Answer: Your best bet (though not an easy effort) would be to trap the groundhogs, release them elsewhere (?), and then construct a wire fence that goes about 1-2 feet below the soil and about 4 feet high. This is just about the only sure way of stopping these varmints from eating your garden. All those sprays and home remedies only work for a while, then the groundhog gets smart (have you seen Caddyshack?) and come back! Have you considered a pet? A good hunting dog patrolling your property would probably also be effective.
