Article in English: The best way to deal with groundhogs is to be proactive, and keep them from making their home in your garden to begin with. If you already have a groundhog problem, come back to this section when you have gotten rid of them to help keep your property groundhog-free.  Harvest vegetables as early as possible.  Remove brush and piles of rock from your yard to help make them feel more exposed, and trim back any overgrown foliage. Because they are prey animals, groundhogs feel most comfortable when they can easily take cover from predators. Remove tree trunks they could use to grind down their teeth.  Fill in abandoned burrows with rocks or gravel.
