How do you keep squirrels from digging in a flower garden?

if you garden is bulbs and perennials you can cover it with chicken wire...the bulbs and plants grow right up through it but the squirrels can't get to your flowers. Place it over your bed when it is dormant then you can add mulch on top of it to hide the wire.
