, couldn't and immediately left the pot alone.
