how can i deter squirrals from my pots and planters

Put enough pinecones in the pots that the soil doesn't show. Said to
hurt their paws and noses and they will not try to dig. But if enough
soil shows that they can get their tiny feet into, they will dig up
and throw out the pinecones. Depending on the plants in the pots, the
pine cones might not even be visible.
