Having learned previously what ground hogs like, I planted our greens (collards, kale and some Asian greens) along with parsley, peas and pole beans inside a fenced area. The ground hog was still seen in the yard outside the fence. I believed my greens, etc., were relatively safe although I knew that ground hogs could dig under fences. This fencing only extended a few inches below soil level. The fencing was three foot rabbit fencing.
I haven't studied ground hog psychology but it seems to me that it didn't attack my garden until I ticked it off by adding wire fencing around the bottom of one side of the wooden fencing that runs around our back yard. As soon as I did this the ground hog (or hogs as the case seems to be) went under or over my fence and laid waste to the kale, collards, and parsley and started on the beans and peas. The dinosaur kale, seen here, was wiped out because not only the leaves but the growing centers were eaten. This was not true of the white Russian kale (below) either because they didn't find that so tasty or were interrupted before they could clean that out.

The parsley was also chewed down but looks like it too will grow back.
I had two trellises of pole beans. I put a circle of fencing around one of the trellises. Next morning the beans that were not protected were eaten.
In the fenced area I have a wooden frame with screen covers. The purpose was to grow Asian greens inside protected from flea beetles. One of the two screens had been pushed aside and a few of the greens eaten.
Another loss in the fenced-in garden was some of the soybeans. They had been recently planted and were just emerging and were under the rectangle of hardware cloth that is seen in this photo. The covering was not nailed down and the groundhog just pushed under the edge of it and ate about half of the seedlings.
The groundhog(s) apparently entered the fenced area from the path to the right as there were three or four places where the soil had been moved and there were also bits of fur on the path, perhaps from a hasty retreat when I saw them and came screaming into the back yard. I wanted more than just fur!
